Oxford 200-1

[Olderisbetter]

We moved my Oxford 200-1 today to the unit to weld some beams, it was used on full.power for about 30 minutes the just stopped working, all the lights are on and fan but when you pull the trigger nothing happens , we were doing well till then

Unfortunately, I don't think a 200 amp Oxford mig is up to that type of structural welding, personally.

An Oxford 180 stick welding unit would have been my minimum weapon choice...imho

oops, I always used stick on heavy steel....

Yes it's gone back to normal, it was hot hear yesterday so maybe a combomof that and pushing it too much

just gone into thermal protect ,,, nice when protection works the way it should .

Probably hit the duty cycle - e.g. if it says duty cycle @ 200 amps is 30% then that means in 10 minutes you can weld for 3 minutes before it would hit the limit

On the production welders (Norman Butters sets) we would bypass the thermal protection and put a big fan behind the sets when the weather got too warm in the 80's.

Ill not tell you about some of the '' protection '' Ive scrimped on in the past ,,,,, or some of the outcomes either .

Maybe stuff a firecracker in the main windings ?
Along with the sound, the smoke should do the trick.
