Troubleshooting
After startup, the fan
does not turn or the wire
feeding speed is
abnormal
The air temperature is
too low or the fan is
damaged
If the temperature is too low, let the
machine work for a period of time, and the
standby temperature will rise, then fan will
rotate normally. If it is still not working,
replace the fan

(1) Ensure that the valve of argon cylinder
is open and there is enough pressure.
Generally, if the cylinder pressure is lower
than 0.5 MPa, it must be refilled.
(2) Check whether the argon flow rate is
normal. You can select the flow rate
according to the welding current condition,
but too low a flow rate may lead to
