10. DIGIT AL OUTPUT METER: The digital output meters are located in the center of the control panel between the two large control knobs. The meters allow the output current level to be set prior to welding in stick mode and voltage level to be set prior to welding in the wire modes. During the welding process the meters display the actual output cu[...]

“WIRE WELDING” mode: In this mode increasing the number from 1 to 10 changes the arc from soft and washed-in to crisp and narrow . It acts as an induc- tance control. The proper setting depends on the appli- cation and operator preference. In general, MIG welding performs best in the “SOFT” range and Innershield in the “CRISP” range. EN[...]

Using your welder at low amperages with long idle run- ning periods during the break-in period may result in a glaze forming on the engine cylinder walls and the rings not seating properly . No amount of loading will properly seat the piston rings after they are glazed over . TYPICAL FUEL CONSUMPTION Refer to T able B.2 for typical fuel consumption[...]

CHOPPER TECHNOLOGY FUNDAMENT ALS The new era of welding machines such as the Commander 300, employ a technology whereby a DC source is turned on and off (chopped up) at high speed, then smoothed through an inductor to control an arc. Hence the name “Chopper .” The biggest advantage of the chopper technology is the high-speed control of the arc,[...]
