★ Adjusting the arc thrusting: Control the splash and steady arc. ★ Strong resistance for the fluctuate of the electricity 2.Main technical Data : MODEL EWELDM253 Voltage 1xAC220V 50Hz/60Hz INPUT Rated Input current 47.5A Rated Input power 11KVA No-load Voltage... - Page 6 ,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.
