picked up a hobart ac/dc tig the other day for $200. Also come with a plasma cutter. The name on it is Power Mate. Model is 118-004. I can not find any info on the internet about it. Called the local praxair store and thay don't have any info on it. The name plate says secondary is 40 amps, duty cycle is 40%. Has any one herd of this brand? Im looking for parts.
