Some wire electrodes (e.g. self-shielding cored wire) are welded using negative polarity. In this
case, the welding current lead should be connected to the "-" welding current socket, and the
workpiece lead should be connected to the "+" welding current socket. Observe the information
from the electrode manufacturer!
