① Turn on the main power source, cooling water source and gas source, and check if they are in normal condition.

② Switch to “on” and the welding changeover switch to the “TIG” position (for manual/tungsten TIG welding dual-use power sources).

For AC/DC dual-use power sources, switch the mode switch to the intended mode. If impulse welding is performed, turn the pulse switch to pulse mode.

③ If the welding current attenuation function is required, the current attenuation switch should be switched to the “Yes” position. If not, switch to the “no” position.

④Adjust the welding current knob, attenuation time adjustment knob and gas lag time adjustment knob to the appropriate position, according to the intended welding parameters.

⑤ Turn on the gas check switch, adjust the argon gas flow rate to the desired value, and then turn off the gas check switch.

⑥Press the start button on the welding torch to weld.

⑦ When you finish working or leave the work site, you must turn off the power, water and gas sources.

It should also be noted that the argon gas cylinder should not be placed too close to the arc and should be placed at least 2m from the arc. It is best to fix the cylinder to prevent tipping.
