Weld current starts when electrode
touches workpiece.
Weld current can damage elec-
tronic parts in vehicles. Discon-
nect both battery cables before
welding on a vehicle. Place work
clamp as close to the weld as
possible.
F
Always wear appropriate personal pro-
tective clothing.
1 Workpiece
Make sure workpiece is clean before
welding.
2 Work Clamp
Place as close to the weld as possible.
3 Electrode
Before striking an arc, insert an electrode in
the electrode holder. A small diameter elec-
trode requires less current than a large one.
Follow recommendations of the electrode
manufacturer when setting weld amperage
(see Section 12-2).
4 Insulated Electrode Holder
5 Electrode Holder Position
6 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.
Correct arc length is related to electrode di-
ameter. Examine the weld bead to determine
if the arc length is correct.
Arc length for 1/16 and 3/32 in. diameter
electrodes should be about 1/16 in. (1.6
mm); arc length for 1/8 and 5/32 in. electro-
des should be about 1/8 in. (3 mm).
7 Slag
Use a chipping hammer and wire brush to re-
move slag. Remove slag and check weld
bead before making another weld pass.
