Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the power source and properly set the feeder polarity switch.
N.A. Welding cables must be of proper capacity for the current and duty cycle of immediate and future applications.
N.B. Extend lead #21 using 14 AWG or larger insulated wire physically suitable for the installation. An
N.C. Tape up bolted connection.
N.D. Connect the control cable ground lead to the frame terminal markednear the power source terminal strip. The power source
grounding terminal (marked and located near the power source input power connections) must be properly connected to elec- trical ground per the power source Operating Manual.
N.E. Connect control leads t terminal strip as follows:
