I have the PP256.

This Winter my project was to weld a dozen Aluminum Fireworks Finale pods out of 2" angle 1/4" thick, 1" Square 1/8" thick, and 1/8th & 1/4" Flat Stock. There are 200-300 welds ea. (consuming 6 300ltr Argon bottles) and 1/3 of them the 1/4" and required the Full 250A from the machine. Worked like a charm....

Don't let anybody tell you the machine's not up to it!
