It may cause splash. Please replace
the damaged one.
It may cause bad gas-shield, defect
of welding or burning of welding
torch and so on. Please handle it
properly.
Remark
Cause of instable wire-feeding or instable arc.
Clean the fragment. Find out the cause and
rectify it.
Cause of instable arc, welding wire fragment
or powder.
The inconsistence of them may cause
welding wire powder and instable arc.
1.It causes wire power, jam of wire feeding
tube and instable arc.
2.replace it if unusual phenomenon is found.
It causes bad wire-feeding.
Furthermore it causes instable arc.
Remark
1.Casue of bad wire-feeding
2.Too much wire feeded with bent cable
may cause instable arc. So please
straighten it while welding.
Proper measures of inspection shall be
used for body safety and welding stability.
Usual inspection-general and simple
Regular inspection-thorough and
