I've been working with my new 210EXT, wow! Many options/ wave forms on AC ; not to mention pulse settings and a extensive frequency range. DC is also very adjustable, especially with DC Pulse and Frequency settings: 18 gauge SS is no problem now and it gets even easier to weld as you increase thickness of base materials.

I also received a email: my PowerCool W300 has shipped from EL! I'm looking forward to utilizing its benefits (the wonders of water!) with my TIG welders and enjoying extended practice sessions.
