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 titanium
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
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.
