5-TROUBLE SHOOTING
Warning! An electric shock can be fatal. Before doing any work on the machine:
- Switch it off and unplug it from the mains
-
Put up a clearly legible and easy-to-understand warning sign to stop anybody
inadvertently switching it on again.
- Check to make sure the electrically charged components (e.g.capacitors) have
been discharged.
- Bolts in machine case also work for ground connection. Never use other bolt that
can not work for ground connection.
● Power source trouble shooting
Note! The flowing troubles and causes are uncertain. However, during the
process of MIG Pulse and the normal using conditions, that might happen.
NO. TROUBLE CAUSES REMEDY REMEDY
1 Power on indicator does
not light up, fan does not
run, no output when
machine switches on
1.Circuit breaker is damaged
2.No electricity on the
electricity grid
3. Short circuit in the power
supply cable
1.Check circuit breaker
and fan
2.Check power supply on
the electricity grid
3.Check the connection of
power supply cable
2 Power on indicator lights
up, but not Protection on
LED, and no output
1.Over-current protection
2.Ground cable is not well
connected to the work piece
3.Upper layer board is
damaged
1.Turn off the machine, and
turn on again after 1 minute
2.Check the connection of
ground cable
3.Replace
3 Circuit breaker trips
while welding
1.The following devices may
be damaged: MOSFET, output
diode module, etc
2.Pulse drive board is
damaged
3.Input rectifier bridge is
1.Check and replace
2.If MOSFET is damaged,
check if resistor (10Ω, 3KΩ),
and voltage regulator tube
(IN4148, 3V) are damaged
