maximum 3m long. The contact tip must be changed (fig II A / p.75) as well as the wire feeder's roller that must
be replaced by an optional reference (042339) with a 0.6 diameter groove. In this case, the position in such
a way to observe 0.6. For use with Steel, the gas requirement is argon + CO2. (Ar+CO2). The proportion of
CO2 required will vary depending on the use. For Stainless Steel, use the combination of 2% CO2 For specific
gas requirements, please contact your gas distributor. The gas flow in steel is between 8 and 12 Litres/minute
depending on the environment.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE)
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/
recommendations printed on the side of the machine.
The GOLDMULTI can be equipped to weld with aluminium wire Ø 0,8 or 1,0 (fig II-B / p.75).
For use with aluminium, the gas requirement is pure argon (Ar). For the specific gas requirements please contact
your distributor. The gas flow in Aluminium is between 20 and 30 Litres/minute depending on the environment,
and the experience of the welder.
Below are the differences between welding with Steel and Aluminium :
- Specific rollers are needed for welding with Aluminium.
- Adjust the pressure of the drive rolls to prevent the wire being crushed.
- Only use a capilliary tube for welding with Steel or Stainless Steel.
- Use a special Aluminium Torch with a teflon sheath to reduce friction.
DO NOT cut the sheath close to the joint, it is used to guide the wire from the the rollers.
- Contact Tube : Use a special aluminium contact tube specific to the diameter of wire being used.
GASLESS WIRE WELDING
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/
recommendations printed on the side of the machine.
The GOLDMULTI can weld gasless wire up to 0.9mm, if the polarity is reversed (fig III / p.76) respecting a maxi-
mum pressure of 5Nm. For parameters of use, please refer to the instructions indicated on page 75. Welding
gasless wire with a standard nozzle can lead to overheating and deterioration of the torch. It is recommended to
use a "No Gas" nozzle (ref. 041868), or remove the genuine nozzle (Fig. III / p.76).

ELECTRODE WELDING

• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode
holder and earth clamp. Connect the electrode holder and earth clamp as indicated on the electrode packaging.
• Respect the basic rules of welding.
• This device has 1 feature specific to Inverter machines :
- Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start,
requires approximately a 3 seconds delay before resuming normal welding operations.
The proportion of CO2 can vary according to the type of metal being welded.
SETTINGS PANEL (FIG V/P.76)
• Green light «ON»: when the machine is switched on the light
turns on.
1
• In case of power failure, the green light goes off but the device
remains powered while the power cable is unplugged.
• Orange light :
• Over-temperature: in such a case you shall wait a few minutes,
2
the light will turn off and the machine will start again.
• Over-current on primary circuit: in such a case you shall switch
off the machine (with the main switch) and switch on.
