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 from control cable with terminal strip connectors or from
remote voltage sensing work lead may be ordered for this purpose.
Connect it directly to the work piece keeping it electrically separate from the welding work lead circuit and connection. For convenience, this extended #21 lead should be taped to the welding work lead. (If the length of work lead circuit is
short, and connections can be expected to be reliable, then control cable lead #21 does not need to be extended and can be directly connected to terminal #21 on the terminal strip. Note that this is not the preferred connection because it adds error to the
N.C. Tape up bolted connection if lead #21 is extended.
N.D. Connect the control cable ground lead to the frame terminal
marked near 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 electrical ground per the power source operating manual.
N.E. The jumpers on the

N.F. If lead #21 is to be connected to the terminal strip, connect to the #21 terminal that matches work polarity. This connection must be changed
whenever the electrode polarity is changed.
