[PSUBS-MAILIST] Welders

[Sean T. Stevenson via Personal_Submersibles]

Meaning I either need three phase service (cost prohibitive and often unavailable in residential areas anyway), or need an engine / generator driven machine? The multimatic claims to handle up to 3/8" material at its limited duty cycle. For the amount of time I would ever need to weld thicker material, I figure I could farm out those jobs. I wouldn't be comfortable doing my own pressure boundary welds in any case. I'm a designer, not a craftsman, and that seems like an appropriate time to engage a professional. I was just thinking structures and hobby projects (trailer frames) etc.

If the multiprocess machine won't perform to the published specs though, that's another matter entirely.
