It controls the balance between cleaning and penetration to achieve the best balance or desi-
red effect while welding in the AC mode. More EN means better penetration, more EP means
better cleaning. Too much of EN may result not enough cleaning action, too much of EP may
result increased electrode consumption.
When EN equals 50% there is equality between EN and EP. When value of EN is more than EP
we call it “negative balance” when EN is less than EP we call it “positive balance”.
For most welds the optimal value is between 60-70% of EN value.
7.7.5 Course of TIG welding process – 2T
During TIG function 2T, you can not set the current parameters of the initial and final current.
0
Press the gun switch and hold it. Electromagnetic gas valve is turned on.
The shielding gas stars to flow.
0-1
Pre-gas time.
1
Initiation of the welding arc.
1-2
The rise time of the welding current.
2
Achieving the set value of welding current.
2-3
During the whole welding process, the gun switch is pressed and held without releasing.
3
Release the gun switch, the welding current will drop in accordance with the selected
down-slope time.
3-4
The current drops to the minimum welding current from the setting current,
and then arc is turned off.
4
Termination arc welding.
4-5
Post-gas time, after the arc is turned off. You can adjust it (0.1~10s) through turnning
the knob on the front panel.
5
Electromagnetic valve is closed and stop argon flowing. Welding is finished.
