3.Function
3.1 Adjusting function for the welding voltage and welding current
3.1.1 EWELDM253 supply the adjusting range at MIG/MAG as following,
±
±
Welding voltage : 14V
3V~28V
3V use the voltage adjusting knob
Welding current : 20A~250A use the current adjusting knob
3.1.2 EWELDM253supply the adjusting range at MMA as following,
Welding current : 10A~250A use the welding current knob on the panel.
3.2 Adjusting function of the Arc thrusting
It has the important function to select the proper Arc thrusting for improvement of the welding
line ,control the welding splash and the steady Arc. Normally,.
If the thrusting is low ,the arc is soft and splash .
If the thrusting is high,the arc is strong and high splash.
Use the arc thrusting continuously by the control knob on the front panel of EWELDM253.
