MICRO DC 162/202
7.2 -TIG WELDING MODE
- Make the necessary connections to mains and earth as described in "Installation".
- Connect earth cable to positive plug by turning it firmly to right to assure a perfect electric contact.
- Connect TIG torch power cable to negative plug by turning it to right to assure a perfect electric contact.
- Connect gas tube to gas bottle. Check the content of gas bottle, and replace it, if necessary.
- Adjust gas flow 6 l/min and 12 l/min according to the value of the current.
- Apply a tungsten electrode on TIG torch. The electrode must be sharpening according the welding method: TIG DC
(tip sharpen).
- Turn the main switch on rear panel to ON position.
- The Power ON indicator lights, indicating that machine is under voltage.
- Select LIFTIG* (TIG welding with contact ignition). There is the PULSED welding mode available (both indicators are
lit respectively).
* LIFTIG:
6-close gas
1-open gas
2-contact
3- arc ignition
4-welding
5-stop
LIFTIG ignition (by contact) should be used when the high frequency radiations could disturb the functioning of
electronic devices near the welding zone (computers, pace-makers, medical tools, etc).
- Adjust welding current (Fig.1 - 3).
Pulsed LIFTIG welding – the welding current oscillates between a high and a low current value allowing less thermal
input in thinner plates and greater arc control.
- Ib - adjust welding base current in percentage of main current (the digital display shows Ib).
- UtH - WIDTH - adjust the time of the peak current (main current) from 10% to 90% (the digital display shows UtH).
- FrE - PULSE FREQUENCY - adjust pulsed current frequency in Hertz (the digital display shows FrE).
- Start welding.
