PEAK TIME
Time for which the current pulse is at the maximum value.
Consequences of a higher value:
-
Greater weld penetration.
- Facility to make deeper cuts.
Consequences of a lower value:
-
Reduction of heat-affected zone.
- Difficult to create a weld pool.
PULSED CURRENT FREQUENCY
Consequences of a higher value:
-
Slower melt speed.
- Reduction of heat-affected zone.
BASE TIME
Time during which current output is at the base value.
Consequences of a higher value:
-
The filler material is spread more evenly.
- Increase of heat-affected zone.
DOWN SLOPE
Time during which the current changes from the welding value to the
end value by means of a slope.
FINAL CURRENT
During electrode welding the parameter makes it possible to obtain a
uniform deposit of filler material from the start to the end of the
welding process, closing the deposition crater with a current such as
to deposit a final droplet of filler material.
By keeping the torch trigger pressed during the 3rd time, the crater
filler current is maintained thereby ensuring optimal crater filling, until
the post gas time is started by releasing the torch trigger (4th time).
POST GAS TIME
Time of post gas delivery when the welding arc is extinguished.
Consequences of a higher value:
-
More effective pickling (improved appearance of workpiece at the
end of the welding pass).
- Higher gas consumption.
Consequences of a lower value:
-
Lower gas consumption.
- Oxidation of electrode tip (more difficult arc strike).
VRD
This parameter reduces the potential across the welding sockets
when welding is not in progress.
The arc strike procedure is as follows:
- Touch the workpiece with the electrode tip.
- Raise the electrode.
- Power is released for several seconds.
- Touch the workpiece with the electrode tip.
- The welding arc will strike.
LONG ARC VOLTAGE
This parameter inhibits power output when the potential between
electrode and workpiece exceeds the preset threshold level.
Consequences of a higher value:
-
The welding arc persits even with a significant distance between
the electrode and the workspiece.
- Consequences of a lower value:
- Faster exit from weld.
REMOTE CONTROL ACTIVATION
This parameter enables the unit to receive the current reference
signal from a remote control.
SPOT TIG TIME
When the torch trigger is pressed the welding arc persists for the time
set in the parameter.
Press the torch trigger again to resume the welding process.
The result of this is a very precise, not oxidized welding spot without
any plastic deformation of the sheet.
HF ARC START
This parameter enables the arc strike in the TIG welding procedure by
means of a high frequency (HF) current discharge.
The high frequency arc strike (HF) prevents the inclusion of impurities
at the start of the weld pass.
WARNING: The high frequency arc strike (HF) can harm electronic
boards when welding is performed on equipment that incorporates
such devices.
MINIMUM PEDAL CURRENT
Minimum output current value with foot pedal controller external
reference.
The current is set as a percentage with respect to the "maximum foot
pedal current" parameter.
AC WAVEFORM
This parameter allows selection of the required AC waveform.
AC WAVEFORM CHARACTERISTICS
Sine Low noise
Square
High noise
Greater penetration
Reduced pickling
Sawtooth Medium noise
Q-START
This parameter allows the unit to start in synergic pulsed TIG mode
for the preset time interval, before switching automatically to the
welding procedure selected on the interface panel.
The parameter creates a weld pool faster with respect to the standard
starting procedure.
This parameter is useful when spot welding thin gauge sheet.
DYNAMIC ARC
Welding power remains constant even when the distance between
electrode and workpiece changes.
Consequences of a higher value:
- The welding arc concentration remains unchanged.
- Prevents electrode sticking.
- Thin workpieces may become deformed more easily.
MULTI TACK
This parameter allows thin gauge sheet to be welded without
deformation.
Consequences of a higher value:
- Welding of thinner gauge sheet without deformation.
- Less melting of material, slower welding process.
