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). OPERA TIONAL FEA TURES The Invertec V250-S provides continuous total range out[...]

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. 2. Output Control - This controls the output current. Control is provided over the entire 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. 7. Output Terminals - These quick disconnect termi- nals provide connection points for the elect[...]

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. As an example, with two machines set up in parallel for a 300 amp procedure, each machine should be set to deliver approximately 150 amps, not 200 amps from one and 100 amps from the[...]
