I came upon another Apex welder in better nick (appearance) than the previous unit. It came with a new BOC welding hood, 15 metre HD leads and a pack of rods.
It works real smooth; the drawer back was, it had a breakaway of the dielectric(?) material above the slide choke.
Maybe caused by abuse from being dropped, being hauled by the choke or overtightening. Any way I have seen similar damage on these before but never a complete breakaway.
This is what I did for a repair using Formica electrical board and West System epoxy; all that remains to be done is drill through and attach a 40 x 20 ali angle support plate for added peace of mind and in case I ever lend it to a 'carefull' friend:) .

Slick repair speedy but have you tested its operation?

Thanks Steve. I am happy with the look of the repair.
You mean, it was working well before but will it functuion the same after the repair?
I am hoping so:)
Before commencing the repair I spoke with Jim, my electrical engineer mate. He tells me that the material will have no effect on the function.
Should I trust him?:D

As long as the material is non-metallic it will be fine. You could of even used wood.

Thats the first time I have ever seen a welder with a manual shunt like that.

It's a saturable reactor, lets you change current without switches or jumpers. Moving the metal block in or out changes the saturation current.

Saw wooden staves in a power plant generator..
They were wedges put in the coils.

OK..

I have saw them rascals adjust themselves as you are welding.. the ones I have had open had screws and threaded rods to adjust them..

Sticking a metal object in between two coils? well ever stick a fork into a toaster oven to get a burning piece of toast out. It imparts quite a charge to the fork.. and you..

This isn't mine but is identical. Shows the choke and locking set up.
The sliding choke is a lump of aluminium with laminations contained within phenolic insulator bolted to the end. I will post an image later when I have finished.
They are a nice welder with the low amp range 30-55 and the high amp range 55-150 over the same distance on the choke slide.

Well, I finally got round to finishing the welder.:eek:
I fabricated a 'front bumper iron/ lifting point' (courtesy of a supermarket shopping trolley and an exercyle) to protect the choke and the cable connectors, fitted a heavy duty handle ( galv water pipe). I also reversed the axle to bring the fulcrum forward a notch as it was a b*tch to tilt back - the point of balance was rubbish. All electrical connections were resoldered, cleaned or replaced .
She is all good.

This is my refurbished 4 wheel steer 180SC. A solid unit as well.

Speedy...Fix looks real good! I agree about the handle. I had a "C" clamp on the back side of my Lincoln buzz box for that same reason. Some mornings I didn't have enough ballast to tip it back. ;)
