Which welder to use
Just sold my Lincoln Tombstone (AC + DC) welder at a real good price using
Craigslist. Seems like every time I wanted to join two pieces of metal, the wire feed welder was handier. Total use of tombstone in 20 years was less than 1/2 hour!! There was one instance when I was trying to braze a broken hunk of cast iron for my portable cement mixer (round indexing thingie that holds the drum in position). My son came by and told me "since it's no an important part why don't I simply just zap it with the stick welder". As stupid as that sounds, it worked and has lasted about 15 years now. Here's what I own: Acetylene Oxygen setup 300 amp wire feed welder Miller 250 TIG welder Lincoln Tombstone welder I'm just a hobbyist and not a good welder. I got the tombstone back in the days when you had to learn how to flip your helmet and do 5 other things at the same time to strike an arc. Naturally (25 years ago) I used the A/O more often. Then (building 300 ft. ± of metal fencing) I got hooked on wire feed and bought a used unit. I bought the TIG so that I could learn and also do aluminum. Question: Everything else being equal (all my welders are on wheels, easy access, they all take the same plug etc.) how and why do you guys decide for which welder to reach? I'm talking, for example, 8-10 inches of non-structural weld on mild steel. Why would you ever reach for the "stick welder" option and start chipping slag? Are there inherent advantages to stick? All replies appreciated, Ivan Vegvary (who still has 15± pounds of old, old electrodes) |

Which welder to use
I am not any sort of expert, but I like stick because I know that if
the joint looks like it spans both sides, there is fusion. i |

All replies appreciated, Ivan Vegvary (who still has 15± pounds of old, old electrodes) As we all know....... Welding is the melting of metal components together. So what technique you use should be dictated by the application of the finished job. So if you cant afford a breakdown of your joint you have to use the safest welding method. Leaving tig aside for the moment, the safest welding is stick. Why? because you can see and control the size of the molten weld pool. All the wire feed welding ive seen doesnt give you this option for the home/hobby/ welder without xray testing etc, To be sure of the strength you want in your joint you have to do a test piece and then test it to destruction Ie bend it through 180 degrees and it should not break the weld.. thats the only safe way for a home hobby welder to get it right. Tig is also the melting of metal but under an inert gassheild. A much neater and accurate weld than stick, as well as being suited for aluminium stainless titanium etc. Hope this helps. |

All the wire feed welding ive seen doesnt give you this option for the home/hobby/ welder without xray testing etc, snip Have you ever used a commercial MIG running say .035 hard wire and CO2-Argon mix? That is my forte and welder of choice for anything in-position and of steel composition. I've never had any problem watching the molten pool and controlling its size (shrug). I can easily weld a 3/8 inch butt joint in a single pass. I would want a backing plate for a single pass though. I can turn the same set-up down and do a decent job welding thin stuff too. If I take the time to change the wire (seldom, too lazy), contact tip and feed rollers, then even thinner stuff is possible. This is the only MIG I have ever used. Never had the chance to play with one of the little ones. Mine is a Millermatic 200 (200 amp @ 60% duty cycle). For most any home shop it can kick some butt . If Ivan really has a 300 amp MIG, that would be my choice for most common steel work. I have stick too, mainly for odd-ball metals that I could buy a few special electrodes for and out of position work. I don't have a TIG -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

You can use one of these for stick, of course, but the smoke keeps you from getting close enough to see what you need to see, and you can't see clearly through it all. Jon |

I have a similar setup but a bit smaller
Miller Sync 200 Lincoln mig pack 15 (175A fcaw and mig) Oxy/Acet (But my O2 tank is a bit small) Is it a bench job, is it something other than steel...... TIG is it outdoors or is the position Wonky FCAW (Portability) Is it cutting then Oxy the only time i might use stick is if i had a very thick weld to do and i would use the synchrowave as the power source. if the job falls theought he cracks in my earlier choices (Outdoor and weird metal for example) then i consider it beyond my ability and tools for now On Nov 14, 1:07 pm, "Ivan Vegvary" wrote: Just sold my Lincoln Tombstone (AC + DC) welder at a real good price using Craigslist.

All replies appreciated, Ivan Vegvary (who still has 15± pounds of old, old electrodes) Penetration. The purpose of welding is to create a molten crucible between (usually) two parent metal pieces and the molten electrode. To raise all three above melting point in a controlled crucible, then moving on. As the molten puddle solidifies, it unites the formerly three into one. That's about as simple as I can put it. With wirefeed, sometimes it doesn't work as well because a lot of the heat is soaked up by the thicker pieces of parent metal, and a weld that looks pretty is actually just laying on top of the parent metal. With flux core wire, the arc is different, and does actually melt the parent metal. This is why you use standard MIG for thin stuff, and FCAW for thick. What you want is for the pieces to stay together. You can "Gorilla Weld" a piece like the mixer you mentioned, and it stays. Is that a good weld? Yes. Is it a technically good weld? No. Weldor skill has something to do with it, too. Stick welding is harder than MIG. Whatever you use, if you end up with a weld that is safe and looks acceptable, that's good. From there, it gets into aesthetics, and from there, it gets into engineering and strength and safety. Steve |

All replies appreciated, Ivan Vegvary (who still has 15± pounds of old, old electrodes) I have not burned one stick since I got a Millermatic 210 MIG. If I had stuff 3/4" or thicker to weld I'd probably go with stick, but that hasn't happened since I got the MIG. As others have noted, it's easy to get "pretty" welds with no strength with MIG, but one who is reasonably proficient with stick should have no trouble making good welds with wirefeed. There's more "art" and control with stick, so one can just start welding and adapt. With MIG, I often do a practice weld on scraps of similar thicknesses to get the machine and my speed set up tits, then have at the job. Total job time is considerably less, with no smoke and no slag. Someone said you can't see the puddle with MIG. You certainly can if it's running right. You can't make a good weld with any machine if you can't manage the puddle. For very precise work, particularly small stuff, the TIG is my first choice. Slow, but very controllable and very versatile. As one wag put it, you can about weld dog**** to windowglass with TIG. Autogenous welds (no filler) are easy to do with TIG, and sometimes they look really nice with ample strength for the application. I use O/A only for brazing, silverbrazing, and welding of thin aluminum sheetmetal. |

I have a smallish Miller Thunderbolt stick welder and a Millermatic 250 MIG welder, plus others. I am building a steel beam stairway right now, and on the upper floors of the structure it would be nearly impossible to get the large MIG welder up there, so I carried up my little stick welder. Lots of wind up there, no problem with stick. Also recently we were erecting some steel I-beams on site. We had to weld 20 feet in the air on 12" I-beams. Easy to just add a length of welding lead to the stick welder and pull the leads up there - very difficult to extend the MIG gun. I almost always use the MIG welder, though. GWE |

I suppose it's a matter just like so many others in the welding trade:
what fits your hand best is the process to use. To me, stick welding is the basic process, it's what I consider first. I'm comfortable with it, I like the way things happen and I find it's the process that offers the most freedom to approach the job as I wish. John |

Used to have a big AC Only "buzz box" but I sold it, Didn't use it a lot and it took up a lot of space. I got the wire-feed in exchange for some work on a neighbour's Honda GL - have not used it much - much more comfortable with the old stick welder. Or the O/A for light stuff and brazing. -- Posted via a free Usenet account from http://www.teranews.com |

I've found that even black millscale on new HRS can significantly affect the quality of wire welds, GMAW or FCAW. With stick you only need strike an arc once per stick, while wire (at least until entering spray-transfer regime, which smaller machines never do) must strike repeatedly and often though the user may not be aware of it. That nice "bacon frying" sound when a wire welder is set right and running well is the arc repeatedly striking at a consistent rate. Wire works best with clean metal. |

They might go out and weld on a trailer, or something that is critical. An experienced welder would know, as you and I do that watching the puddle to make sure the parent metals are melted is the thing to do. And how to position the metal so that a big crucible of molten metal can be created easily and effectively. But a newbie might not. So, rather than have something like that on my mind when I read about a trailer taking out the minivan and the three kids in Sheboygan, I am reluctant to give hard and fast recommendations. That's why I said that each job requires the weldor to choose the proper welder. For me, when I want to weld something and KNOW it's three times stronger than it needs to be, I use 7018. But most people can't run a stick of it with two weeks practice. I have four x ray certs with it. So, I don't tell them they need to use 7018 even though it's probably the thing to use on some heavier applications. Welding is fun. From there, if you are welding anything structural, roadworthy, or just plain has to stay together under hard use, you enter another dimension. These MIGs today are a heck of a thing for the average hobbyist. Anyone considering getting one, please do yourself a favor and buy only Blue or Red. Steve |

I really regard it as a 3000 GVW trailer because that's what the tires are good for and I put a 3000-lb springset on it, (40 bux at Northern) but I know my neighbor has loaded it considerably heavier than that with no problems.

wrote: snip I agree, Leon. It's just that it's not a good idea to tell newbies that it's totally okay. They might go out and weld on a trailer, or something that is critical. An experienced welder would know, as you and I do that watching the puddle to make sure the parent metals are melted is the thing to do. And how to position the metal so that a big crucible of molten metal can be created easily and effectively. But a newbie might not. So, rather than have something like that on my mind when I read about a trailer taking out the minivan and the three kids in Sheboygan, I am reluctant to give hard and fast recommendations. That's why I said that each job requires the weldor to choose the proper welder. For me, when I want to weld something and KNOW it's three times stronger than it needs to be, I use 7018. But most people can't run a stick of it with two weeks practice. I have four x ray certs with it. So, I don't tell them they need to use 7018 even though it's probably the thing to use on some heavier applications. Welding is fun. From there, if you are welding anything structural, roadworthy, or just plain has to stay together under hard use, you enter another dimension. These MIGs today are a heck of a thing for the average hobbyist. Anyone considering getting one, please do yourself a favor and buy only Blue or Red. Thanks for the good follow-up Steve. I knew you were a welder, now I know you were just being cautious. Welding items/stuff that can cause serious injury when it discombobulates shouldn't be take lightly. I tell you what though, if I crank up my machine high enough to weld 3/8 inch in single pass you end up with one hell of a puddle. I would guess that the metal is solidifying anywhere from 1 to 2 inches behind where you are currently welding too. You need some pretty good positioning and thought given to what you are doing or you'll get a bum weld. Several passes at lower settings is a whole lot more controllable. -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

It is a nice feeling to be welding hard for ~20 minutes or so before the cooling fan kicks on and then only runs for a bit. Sometimes I get the whole job done and the fan never comes on I had it fired up a few weeks ago after several years of rest to fix a neighbors mower deck. No different than the last time I used it. Need to push myself away from the computer more often I guess... -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

Question: Everything else being equal (all my welders are on wheels, easy access, they all take the same plug etc.) how and why do you guys decide for which welder to reach? I'm talking, for example, 8-10 inches of non-structural weld on mild steel. Why would you ever reach for the "stick welder" option and start chipping slag? Are there inherent advantages to stick? All replies appreciated, Ivan Vegvary (who still has 15± pounds of old, old electrodes) Tomorrow I will be welding some pipe to make something like a swing set that I can use with a come-a-long to lift stuff. I have a wire feed welder and a TIG welder, but expect I will be using an AC stick buzz box. Why? Why not. I would have to change the wire to use the MIG, and the stick welding is slightly faster ( IMO ) than TIG. Also don't have to turn on and off the gas and water. Dan |

Well, obviously, the bolts you had in it were too big. I mean, if it will hold with half of a 3/4 bolt gone, that's to much bolt in the first place. pyotr p.s. "Try wait" - it just occurred to me, though, that if the bolts had been 3/8, they would have worn through before you checked them. You'll need to run the Preferred Maintenance according to the schedule, in that case. Or just go back to using the 3/4 bolts, and over engineer things. :-) -- pyotr filipivich "Quemadmoeum gladuis neminem occidit, occidentis telum est.

Right now the bed is attached to frame in, maybe, 15 points or so, but with tilt there would be only two points. IMHO to do a tongue-pivot tilt you really need an A-Frame style tongue, and depending on how you do it that would leave three or four attachment points - the two pivot points at the framerails, and the two saddle points where the tongue A meets the body front apron or the frame front crossmember. You could leave the straight tongue you welded into the chassis structure as a stub for the tilt cylinder to attach to. My 5x10 utility trailer was a tilt. Those two 3/4" bolts holding the frame to the tounge started bothering me, so I pulled em to check em. Found both of them nearly worn half way through. No bushings or bearings....just steel to steel.

I was thinking about welding them together..but...someday I may want to tilt. Scary **** when you pull those bolts and find only 3/8 of material left, considering the loads Ive had on it. Gunner: But someday you may *need* to tilt, there's a huge difference. You get a load on there that for some reason has no other way to be safely unloaded than to be tilted and slid off. Next time you are messing with it, take out the bolts and tip it a bit, then hog out the holes and weld in bushings. Then you can apply some serious clamping force with those bolts, and the friction of the frame arms against the tongue will keep the whole thing from moving. If you try clamping down hard as it is (with the holes unbushed) you can distort the tongue - and that crease in the normally nice straight load-bearing sidewall of the tongue tubing will create a starting point for a bending failure of the tongue. Hitting a sharp bump and having the tongue fold under is not a good thing. The axle has drum brakes but we never got around to hooking them up to anything. Tongue is 4" x 4" square tube, I think the frame and bed cross supports (2) are 2" x 4" rect tube. I once saw another remarkably similar to it at the steel yard, and the owner said he routinely loaded his to 4000 lb. Don: While you aren't in a "Gotta do it right now, pay any price" rush, I would go look for a surge control tongue or an Electric-Hydraulic brake controller for your trailer. It's not the dead-weight load the trailer can handle, it's the GCWR of dynamic mass that your tow vehicle can get stopped quickly and safely. And with smaller cars and SUVs comes smaller brakes. It's no fun to need to panic stop and feel the trailer start dancing the watusi behind you. BT, DT. If you ever have to do it while going around a corner, you are seriously screwed - it'll jackknife you and if you're very lucky you'll end up out in the cornfield, if not you'll be in oncoming traffic, picking ARMCO or K-Rail out of your teeth, or following Wile E. Coyote off that conveniently placed cliff... The Electric-Hydraulic ones are nifty - it's a little pump that applies the hydraulic trailer brakes with standard electric brake controller signals (*but the controller has to be rated to drive them, the old ones aren't) and a breakaway system with backup battery that clamps them down hard just in case. Note that there are separate designs for drum or disc trailer brakes - residual pressure valves for drum. -- Bruce -- |
