The protection grade of 410-PROTIG20
Welder is IP21S. It is forbidden to put in a finger or insert a round bar less than
12.5mm (metal bar in particular) into the welder. No heavy force can be employed on the
welder.The former board schematic diagram

Attention
：
* Welding machine continuous work time is too long, the protection of the panel light is bright, show that the
temperature of the welding machine internal temperature rise has been more than design value, use after period of
time shall be suspended at this time (standby inner cooled down, while protecting the lights go out) may continue to
use
；
* Work done or temporary leave welding on site, should shut off the power switch and argon gas valve
；
* Welders should be worn denim overalls and welding mask, in order to prevent the arc and thermal radiation
；
* Job site should be placed around the screen, to prevent others affected by the arc
；
* Operations shall not be placed near the site flammable items
；
* Welder each interface must be accurate and reliable connection
。
Welding basic steps
*
TIG welding

Before welding modulation
Set the p Set the press of a welding torch switch, argon gas flow
。
The welding mode selection switch when placing in the argon arc welding can use argon arc welding
。
According to the needs of welding specification: adjust welding current adjustment knob, adjustment of welding
current
。
b
）
No-load running and function
The press of a welding torch switch, send out airflow, at the same time to hear the voice of the machine with high
frequency pulsed arc discharge; Open the switch after discharge to immediately stop, air valve delay 2 seconds or stop
to aspirate after 4 seconds

TIG welding
Pick up the torch, weld, the press of a welding torch switch, can ignite arc argon arc welding

Modulation and functional confirmation before welding
The welding mode selection switch when placing in manual arc welding can be used as a manual electric arc
welding
。
According to the needs of welding specification adjustment welding current adjustment knob Set the welding
current
