RECOMMENDATIONS
• ArcForce
Depending on the electrode type and the welding position, we recommend the following settings :
Arc Force
Rutile
Basic
Cellulosic
TIG WELDING WITH INERT GAS (TIG PROCESS)
CONNECTIONS AND RECOMMENDATIONS
Connect the earth clamp to the positive connector (+).
Connect the torch to the negative plug (–), the trigger cable and the gas hose. Ensure that the torch is equipped and ready to weld, and that the
consumables (Vise grip, ceramic gas nozzle, collet and collet body) are not damaged.
TIG WELDING PROCESSES
TIG DC STD
• TIG DC STANDARD
The TIG DC Standard process is recommended for high quality welding on most ferrous materials such as steel, stainless steel,,but also copper, copper
alloys, titanium...
The many settings for current and gas allow to fine tune any weldong operation, from the ignition to the cooling of the weld bead.
• TIG DC PULSE
The TIG DC Pulse is recommended for thin metal sheets or for certain materials. This mode alternates between hot and cold current, which reduces
the energy directed towards the workpiece
The settings are:
- The "I Cold" current is in percentage and sets up between 20% and 80% of the welding current.
The colder the current, the further it reduces the heat input during welding.
- The Pulse frequency (Hz Pulse) adjustable from 0.1 Hz to 2500Hz.
Thin sheets : Hz Pulse between 0.1 and 5Hz,
Downhand welding (PE): Hz Pulse between 5 and 20Hz,
Specific materials : Hz Pulse between 100 and 2500Hz,
The Pulse balance (%T_PULSE) is the % of cold current set up during a period (1: Period = 1/Hz Pulse)
Example:
The welding current "I" is set up at 100A..
I_Cold = 50%, which means = 50% of 100A = 50A.
Hz_Pulse is set up at 10Hz and %T_PULSE at 30%. The period of the signal will be at 1/10Hz = 100ms. The time of « I Cold » will be at 30% of this
period, 30ms.
