Gas Supply - GYS AUTOPULSE M1 Manuel D'utilisation

Operating manual
SEMI-AUTOMATIC ALUMINIUM WELDING (MIG MODE)
AUTOPULSE can weld aluminium wire from Ø 0.8 to 1.2 mm (II-B).
Aluminium use requires a specific pure argon gas (Ar). For specific gas requirements, please enquire with your gas distributor. The aluminium gas
flow rate is between 15 and 20 l/min depending on the environment and the welder's experience. Synergies in Pulse mode are optimized for a gas
flow between 12 and 15 liters / minute.
The differences between using the unit on steel or aluminum are:
- Use specific drive rolls for aluminium welding.
- Apply minimum pressure on the pressure rollers of the motor-driven reel to avoid crushing the wire.
- Use the capillary tube (designed to guide the wire between the drive rolls in the motor and the EURO connector) only for steel/stainless steel
welding (II-B).
- Use a torch designed for aluminium. This aluminium torch is fitted with a teflon torch liner in order to reduce frictions. DO NOT cut the liner at the
edge of the fitting! This liner guides the wire from the drive rolls.
- Contact tube: use a SPECIAL aluminium contact tube corresponding to the diameter of the wire.
When using red or blue sheathing (aluminium welding), it is recommended to use the 90950 (II-C) accessory. This
stainless steel sheath guide improves the centering of the sheath and facilitates the flow of the wire.
SEMI-AUTOMATIC WELDING IN CUSI AND CUAL (SOLDERING MODE)
The machine can weld CuSi and CuAl wire from Ø 0.8 to 1.2 mm.
In the same way as with steel, a capillary tube must be set up and a torch with a steel sheath must be used. When braze welding, pure argon (Ar)
should be used.

GAS SUPPLY

- Fit a suitable pressure regulator to the gas cylinder. Connect it to the welding station with the pipe supplied. Attach the two hose clamps to prevent
leaks.
- Ensure that the gas cylinder is held securely in place with a chain attached to the power source.
- Set the gas flow rate by adjusting the dial on the pressure regulator.
NB: To adjust the gas flow rate more easily, use the rollers on the motorised spool by pulling the trigger on the torch (loosen the brake wheel on the
motorised reel so that no wire is drawn in). Maximum gas pressure: 0.5 MPa (5 bar).
This procedure does not apply to welding in «No Gas» mode.
