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.
QUICKGUIDE PI 200
5 Overheating indicator
The LED shines when the machine is
overheated.
4
6 Mains error
The LED shines if the mains voltage is too
1
high or too low.
7 Welding process
Choice of MMA/TIG.
24
8 Trigger mode
Choice of 2-stroke/4-stroke.
9 Current adjustment
8
Choice of internal/external adjustment.
10 Current adjustment
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.
I 250 I 350 I
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.
