AC/DC control panel
1. Welding current/Arc voltage
Press the key and turn the control knob to
set the welding current. Press the key for
3 seconds to display the arc voltage (valid
ONLY for TIG DC and MMA DC). Press again
"A" to display the welding current.
2. Storage of programmes
Press the key and hold it down while turning
the control knob. When the key is released,
the selected programme space is activated.
3. Welding voltage
The LED shines when there is voltage on
MMA electrode or TIG torch.
4. Parameter units
The LED shines when the relevant parameter
unit is active.
5. Overheating indicator
The LED shines when the machine is
overheated.
6. Mains error
The LED shines if the mains voltage is too
high or too low.
4
7. Welding process
Choice of MMA/TIG.
1
8. Trigger mode
Choice of 2-stroke/4-stroke.
24
9. Current adjustment
Choice of internal/external adjustment.
10. Current adjustment
8
Choice of torch adjustment.
11. Ignition method
Choice of HF/LIFTIG ® ignition.
12. Gas pre flow (time)
13. Start amp
% of the set welding current.
14. Slope up
Time from start amp to welding current.
15. Slope down
Time from welding current to stop amp.
16. Stop amp
% of the set welding current.
17. Gas post flow (time)
18. Idle current
% of welding current. Press briefly in
4-stroke to activate a secondary current
value.
19. Pulse
Key activated = traditional pulse.
20. Pulse setting (traditional)
Press the menu key until the LED shines at:
Pulse time: Welding current period.
Pause time: Base current period.
Base current: % of pulse current.
21. Quick pulse
22. Pulse setting (quick pulse)
Press the menu key until the LED shines at:
Pulse frequency: Pause time + pulse time
Base current: % of pulse current.
23. Synergy PLUS™
Key activated = Synergy PLUS™.
Only mean current can be adjusted.
24. TIG-A-Tack + tack welding function
Key activated = TIG-A-Tack + tack welding
function and setting a tack-welding time
at key 27, allowing TIG-A-Tack welding =
almost invisible tacks.
25. Hotstart (MMA)
Start amp is briefly increased in % of the
welding current.
26. Arc Power (MMA)
Current is briefly increased during short
circuits.
27. Spot time
Time between slope up and slope down.
Tack/TIG-A-Tack time when key 24 is active.
28. Current type
Choice of AC or DC welding.
29. AC-t-balance, time-based
Time balance between positive and
negative half-wave is adjusted in %.

30. AC frequency
Setting of +/- frequency of the AC current.
31. AC-electrode preheating
Automatic electrode preheating.
32. AC-l-balance, amperage-based
The cleaning current of the positive half-
wave is adjusted in % in proportion to the
welding current of the negative half-wave.
33. Choice of secondary parameters
Opens parameters 12-18 and 27.
IGC (12+17)
If IGC (Intelligent Gas Control) is installed
(possible in Pi 350/500), the following
functions are available:
• Synergic gas flow relative to the set
current, if liter is set at less than 4 l
(please refer to the instruction manual
for any adjustment).
• Synergic gas post flow (time) relative to
the set current, if time is set at less than
0 second (please refer to the instruction
manual for any adjustment).
Using IGC requires an inlet pressure to the
welding machine of 1.5-6 bar from the gas
supply.
