STICKING DESCRIPTION
1
）
It is 2-4 mm from welding tungsten electrode to workpiece, press control knob of torch, burn
and strike arc, sound of HF arc-striking will be diminished. The welding machine can be
operated now.
2
）
Open power switch of front panel, fan is beginning to work.
3
）
Make sure function switch of front panel is on “down” position that is sticking. Impulse
changeover switch and knob of current down-slope time will not work.
4
）
Make sure welding current is adequate to thickness of work piece.
