6Voltage 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 posi- tion. Do not connect voltage sens- ing lead.
To adjust motor ramp speed, re- move protective cap (if present), and adjust potentiometer R70 us- ing a small nonconductive screw- driver. Rotating R70 clockwise in- creases the time it takes the motor to ramp up to speed.
