OPERATION INSTRUCTION TIG WELDING DESCRIPTION

1. Tum on the power switch at the back panel, digital current meter is normal, fan begins to wheel
2. Open the valve of argon cylinder,adjust the volume of flow meter and make it is adequate to welding.
3. Press switch of torch,electromagnetic valve is started.Sound of HF arc striking can be heard,at the same time argon is flowing from torch burner NOTES: When welding is first operated,user must press switch of torch several seconds and beging to weld until all of air is be drained out. When welding is over, argon will still flow out in several seconds in order to protect welding spot before cooled down.So torch must be kept welding place some time before arc has been extinguished.
4. According to requirement to choose Pulse choosing switch \\\"Down position\\\" is no pulse :  Middle position is lF pulse : \\\"Upper position\\\' is low frequency(0.5 -2Hz), and adjust the \\\"Pulse adjustment knob to suitable pulse frequency
5. According to the thickness and processing techniques of workpiece under welding, adjust cument down slope time turnbutton
6. Set suitable welding current and make sure welding current is adequate to thickness of work piece and process demand.
7. It is 2-4 mm from welding tungsten electrode to work piece,press control knob of torch,burn and strike arc, sound of HF arc-striking will be diminished, The welding machine can be operated now.
