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 AC pulse operation steps
To select and set TIG pulse frequency, rotate the dial until the pulse Hz LED is lit, then press the dial and
the Hz LED will then start to flash, then
rotating the adjustment control dial will
adjust the pulse frequency rate between
0.5Hz to 25Hz in AC mode.
To select and set pulse ratio (width), rotate the dial until the pulse %z LED is lit, then press the dial and the
% LED will then start to flash, then rotating
the adjustment control dial will adjust the
pulse ratio rate between 5% ~ 95% in AC
mode.
Please Note:
The parameter lit LED will always default back to the peak amps setting when no other control have
been touched after approximately 2 seconds.
After the parameters are set appropriately, open the gas valve of the cylinder and adjust the gas regulator
to the desired gas flow.
Keep the torch 2 - 4mm away from the work piece and then press the torch trigger.
Gas will flow followed by the HF and the arc is ignited.
Once the arc is ignited the HF will cease and the current rises up to the pre - set value and welding can be
carried out.
After releasing the torch trigger, the current begins to decrease automatically to the crater current value,
the arc will then stop with gas still flowing for the post flow time and the welding process ends.
