4.2 Welding current adjustment

GM series welder has the function of welding current pre-setting. Before welding,
adjusting welding current, the welding current display will show the ampere. It is
convenient to set parameters and adjust accurately.

4.3 Welding operation

4.3.1 Striking arc way
Knocking arc: take the electrode upright to touch the workpiece, after forming short circuit, quickly lift up
about 2~4 mm, and arc will be ignited. This method is difficult to master. But in the welding for the brittle
or hard steel, it is better to use knocking way.

Lifting arc: take the electrode to scrape the workpiece for striking arc. But it may cause the arc
scratch, so must to lift arc in the groove.
