• Plug the welding current lead plug (wire feeder) into the connection socket and lock by turning to
the right.
• Insert cable plug on the workpiece lead into the welding current socket “
” and lock by turning to
the right.
Some wire electrodes (e.g. self-shielded flux cored wire) must be welded using negative polarity.
Use the push-button for welding current polarity (pole reversal) to reverse the welding current
polarity (+/-) without having to swap the welding current leads. Signal lamps located above the
welding current sockets indicate the selected welding current polarity (+/-).
