If you haven't seen it yet the new AWS D1.1-2004 Structural Steel welding code has added power supplies requirements for FCAW and GMAW welding.
[blue]Section 3.2.4:
“3.2.4 FCAW and GMAW Power Sources. FCAW and GMAW that is done with prequalified WPSs shall be performed using constant voltage (CV) power supplies.” [/blue]
This is in the prequalification section so it does not prohibit the use of CC power supplies, it just requires users of CC power supplies to qualify their procedures by testing in accordance with Section 4 of the code.
