Inverter, super-light weight, do low penetration welds wherever you like....

I have an old Airco transformer TIG machine that I will give to you, works great! of course it weights about 1500 lbs
(680 Kilos) so the shipping may be a bit!

It's a new day, I'm not a quitter...( I have to be honest it was at the top of the list of practical solutions).

I rang the service guy. He hasn't called me back since our conversation which is a definite positive as he said he would look at my old machine immediately and if it was a simple issue he'd do it without further discussion.

Sometimes explaining a problem, or indeed a whole seemingly interlinked clusterfinkelstein of them can help beyond sitting there trying to nut them out with a busy conversation in your head.

"The wire is wandering, it's impossible to lay a straight bead, like the wire is being distorted"

I went back to the shed. I reduced the roller pressure til it wouldn't drive and then inched it back up till it did...I looked at some of the pieces of wire that I'd pulled out of the wire guide after the roller had bunched it up, sure enough they were flat on one side...idiot...that solved the wandering wire issue.

 Then I had a bout of lateral thinking. I reversed the torch angle. For me "hot spotting" has always worked best on light Al sheet. So I started with a "pull angle" and about 3/4 inch stick out so it's into spray transfer. I'd start each "dot" by aiming at the bottom edge of the previous one, this way the strike is better, it is right in the root of the weld and has the thicker area of the previous spot to dissipate some heat.....

I've got some off cuts from the original build of the car, I put .040 cuts in them and the welds are starting to look OK, not like I'd brag about them, and if you need your Coke can repaired go elsewhere but I'm no longer as Nick Cave would moan, deep in the woods.

Thanks for the offer Rex but I try to use welder I can take to the job rolleyes rolleyes rolleyes

Doc,

we used to sand blast every surface before welding aluminium to clean the joint of oxide/dirt/etc. Are you still doing that?

This reads like it is MIG welding.  A spool gun gives controllable and consistent feed with aluminum wire.

Using a stainless brush and acetone, by next week they will be chasing me to make the Space Shuttle, is that still a thing?

Just like the plane that fired a few shots at WH700 the Canberra that our tank came from....
spoolies aren't that common here.

I had somethiing similar. Got rid of it when I moved from the shop. We used to call them a Pie Warmer
They had a set of points for the AC. Apart from it being really big, it was also three phase (480 volts)
Like most of Australia, I only have 240 at home

My old ARCO (Which turned into Miller Welding) has a number of input power taps from 220 single phase to 480 three phase and if you put the power control in "kill" the max output is 460 amps! now that will melt your torch hoses fast!

I did build a pretty nice trailer with it and if you use 3/32 rod it will lay out a pretty nice fillet at around 200 amps.

One of my short careers was working as a service guy in earthmoving
I've broken a lot of 13/16 sockets tighening up track plates
and laid a lot of stallite on buckets and blades with a big DC welder

Same here but with grader blades.  Welding hard face on blades is an essential but extremely boring task.
