Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the power source, position the positive - negative switch on power source to correspond to the polarity of the electrode cable connection.
N.A. Welding cables must be proper capacity for the current and duty cycle of immediate and future applications.
N.B. Extend lead #21 using #14 or larger insulated wire physically suitable for the installation. an S16586 remote voltage sensing work lead is available for this purpose. Connect it directly to the work piece keeping it separate from the welding work cable connection to work piece. For convenience, this extended #21 lead should be taped along the welding work cable. (This extended #21 lead connection replaces the need to employ the remote work lead accessory on any
N.C. Tape up bolted connection.
