MMA
Hard to ignite arc
The arc ignition current is too low or the arc
ignition time is too short. Increase the arc ignition current or prolong the arc
starting time.
MMA
Excessive spatter or the
molten pool is too big. The arc ignition current is too high or the arc
ignition time is too long. Reduce the arc ignition current or shorten the arc
ignition time.
MMA
Normal arc cannot be
started. Input failure of the mains power supply or the
power cord is not well connected. Solve the input failure problem or reconnect the
power cord.
MMA
Electrode sticking The arc force current is too low. Increase the arc force current.
MMA
The electrode holder
becomes very hot. The rated current of the electrode holder is
lower than its actual working current.
Replace it with a higher rated current holder.
MMA
Arc is easy to break. Arc breaking voltage is too low. Increase the arc breaking voltage.
TIG
There is no current
output when pushing
the torch trigger.
Welding can be exited when the torch trigger is
pushed in some TIG operation modes.
Release the torch trigger and try again.
TIG
There is no current
output when pushing
the torch trigger.
The welding circuit is not in good connection.
Check the welding circuit, and reconnect it if
necessary.
TIG
There is no discharge
and arc cannot be
ignited when pushing
the torch trigger in HF
arc ignition mode.
The torch trigger is not connected. Connect the torch trigger.
TIG
There is no discharge
and arc cannot be
ignited when pushing
the torch trigger in HF
arc ignition mode.
The spark gap on the discharge board is too
big. Adjust the spark gap on the discharge board to
about 1.0mm.
TIG
The electrode burns
quickly in TIG welding.
The output polarity connection is incorrect. Exchange the polarity.
TIG
The electrode burns
quickly in TIG welding.
The cleaning strength is too big in AC mode. Reduce the cleaning strength.
TIG
Black weld bead
The weld bead is not well protected and is
oxidized.
Make sure the gas valve of the cylinder is open and
the pressure inside the cylinder is high enough.
Generally, it is necessary to refill the cylinder when
the pressure is lower than 0.5MPa.
TIG
Black weld bead
The weld bead is not well protected and is
oxidized.
Check if the gas flow is normal. You may select
different gas flow according different welding
current. However low the current is, the gas flow is
recommended to be not less than 5L/min.
Otherwise, the weld bead may not be fully covered
for lack of shielded gas.
TIG
Black weld bead
The weld bead is not well protected and is
oxidized.
Check if the gas path is air proof and if the gas is
pure enough.
TIG
Black weld bead
The weld bead is not well protected and is
oxidized.
Check if the environment is with strong wind.
