General Troubleshooting - gala gar Smart Tig 310 PACDC Manual Técnico De Instrucciones

The following operation requires sufficient professional knowledge on electric aspect and comprehensive safety
knowledge. Operators should be holders of valid qualification certificates which can prove their skills and
knowledge. Make sure the input cable of the machine is cut off from the electricity utility before uncovering the
welding machine.

8.1 General troubleshooting

The phenomena listed blow may be caused by the accessory and gas you use, the working
environment or the power supply condition. Try to improve the working environment to avoid
such occurrences.
Phenomena
The fan does not work or it
works abnormally.
Hard to ignite arc
Excessive spatter or
the molten pool is too
big.
Normal arc can not be
started.
Electrode sticking
The electrode holder
becomes very hot.
Arc is easy to break.
There is no current
output when pushing
the torch trigger.
There is no discharge
and arc cannot be
ignited when pushing
the torch trigger in HF
arc ignition mode.
The machine may be damaged during welding. Timely maintenance should be carried out after
the confirmation of damage. Only qualified individuals can uncover or repair the machine.
Otherwise, further machine fault and further damage to valuable parts may occur.
To facilitate the maintenance of the welding machine, the wiring diagram of this machine is
provided on the next page for your reference.

Electric shock can cause personal injury or even can kill.
Cause
The 3-phase power cord is not well
connected.
Phase failure
The mains voltage is overly low.
The arc ignition current is too low or
the arc ignition time is too short.
The arc ignition current is too high or
the arc ignition time is too long.
Phase failure of the mains power
supply or the power cord is not well
connected.
The arc force current is too low.
The rated current of the electrode
holder is lower than its actual working
current.
Arc breaking voltage is too low.
Welding can be exited when the torch
trigger is pushed in some TIG
operation mode.
The welding circuit is not in good
connection.
The torch trigger is not connected well.
The spark gap on the discharge board
is too big.
WARNING
Reconnect the 3-phase power cord.
Solve the phase failure problem.
Welding can be carried out after the mains voltage
recovers.
Increase the arc ignition current or prolong the arc
starting time properly.
Reduce the arc ignition current or shorten the arc
ignition time properly.
Solve the phase failure problem or reconnect the
power cord.
Increase the arc force current properly.
Replace it with a higher rated current.
Increase the arc breaking voltage.
Release the torch trigger and try again.
Check the welding circuit, and reconnect it if
necessary.
Connect the torch trigger well.
Adjust the spark gap on the discharge board to
about 1.0mm.
