shouldn't be a problem orchidskip: If you need more than a 50 amp breaker then your talking one monster welder. We have a 300 amp out DC stick welder running on a 40 ampbreaker (at this level it runs down to 40% dutycycle) We also have a 210 amp MIG (at 60% duty cycle) and it is not a problem. If you were running them both at the same time and the air compressor kicked on then you'd have a problem. Just need to limit how many things are running at same time.
