OPERATION INSTRUCTION
DC TIG welding
1. Turn on power switch, fan begins to wheel.
2. Open argon switch, and adjust gas flow to rated standard.( refer to flow table)
3. Put the welding switch to
“upper position” is TIG WELDING.
4. When put the switch to
“DC” position, it is DC arc welding which can be for stainless steel, iron, copper
and other metals.
5. Set handwork/pedal switch according to needs. Put the switch to
“OFF” position, current is adjusted by
panel knob. Put the switch to
“ON” position, current is adjusted by pedal.
6. According to requirement to choose
“Pulse choosing switch”, “Down position” is no pulse. “Upper position” is
low frequency (0.5
—2Hz), and adjust the “Pulse adjustment knob” to suitable pulse frequency.
7. According to requirement to adjust the duty cycle to suitable position. ( When no pulse, value is 1 )
8. According to requirement to adjust arc initiation current and attenuation time.
9. According to thickness, set suitable welding current and basic value current (When pulse switch is down
position, no basic value current).
10. Press torch switch and electromagnetic valve starts, you will hear the sound of electricity-releasing HF sparkle
and at the same time, argon gets out the torch.
11. 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.
12. When finish welding, adjust the post-flow knob to suitable place in order to protect welding surface.
13. When TIG welding, for long welding and spot welding, you can choose the 2T/4T switch, when 2T,arc initiation
and down slope adjusting function can not work, only welding current works.
14. When 4T, press the torch switch is arc initiation current, releasing the switch is welding current, pressing again
is down slope time adjusting, releasing again is off working.
