PI Plasma control panel
Fast pulse
Is used for selection of fast pulse.
The pulse current is equal to the set
current. It is possible to adjust:
Pulse frequency
For TIG DC/Plasma welding the range is 25-988 Hz
and for MMA DC welding the range is 25-100 Hz.
Base amp
Adjustable from 10 to 90% of the pulse current.
Synergy PLUS
TM
The machines automatically and dynamically adjust
all overall pulse parameters during welding, when
the peak welding current has been set by encoder.
TIG tack welding TIG-A-TACK
TM
The machine offers one tack welding function in
the individual program to allow quick switch-over
from welding to tack welding. In TIG DC and Plasma the
following features will be available:
- Arc ignition HF 2-times
- No slope-up/slope-down
- No pulse
- Reuse of pre-gas/post-gas values from the current
program
- Spot TIME from 0.01 to 2.5 secs in steps of 0.01 sec. Set
the value by selecting the parameter “spot time” .
Torch adjustment/remote control –
7-poled plug
The regulation of welding current is made by
means of the torch potentiometer (optional).
The maximum current reachable is the level previously
adjusted on the front panel. The minimum current is 5A.
External adjustment – 8-poled plug (optional)
Can be used for foot pedal (optional) and remote
control units (optional) that use a 8-poled plug.
The function is used for adjustment of the current.
The maximum current reachable is the level previously
adjusted on the front panel. The actual current is shown
on the display.
Ignition methods
It is possible to choose between 2 different
methods of ignition for TIG welding: High-
Frequency (HF) and LIFTIG ignition. The ignition method
cannot be changed during welding. The LIFTIG ignition
is active when the indicator is illuminated. The HF is
automatically active when the LED is switched off. A third
option permits the use of a TIG torch without trigger:
LIFTIG without TRIGGER.
HF-ignition (TIG and PLASMA welding)
In HF-TIG ignition the eletrode should not touch the
workpiece. A high-frequency (HF) impulse initiates the arc
when the torch trigger is activated.
The HF will not arise and the machine will stop if the
electrode is in contact with the workpiece. Detach the
electrode and start ignition again
LIFTIG-ignition (only TIG)
In LIFTIG ignition the TIG arc is ignited after making
contact between the workpiece and the tungsten
electrode, after which the trigger is activated and the arc
is established by lifting the electrode from the workpiece.
LIFTIG-ignition without Torch trigger (TIG)
This operation offers the possibility of using TIG torches without
trigger: turn ON the arc by touching the workpiece with the
electrode and lift the torch to ignite the arc. To activate the
operation keep pressed for 3 seconds the keypad “trigger
mode”: the relative led flashes on and off to indicate the new
function. Turn OFF the arc by removing the torch from the
workpiece.
Trigger mode
Selection of trigger mode. Four-times trigger mode is
active when the LED is illuminated, and two-times trigger
mode is active when the LED is turned off. It is not possible to
change trigger method during the welding process.
Two-times
The welding process begins by pressing the torch trigger.
Welding continues until the trigger is released again which
effects the slope-down period. It is possible to configure the
machine to work in 2 different ways when this mode is selected.
For detailed information read the section “USER MENU” conc.
“2t.o.”
Four-times (only TIG)
The welding process begins by pressing the torch trigger. If the
torch trigger is released during the slope-up period welding
continues with the adjusted welding current. In order to stop
the welding process the trigger must be pressed again for more
than 0.5s after which the slope-down period begins. The slope-
down period can be stopped by releasing the trigger. Thereafter
the post-flow starts. It is possible to configure the machine to
work in 3 different ways when this mode is selected. For detailed
information read the section “USER MENU” conc. “4t.o.”
Reset to factory settings of all programs
It is possible to recall all factory standard
parameters. In this case all programs in the
machine will be reset to the following value:
• MMA current 80A
• MMA hotstart 50%
• MMA arc power 50%
• TIG Current 80A
• TIG Spot Current 80A
• Plasma current 80A
• Plasma pilot arc 10A
• Plasma gas 3.0 liters
• Plasma gas slope down 0 sec.
• Plasma gas final value 0.1 liters
• Shield gas 3.0 liters
• Pre-flow 0.0 sec
• Post-flow 3.0 sec
• No slope-up/slope-down
• Start amp 40%
• Stop amp 20%
• Second Current level 50%
• Base amp 40%
• Fast pulse frequency 49Hz
• Pause time = Pulse time = 0.1 sec
• Cooling method = 1 (external cooling)
The reset procedure is as follows:
Switch off the machine and wait until display is extinguished.
Press the following key pads simultaneously:
Switch on the machine and keep the above keys
pressed until the display shows “X.XX”. Then release the keys.
X.XX is the software version of program.
