within 1s, which can reduce the tungsten spoilage farthestly，prolong the using life of the tungsten
electrode，and prevent tungsten clipping.
○ 3 MMA operation： if the electrode touches workpiece over two seconds, the welding current will drop
to the 0 automatically to protect the electrode.
Prevent arc-break function：TIG operation，Avoid arc-break with special means, even if arc-break occurs
the HF will keep the arc stable
④TIG：If the TIG torch is pressed quickly, the welding current will drop a half, then if the TIG torch is
pressed quickly again, the welding current will get back.
Notices:

Check the condition of welding and connection units firstly, otherwise there will be malfunction such
as ignition spark、gas leakage、out of control and so on.

Check that whether there is enough Argon gas in the shield gas cylinder, you can test the
electromagnetic gas valve through the switch on the front panel.

Do not let the torch aim at your hand or else of your body. When you press the torch switch, the arc
is ignited with a high-frequency, high-voltage spark, and the ignition spark can cause interferences in
equipment.

The flow rate is set according to the welding power used in the job. Turn the regulation screw to
adjust the gas flow which is shown on the gas hose pressure meter or the gas bottle pressure meter.
● The spark ignition works better if you keep the 3mm distance from the workpiece to the tungsten
electrode during the ignition.
Note: When select AC output, the current and the wave form are as same as the above, but output
polarity changes alternately.
