Remove upper hole plug from rear panel.
Insert cord into opening in rear panel, and secure strain relief into opening.
8 Terminal Strip 1T
Connect voltage sensing lead to terminal strip 1TK at lead 42.
9 Voltage Sensing Lead
For constant current welding (CC), place jumper plug in the EXT position. Connect voltage sensing lead to workpiece.
For constant voltage welding (CV), place jumper plug in the INT position. Do not install voltage sensing lead.
10 Potentiometer R70
To adjust motor ramp speed, remove protective cap (if present), and adjust potentiometer R70 using a small nonconductive screwdriver. Rotating R70 clockwise increases the time it takes the motor to ramp up to speed.
