General Troubles and Problem Solving:
Trouble
Causes
Problem Solving
Power lamp not lit
1.No electricity input
2. Switch of welder fails.
1.Check incoming line
2.Replace the switch
Fan not rotating
1. Fan power line is off.
2. Enclosure blocks the fan due to distortion
3. The fan fails.
1.Reconnect the line
2.Reform the enclosure
3.Replace the fan
Warning lamp lights
1.Over heat (yellow lamp lights)
2.Over current (Green lamp lights)
1. Weld after cooling.
2. Increase input voltage
No output of welder
1.Over current protection
2. Welder fails
1. Over load using
2. Maintenance in manufacturer or service
center
Output current
decreased
1. Input Voltage is low
2. Input line is too thin
1. Power line is thickened
Current cannot be
regulated
1.Connecting line of the potentiometer is off
2.Potentiometer for current regulation fails
1.Reconnect the line
2.Replace potentiometer
High frequency arc
cannot be generated
1.The switch fails
2.Interval of high frequency discharging is
too big
3.Proximity of torch and work pieces too
great
4. High frequency
1.Replace torch switch
2.Regulate discharging interval to
0.8-1.0mm
3.Put torch tungsten electrode close to
material
4.Replace high frequency arc generator
Arc of argon welding is
broken or tungsten
electrode
is burnt
1.Argon gas flow is not regulated well
2.Tungsten electrode fails
3. Value of current does not match with dial.
of tungsten electrode
4.After flow time is too short
1.Regulate well
2.Replace or sharpen
3.Select the electrode dial and
current correctly
4.Increase the time
Welding torch
overheat
1. Cannot use the water cooling
when the current is more than
160A
2.The argon flow is the low current
1.Use water cooling
2.Increase the argon flow
