Intermediate hose package connection
NOTE
Note the polarity of the welding current!
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!
