TIG with Pulse feature
I am planning to build a tube chassis vehicle and I want to invest in
an AC/DC TIG welding machine. The thing is, there also is a similar TIG welding machine with a Pulse feature. Is this feature necessary? or do I just buy the AC/DC TIG without the pulse feature? |

Some people take to the pulser like a fish to water, others find it
frustrating and hard to adjust. I would try it first before purchasing. I don't see much use for it in your stated application. The pulser is used to control heat input on thin sections or in high amperage applications. Neither which applies to tubular frame construction. If given the choice I would spend the money on a water cooler. Not a necessity but much more useful. starbolin |

TIG with Pulse feature
I have the Squarewave Tig 175 also. Snagged the Lincoln 175 Pulser on
Ebay a while back. Vastly expanded the quality and range of the welds. You can literally weld pop cans with it. Best upgrade I ever got.

TIG with Pulse feature
the TIG welding machine I'm planning to buy can be switched between AC
and DC, which gives it more flexibility in the metals it can weld. Some welders told me that many people have problems with achieving sufficient weld penetration with a MIG. Most expert recommend TIG so I'm just following their advice.

TIG isn't necessary (or it could be argued, appropriate) for what you want to do. Nice welds, if you have the skill, but overkill for doing a nice job on fairly heavy tubing. MIG for speed. Stick for cheap. TIG for neither of those. :-) If you don't know whether the pulse is a requirement, you probably don't need or want it. Now, if you wanted to get into welding your own aluminum tube frame bicycles together, pulse would be quite a handy thing to have, I think. Cheers Trevor Jones (Who also want a TIG machine in his shop!) |
