B-1 OPERA TION B-1 GENERAL DESCRIPTION The Invertec V250-S is a 250 amp arc welding power source that utilizes single or three phase input power, to produce constant current output. The welding response of this Invertec has been optimized for stick (SMAW) and TIG (GTAW).
B-2 OPERA TION B-2 1. Power Switch - Place the lever in the “ ON ” position to energize the machine. When the power is on, the fan will operate and the output will be energized in SMAW modes. GTAW mode requires remote trigger to energize the output.
B-3 OPERA TION B-3 6. Arc Force - This control functions in SMAW modes to adjust the Arc Force. The arc is soft at the mini- mum settings and more forceful or driving at the maximum settings. Higher spatter levels may be present at the maximum settings.
B-4 OPERA TION B-4 P ARALLEL OPERA TION The Invertec ’ s are operable in parallel. For best results, the currents of each machine should be rea- sonably well shared.
