Welding polarity change
This device permits welding of any welding wire on the market
thanks to the easy selection of the welding polarity (direct or
reverse).
Reverse polarity: the power cable from the torch (21) must be
connected to the positive pole (+) (22) of the terminal strip. The
power cable from the earth socket (23) must be connected to
the negative pole (-) (24) of the terminal strip.
Direct polarity: the power cable from the torch (25) must be
connected to the negative pole (-) (26) of the terminal strip. The
power cable from the earth socket (27) must be connected to
the positive pole (+) (28) of the terminal strip.
Before shipment, the equipment is set for use with reverse
