Caution! Do not tick against work piece; this could cause damage and hamper the lighting of
the bow. As soon as the bow lights, try to maintain the correct distance to the work piece
(corresponding to used electrode). The angle to your work piece should be 20-30°.
Caution! Always use pliers to remove used electrodes or to replace your work piece. Always
remember that the electrode clamp (1) must be put aside on an insulated surface! The slag
must only be removed after cooling down. When a weld is continued after stopping, the slag
at the end of it should first be removed.
7.3 Protection against overheating.
Your welder is equipped with an overheat protection. It protects the welding transformer for
overheating. When overheating occurs, the warning lamp (5) will light. Let your welder cool
down for a while.
