B-5 OPERA TION B-5 NOMINAL PROCEDURES The Power Wave is designed to operate with 3/4" electrode stick-out for CV and Pulse processes and a 1/2" stick-out for STT processes. FRINGE PROCEDURES Excessively short or long electrode stick-outs may function only on a limited basis, if at all. MAKING A WELD The serviceability of a product or stru[...]

B-6 OPERA TION B-6 • VOLTS / TRIM: In constant voltage modes (synergic CV, standard CV) the control adjusts the welding voltage. In pulse synergic welding modes (pulse GMAW only) the user can change the Trim setting to adjust the arc length. It is adjustable from 0.500 to 1.500. A Trim set- ting of 1.000 is a good starting point for most condi- t[...]

B-7 OPERA TION B-7 CONST ANT VOL T AGE WELDING Synergic CV : For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special soft- ware at the factory. The nominal preprogrammed volt- age is the best average voltage for a given wire feed speed, but may be adjusted to preference. When the wire feed speed changes, [...]

B-8 OPERA TION B-8 PULSE WELDING Pulse welding procedures are set by controlling an overall "arc length" variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, back ground current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed [...]

B-9 OPERA TION B-9 STT WELDING The pictures illustrate the waveshape of current for the process. They are not drawn to scale, and are intended only for the purpose of showing how the vari- ables effect the waveform. Trim in the STT mode adjusts the tailout and back- ground portion of the waveform. For open root processes, the tailout is fixed, and [...]
