WELDING PROCESSES

SPOT WELDING MODE
• Spot
This welding mode allows the pre-assembly of parts before welding. Spot welding can be done manually using the trigger or timed with a predefined
spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.
• Spot-Delay
This is a welding mode similar to Spot welding but with predefined weld and dwell times, as long as the trigger is held down. This function allows
welding very thin steel or aluminium metal sheet, limiting the risk of piercing and distortion (especially for aluminium welding).

Access to some of the welding settings depends on the selected welding process (Manual, Standard, etc.) and the selected display mode (Easy,
Expert or Advanced). Refer to the HMI manual.
GAS FLOW CONTROL
To check the gas flow rate on the manometer without unwinding the welding wire, press and hold push-button n°1 and follow the procedure on the
screen. This check should be done periodically to ensure the best possible welding. Refer to the HMI manual.
TIG (GTAW) WELDING MODE
INSTALLATION AND GUIDANCE
• DC TIG welding requires a protective gas shield (Argon).
• Connect the earth clamp to the positive (+) plug connector. Connect the optional TIG torch (ref. 046108) into the EURO connector of the power
source and the polarity reversal cable into the negative (-) socket.
• Ensure that the torch is properly fitted and that the consumables (vice grip pliers, collet bodies, diffusers and nozzles) are not worn out.
• The choice of electrode will depend on the current of the DC TIG process.
Translation of the original
instructions
Feature to help prevent the wire sticking to the bead. This is timed to coincide with the wire rising from the weld
pool.
This idling current is the next phase after the current is lowered.
The intensity (% of welding current) and the time (seconds) can be programmed.
Time between the end of a point (excluding Post-Gas) and the start of a new point (including Pre-Gas).
The pre-installed user settings (syngergies) allow for a fully-automatic set-up. Changing the thickness setting
automatically sets the appropriate wire tension and speed.
Downslope current.
The Hot Start is an overcurrent used at the start that prevents the wire from sticking to the workpiece. The
intensity (% of welding current) and the time (seconds) can be programmed.
The welding current is adjusted according to the type of wire used and the material to be welded.
Adjustment of the ignition current.
Used to adjust the distance between the end of the wire and the weld pool (tension adjustment).
When the torch is bled and the gas shield is created before ignition.
Set duration.
Duration of the gas protection after the arc is extinguished. It protects the workpiece and the electrode from
oxidation.
Lessens the welding current more or less. To be set according to the welding position.
Set duration.
Control over the cord's width.
Upslope current
Progressive yarn speed. Before priming, the wire moves slowly to create the first contact without jolting.
Amount of filler metal deposited and consequently the welding intensity and penetration.
