OPERATION - TIG
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
TIG welding mode
Terms used: TIG – Tungsten Inert Gas, GTAW – Gas Tungsten Arc Welding.
TIG welding is an arc welding process that uses a non - consumable tungsten
electrode to produce the heat for welding.
The weld area is protected from atmospheric contamination by a shielding gas
(usually an inert gas such as argon or helium) and a filler rod matching the
base material is normally used, though some welds, known as autogenous
welds, are carried out without the need for filler wire.
The Jasic 200CS when used in Lift TIG mode can accommodate the use of a Euro style TIG torch.
Connect the TIG torch to the (MIG) Euro connector.
Ensure the trailing lead is connected into the “ - ”
socket on the front panel of the machine and fully
tightened clockwise.
Insert the cable plug for the work clamp into the “+”
socket on the front panel of the welding machine
and fully tightened clockwise.
Connect the gas hose to the regulator/flowmeter
located on the shield gas cylinder and connect the
other end to the machine.
Before starting any welding activity ensure that you have suitable eye protection and protective
clothing. Also take the necessary steps to protect any persons within the area.
Now you will need to switch the power switch on the back panel to “ ON ” and then select TIG mode by
switching the welding mode dial to TIG.
Set the amperage on the machine suitable for the application and tungsten being used. (see below guide).
Ensure you have adequate welding current according to
the thickness of the work and weld prep being carried
out and filler wire being used.
Open the gas valve of the cylinder, press the torch trigger and adjust the gas regulator to obtain the
desired flow rate.
Once welding is complete release the torch trigger switch which will stop the welding arc but ensure you
leave the torch in place to shield the weld with gas for a few seconds until the preset post flow gas turns
off.
