Weld current starts when

electrode touches work-

piece.

Weld current can damage

electronic parts in vehicles.

Disconnect both battery

cables before welding on a

vehicle. Place work clamp

as close to the weld as

possible.

.

Always wear appropriate per-
sonal protective clothing.

Arc Length

Arc length is the distance from the

electrode to the workpiece. A short

arc with correct amperage will give

a sharp, crackling sound.

brush to remove slag. Remove
