2 、 Troubleshooting
Reason Remedy
No welding output
( 1 ) Connected power supply
incorrectly .
(2) Power switch in " off "
position
（1） C o nnect power supply according
to manufacturer’s instructions .
（2）
P
lace power switch in “on”
position .
Trigger not working
（1） Trigger damaged .
（2） Gun control wire broken .
（3） Control wire plug loosen .
( 4 ) Mode switch in incorrect
position .
（1） Replace trigger .
（2） Connect again or replace if nec-
essary .
( 3 ) Connect control wire plug again .
( 4 ) P l ace Mode switch in correct pos-
ition .
(1)Aamperage too low
(2) Weld time too short .
(3) Input power cord did not
meet the requirement .
(4) Ground clamp bad contact .
(
1)
Increase amperage setting
(2) Increase time setting .
(3) Replace input power cord .
(4) Change ground clamp location .
Piercing workpiece
( 1
)
Output amperage too high .
(2) Weld time too long .
(3) Bad contact of electrode tip or
washer with workpiece .
(1) R educe amperage setting .
(2) Rrduce weld time .
(3) Remove coating from material
reduce added pressure .
Carbon rod working
unstable
( 1)Carbon rod or workpiece is dirty
(2) Incorrect amperage and time
setting .
( 1)Polish carbon rod and
workpieces before welding
(2) Set amperage and time according to
workpiece thickness .
Welder stop w o rki n g
while ope ra ti on
(1)Trigger plug loosen .
(2) Gun control wire broken .
(3) Over heating .
(1)Check gun control wire and
trigger plug .
(2) Wait for temperature cool down .
