Weld current starts when electrode
touches workpiece.
1 Electrode
2 Workpiece
3 Arc
Scratch Technique
Drag electrode across workpiece like striking
a match; lift electrode slightly after touching
work. If arc goes out, electrode was lifted too
high. If electrode sticks to workpiece, use a
quick twist to free it.
Tapping Technique
Bring electrode straight down to workpiece;
then lift slightly to start arc. If arc goes out,
electrode was lifted too high. If electrode
sticks to workpiece, use a quick twist to free
it.
