13-1. Stick Welding Procedure
stick 200704 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.
1 Workpiece
Make sure workpiece is clean be-
fore welding.
2 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 13-2).
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.
7 Slag
Use a chipping hammer and wire
brush to remove slag. Remove
slag and check weld bead before
making another weld pass.
