I looked at the welder again today. I was wrong. Its 40 amps on the settings not 40 amps draw.

It's a 50 amp cord with a 20 amp pigtail.

We tested it again with the 220 cord off his MIG. about 2 min and that cord was melting. To rule out his 50 amp circuit we switched the machine over to 110 and put the 110 cord on and it instantly melted that one also so we took the machine in and dropped it off. Lincoln. Is gonna warranty it. We also gave them the 3 burned cords.

They wont pick it up till next Thursday so it will be a while before we hear what the problem is.

I'll say it once more..... this machine really should not be on a 50A breaker; it does not pull nearly that level of current. The fact that it is pulling enough current to melt the cord but to NOT trip the breaker is proof. Look up the current level versus time-to-trip on ANY breaker; 55 amps on a 50A breaker will take many MINUTES to trip the thermal section. You don't have adequate overcurrent protection for this machine's cordage with that 50A breaker.
