TIG welding
PREPARATION FOR WELDING
Cleaning before welding
TIG welding is very sensitive to surface contamination of the metal. Because of that, before the welding process must be removed from the
surface of the welded lubricants, paints, coatings and oxidized.
Welding - arc ignition (touch)
1)
Welding starting end should touch the surface of the tungsten electrode welded, by pressing the trigger in the handle TIG and
increasing the distance 2-3mm will touch arc ignition (LIFT ARC)
2) The value of the welding current is increased to a set value
2) The value of the welding current is increased to a set value
3)
We raise and rotate the handle to the normal working height
4)
Completion of the work takes place by lifting the handle until the extinction of the arc

symptoms
Cause
Procedure
The yellow LED lights up
The voltage is too high (≥15%)
Turn off the power, check the installation and restart the welder
when the supply voltage is in the proper condition
The voltage is too low (≤15%)
Poor ventilation thermal protection
Increase ventilation
Too high temperature circuit
Indicator automatically turns off when the
temperature decreases
Using more than the recommended load
Lack of a wire (feeder motor is
running)
For poorly tightened pressure
Tighten the clamp correctly
Contaminated guide wire holder
Clean the wire guide
A predetermined groove roll does not correspond to the
diameter of the wire
Brought into line with the roll diameter and wire
Blocked the wire in the nozzle current
Replace the current nozzle
No wire feed (feed motor not
running)
Damaged engine
Pass the welder to the site
Faulty control system
Pass the welder to the site
Irregular wire feed
Current defective nozzle
Replace the nozzle current on new
The groove feeding roller is dirty, damaged
or not the diameter of the wire
Replace the roll or roller to choose the diameter of the
wire used
Not to bow strikes
Lack of proper contact wire clamp
mass
Improve contact terminal
Arc too short
Welding voltage too low
Increase welding voltage
Wire feed speed too high
Reduce the wire feed speed
Arc too long and
irregular
Welding voltage too high
Reduce the welding voltage
Wire feed speed too low
Increase the speed of wire feed
