cable (21 of Drawing 483A756). This cable should be connected to the Electrode
(Positive) terminal on the welder. Also, connect a #2 or larger welding cable from
the Work (Negative) terminal to the work ground.
Gun Control Connections
Plug the control cable (14 of Drawing 483A756) into the gun control receptacle on the
control, making sure that the plug is fully engaged.
