LIQUID COOLING
FILLING
MAX
The cooling unit's tank must be filled to the MAX level recommended by the gauge on the front of the cooling unit. However, the coolant
level must never fall below the MIN level, this will bring up a warning message.
It is essential to use a specific coolant for welding machines that has low electrical conductivity as well as being anti-corrosion and
anti-freeze (ref. 052246).
The use of other coolants, in particular the standard automotive coolants, can lead to the accumulation of solid deposits in the cooling
system through electrolysis, thus degrading the cooling system and even clogging it entirely.
This recommended MAX level is essential for optimum performance of the liquid-cooled torch.
MIN Any damage to the machine caused by the use of a coolant other than the recommended variety will not be covered under the warranty..
USAGE
NEVER USE the machine's power source WITHOUT COOLING LIQUID while the pump is running.
1.
Meet the minimum coolant level. Failure to do so may result in permanent damage to the cooling system pump.
Ensure that the cooling unit is switched off before disconnecting the torch's fluid inlet and/or outlet pipes. Coolant is harmful and irritates the
2.
eyes, mucous membranes and skin. Hot liquid can cause burns.
Danger of burns from hot liquid. Never drain the cooling unit after use. The liquid inside the machine is boiling hot, wait for it to cool before
3.
draining.
In «AUTO» mode, the cooler pump starts running when welding is started. When welding stops, the pump continues to run for a further 10
4. minutes. During this time, the liquid cools the welding torch bringing it back to room temperature. Leave the power source plugged in for a
few minutes after welding to allow it to cool.
In the MIG-MAG process, the cooling system is activated by default (AUTO). To use an air-cooled MIG-MAG torch, it is necessary to switch the cooling
system off. Please refer to the interface manual to do this.
SEMI-AUTOMATIC STEEL/STAINLESS STEEL WELDING (MAG MODE)
This machine can weld steel and stainless steel wire from Ø 0.6 to 1.6 mm (II-A).
The machine is designed for use with Ø 1.0 mm steel wire (Ø 1.0/1.2 roller) as standard. The contact tip, the sheave groove and the welding torch
sheath are designed for this use. Use a torch no longer than 3 m to weld 0.6 diameter wire. The contact tip as well as the spools of the motorised
wire feed roller should be replaced by a 0.6 grooved model (ref. (réf. 061859). In this case, position it so that the marking 0.6 is visible.
To do this using steel requires a specific welding gas (Ar+CO2). The amount of CO2 may vary depending on the type of gas used. Use 2% CO2 for
stainless steel. It is necessary to connect a gas pre-heater to the gas cylinder when welding with pure CO2. For specific gas issues, please contact
your gas distributor. The gas flow rate for steel is between 8 and 15 litres per minute depending on the surroundings.
SEMI-AUTOMATIC ALUMINIUM WELDING (MIG MODE)
The equipment can weld aluminium wire from Ø 0.8 to 1.6 mm (II-B).
The use of aluminium requires a specific, pure, argon gas (Ar). Seek advice from a gas distributor for a wide selection of gases. he gas flow rate of
aluminium is between 15 and 25 l/min depending on the surrounding environment and the welder's experience.
The differences between steel and aluminium processing are as follows:
- Use specific rollers for aluminium welding.
- Put minimum pressure on the motorised reel's pressure rollers so as not to crush the thread.
- Use a capillary tube (to guide the wire between the motorised wire feeder rollers and the EURO connector) for steel/stainless steel welding only.
- Use a special aluminium torch. This aluminium torch has a Teflon coating to reduce friction. DO NOT cut away the coating at the tip of the connector!
This coating is used to guide the wire from the rollers.
- Contact tips: use a SPECIAL aluminium contact tip that matches the wire's diameter.
When using red or blue sheathing (aluminium welding), it is recommended to use the 91151 (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 1.6 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.
SEMI-AUTOMATIC «NO GAS» WIRE WELDING
This equipment can weld wire without gas protection (No Gas) from Ø 0.9 to 2.4 mm. Welding flux-cored wire with a standard nozzle can lead to
overheating and damage to the torch. Remove the original nozzle from your MIG-MAG torch.
