Weld Gun and
Cable

1. Weld gun cable rolled up
or over curved

2. Adaptability of conductive
tip, wire feeding pipe and
cable diameter Worn,
blocked up or deformation,
etc.
〇 〇 〇 〇
Body of weld gun
 Loose connection of
conductive tip, nozzle and
nozzle contactor
 Contactor of weld gun body
is not plunged in or tightened
well
〇 〇
Power supply cable
of weld gun as well
as cable of switch
control

Break off (bending fatigue)

Damaged by weighted drop
〇 〇 〇 〇 〇
Surface Condition
of Parent material
and length that
wire stretches out

Oil, dirty, rust and paint
residues

Too long length of wire
stretched out
〇 〇 〇 〇 〇
Output Cable

Cross-section of cable that
connects to parent material
is not enough
 Loose connection of
（

output cable

Bad electric conductivity of
parent material
〇 〇 〇
Lengthened Cable
 Cross-section of cable is not
enough
 It is rolled up or folded
〇 〇 〇 〇
Work Condition for
Welding
 Welding current, voltage,
angle of weld gun, welding
rate and wire length
stretched out should be
confirmed once again
