Ive always thought stick welding was a black art.

Not black art but one of those things where 1) it's much easier using
the right gear 2) in the right position 3) on the right job (to start
with especially) and 4) ideally with a mentor to give you tips re the
approach and what is right (setup wise, rather than what should right.
The books / chart says 60A but in fact on that particular setup you
actually *need* 75A etc).

I have found being able to get into a comfortable position helps greatly
- even simple things like when using a new (i.e. long) rod,

Oh, absolutely, irrespective of the log rod etc. But then I guess that
applies to most things? weg

using my
free hand to prop the electrode somewhere nearer the business end, makes
for a much easier job of keeping it where you want and not waggling all
over the place!

Yup, (although you need decent hand protection for that) and again,
yer overall position (you and the job) can determine how easy things
can be.

p.s. Whilst I could weld (stick / gas) and had my own gear from an
early age, I got loads of good mentoring from a coded welder who
really did make it look so easy. Even welding a h/d pipe overhead in
cramped conditions. ;-)

I count anything under 2' from the ground as cramped conditions these days!

I'm still ok on my haunches (for a short time) but cant just spring up
from that position like I used to. So, on the floor is ok, or sitting
an a low to high stool or standing is ok. Welding overhead can be
'fun' for other reasons than lack of comfort.

When I replaced the 8' square up-and-over garage door that came with
my (what was to be) workshop, I replaced it with a square arch
'subframe' (100x100x12mm" angle) and 3 fanlites at the top and a
bi-fold door and personal door at the bottom (doors 6'6" high).

I dragged out the stick welder to weld the top fillets as I needed
something a bit 'punchy'. I was ok, up on the platform, my mate below,
steadying it whist I got the tacks in, not so. I think I had to treat
him to a new jumper. ;-)

The top frame / opening windows were all in lighter angle (wired
glass) and the doors were 50x25x1.5mm steel box, clad on the inside
with steel sheet (so that could be skinned with something more
decorative on the outside within the frames).

I put the horizontal steel cutting bandsaw, MIG welder and (very old,
bought with the SIP 150) B&D 'Pro' angle grinder to good use on that
project. ;-)

Start with thinner sticks! They are less sticky.

If the rod sticks, wind up the current setting.

Right rod for the job. Thicker steel=thicker rods.

Rule 2, bend the rod. This allows you to watch the weld progressing
without the stick holder getting in the way.

No, not on mine John but I did replace the std mains lead for a much
longer (orange) one as you *typically* have to plug them into an
extension lead to be able to do anything other than just stuff on the
bench.

(I still have one going strong that I got in the late 80's)

Mine is black, if that helps (I'll see if the info plate is still on

But that's got me thinking ... could it be a Bosch pro ... black
rather than green?

It would be interesting to know how many amps it really delivers. There
are youtube videos showing that some of the Chinese stuff doesn't meet
the claims.

But welding 3.2 is impressive. My Lidl cheapy (£75 or so) won't go
beyond 2. Or at least, not for me :-).

I agree that they are amazing, though.

60% according to the page... and less than £40 from China (+

Yeah, I saw that ... and where it was from so I was interested in the
real world value. ;-)

Also, does '60%', even if valid, give you any idea of how long you can
weld for before it might thermally trip? 6 minutes on, 4 minutes off
.... 60 seconds on, 40 seconds off?

And if it's 60 seconds at 20A ... ? ;-)

I use 2.4 rods and it seems to go forever,I don't build ships with
continuous long welds and I do not suppose it would be suitable,but
workshop or field work of weld a bit get another bit of metal and weld a
bit more it works easily.

I used the stick lead from my bigger MIG And made an earth from an old

bangood fairly cheap.

For years I have used a very basic SIP Merlin AC Arc welder (mostly
repair work, sticking the mower deck back together, and the occasional
bit of crude fabrication). Its a transformer based lump, pretty crude
with a ridiculously poor duty cycle (weld for 7 mins, let it cool down
for half an hour - improved to weld[2] for 7 mins let it cool for 15
with the addition of a couple of large fans internally). However I put
up with it on the grounds that I don't need to weld things that often.

[2] In fact never mind welding, just turn it on a wait for ten mins
and it will overheat and cut out all by itself.

However the thought also occurred to me that one of the reasons I
don't need to weld that often is because its such a PITA to use, one
tends to find alternative ways of doing it! That and it might be quite
nice to be able to do some proper fabrication work from time to time.

So earlier in the year when an excuse was presented[1] and I finally
got round to upgrading to a decent inverter based MIG setup, which has
been really nice. At the time I bought it I also got an electrode
holder so that I could also stick weld with it if I wanted - but had
never got around to trying it out until today.

[1] Daughter needed to do some welding for a college project, but
could not go in due to lockdown.

I wanted to weld up some bits of rebar outside, and the wind was quite
strong. So, ideal time to try it in MMA mode...Â* and wow what a
difference! You can strike an arc with ease, it runs quiet and smooth
with a really nice stable DC arc, and makes it almost easy to get
pretty decent results with relatively little skill or practice. No
buzzing, spluttering, or sticking either.

So moral of the story, I wish I had gone for something like it years
ago, and I now have a new found respect for IGBT inverter arc welders
- they make the whole process quite civilised!

(anyone got a use for a 150A Merlin?)



I did something similar a few months ago and wish I'd done it much
earlier. I'd had a large'ish transformer-based MIG welder for a looong
time, it worked well-enough but I used it so rarely that my welds were
always a bit embarrassing, which meant I used it less. I took the plunge
and bought a 180 inverter MIG/MMA from R-Tech and using it is a totally
different experience to using the old welder, I also switched from using
CO2 pub gas to an Argon mix. Welding is so much easier and gives
excellent quality, plus the box is much smaller and lighter. There are
cheaper units out there but R-Tech were helpful on the phone and have a
long'ish warranty. They aren't cheap, but I sold the old welder so the
upgrade cost was affordable and well worthwhile. I thoroughly recommend
R-Tech and the 180 MIG welder.
I still use CO2 as I can fill cylinder with dry ice pellets for AU$5.00
per kilo

Start with thinner sticks! They are less sticky.
You can get rods here called satincraft which are easy for beginners
