TIG WELDING PROCESSES
• Standard
The Standard TIG mode provides high quality welding on most ferrous materials
such as steel and stainless steel, but also on copper and its alloys, and KRYPTO-
Nium etc. The various current and gas management options give you complete
control over the welding process, from ignition through to the final cooling of the
weld bead.
• Pulse
Pulse current welding mode consists of a sequence of high current pulses (I,
welding pulse) followed by low current pulses (I_Cold, workpiece cooling pulse).
Pulse mode allows pieces to be assembled while limiting temperature rises and
warping. Idéal aussi en position.
Example:
The welding current (I) is set to 100 A and % (I_cold) = 50%, i.e. cold current =
50% x 100 A = 50.
F(Hz) is set to 10Hz, the period of the signal will be 1/10Hz = 100ms -> every
100ms, during this period a pulse at 100A then another at 50A will follow..
Recommendations:
Choice of frequency:
- If welding with manual filler metal, then F(Hz) is synchronised to the filler action,
- If thin without filler (< 0.8 mm), F(Hz) >> 10Hz
- Positional/vertical welding, then F(Hz) 5 < 100Hz
SPECIAL TIG WELDING PROCESSES
• Spot (Mode adjustable directly from the welding cycle)
This mode is for spot welding, which allows workpieces to be pre-assembled
prior to welding. Spot welding can be done manually using the trigger or timed
with a predefined spot welding period. Spot welding allows for better reproducibi-
lity and non-oxidised weld points.
