MIG/MAG cored wire welding: Workpiece connection
• Insert the plug on the workpiece lead into the "-" welding current connection socket and lock.
• Attach and then lock the plug of the welding current lead (wire feeder) to the „+“ connection socket.
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!
