 t4～t5： Post flow time, adjustment range of post flow time: 0.0～10.0S;
 t5： Electromagnetic valve is closed and stop argon flowing. Welding is finished.
Short circuit protect function：
(1) TIG /LIFT：If the tungsten electrode touches the workpiece when welding, the current will drop to
5A, which can reduce the tungsten spoilage，prolong the using life of the tungsten electrode and
prevent tungsten clipping.
(2) TIG /HF：If the tungsten electrode touches the workpiece when welding, the current will drop to 0
within 1s, which can reduce the tungsten spoilage，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.
(4) Prevent arc-break function：TIG operation， Avoid arc-break with special means, even if arc-break
occurs the HF will keep the arc stable.
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
