SECTION 14 − STICK WELDING (SMAW) GUIDELINES
14-1. Stick Welding Procedure
stick 2008−05 − ST-151 593
! 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.
1 Workpiece
Make sure workpiece is clean be-
fore welding.

Work Clamp
3 Electrode
A small diameter electrode re-
quires less current than a large
one. Follow electrode manufactur-
er’s instructions when setting weld
amperage (see Section 14-2).

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.
7
Slag
Use a chipping hammer and wire
brush to remove slag. Remove
slag and check weld bead before
making another weld pass.
