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 DC pulse operation steps (continued)
To select welding current, rotate the dial until the peak amps
LED is lit, then press the dial and the LED will then start to flash,
by rotating the adjustment control dial will adjust the welding
current shown in the display window. Range is 5 ~ 200 amps.
The next step will allow setting of the base current. This function is only allowed when the pulse mode is
selected.
To select background current, rotate the dial until the base amps
LED is lit, then press the dial and the LED will then start to flash,
by rotating the adjustment control dial will adjust the base
current shown in the display window. Range is 5 ~ 200 amps.
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, by rotating the adjustment control dial will adjust
the pulse frequency rate between 0.5Hz to 200Hz.
To select and set pulse ratio (width), rotate the dial until the
pulse % LED is lit, then press the dial and the % LED will then
start to flash, by rotating the adjustment control dial will
adjust the pulse ratio rate between 10% ~ 90% .
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 start to 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 welding arc stops with gas still flowing for the pre - set post flow time and welding ends.
