Cause
Procedure
No power, signal failure or faulty
operation of the unit
No connection or loose plug inside the device
Check and correct connection of all electrical plugs
inside the device
No feed of the electrode wire (feeder
motor is running)
Weak pressure rollers
Set the correct pressure
Not the diameter of the groove of the guide
roller
Wear an appropriate guide roll
Contaminated guide wire holder Clean the guide wire electrode Locked wire electrode at the end of the current
Contaminated guide wire holder Clean the guide wire electrode Locked wire electrode at the end of the current
Replace contact tip
Irregular wire feed electrode
Current damaged tip
Replace contact tip
The groove the feeding roller is dirty or
damaged
Clean the roll groove or replace the roll
Spool with wire rubs against the walls of the lid welder
Attach the wire spool correctly
Not to bow strikes
Lack of proper contact wire clamp mass
To improve mass contact terminal
Faulty switch in the handle MIG
replace switch
Improper connection to the unit MIG
Check the condition of the electrical connections of the
handle, check that the pins in the socket are not broken
or jam
Arc too long and irregular
Welding voltage too high
Reduce the welding voltage
Wire feed speed too low
Increase the speed of wire feed
Arc too short
Welding voltage too low
Increase welding voltage
Wire feed speed too high
Reduce the wire feed speed
After power displays and LEDs are not lit.
No power supply
Check the fuses on the network connection
The fan is not working
The fan was blocked folded cover
Straighten fan cover
Unsatisfactory quality of the weld in MIG
Inadequate or poor quality materials or
consumables,
Replace consumables. Change the welding wire or the
gas cylinder for materials suitable or higher quality
Shielding gas flows from the wrong intensity.
Check the gas hose, improve the connection hose with
fittings and quick status check reducer Cylinder
Unsatisfactory quality of the weld MMA
electrode sticks to the work piece
Wrong polarity of welding cables
Connect the correct welding wires
Humid electrode.
replace electrode
Welder is supplied from the generator or by a long
extension cord diameter is too small cable
Connect directly to the mains
Unsatisfactory quality of the weld TIG welding
Check the quality of the materials and parts supplies,
especially tungsten electrode and a shielding gas
Replace consumable parts, replace the shielding gas
for higher quality
The shielding gas does not flow or flows of
insufficient intensity
Check Cylinder regulator, gas hose, improve the
connection hose with quick connectors, and status

Description
Overtemp
Protection against overheating. Wait a few minutes until it will cool down to a temperature enabling it again automatically activated. There should at
that time interrupt the power supply, since the continuously operating fan cools the heat sinks inside the unit to more quickly reduce the
temperature. After restarting, be sure to limit the welding parameters for further continuous operation.
