OPERATION INSTRUCTION
TIG Welding Description
1. Turn on the power switch of front panel, digital current meter is normal, fan begins to run.
2. Turn on argon switch, and adjust gas pressure to rated value.(refer to flow table).
3. Press switch of torch, electromagnetic valve is started. You will hear the sound of electricity-releasing HF sparkle and
at the same time, argon gets out the torch. NOTES: If the first time welding, you should press switch for a few
seconds before welding, until all the air in the gas passage is removed, and then start to weld. When you stop
welding, argon will still flow out for a few seconds, Which is designed to guarantee that weld spot is protected before
cooling down. So when the electric arc stops, keep the welding position for a while and then move the torch.
4. Choose the “pulse alter switch” according to the need. When the switch is on the down position, there is no pulse,
while between down and up position, there is middle frequency pulse (200Hz), while on the up position, there is low
frequency pulse 2Hz).
5. Adjust the switch of the Current Down Slope Adjustment according to the request of the work piece and welding.
6. Set suitable welding current according to the thickness of work piece and process demand.
7. Keep 2-4mm space between tungsten pole and work piece, press torch control switch, between electrode and work
piece HF electricity is released; After arc initiation, HF sparkle disappears soon and can start to work.
Sticking Description
1. Turn on the power switch on the front panel, and the fan begins to work.
2. Make sure function switch of front panel is on “down” position that is sticking. When welding jaw nips welding rod, it
begins to work.
3. According to work piece’s thickness, position, craftwork state, choose suitable welding current.
WARNING:
It is forbidden to pull out or put in the cable or connector during the process of welding, which will
threat life safety and damage the machine.
