MACHINE DESCRIPTION (FIG I)
1 : Adjustment of welding settings (wire speed and welding
voltage).
2 : Switch MIG/ MMA
3 : European standard torch connection.
4 : Connectors
5 : Polarity reversal cable
SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG 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 weld Steel wire 0.6/0.8mm, and Stainless Steel of 0.8mm.
The machine is fitted with Ø 0.8mm Steel or Stainless Steel rollers. The contact tube, the groove of the roller and the sleeve of
the torch are all compatible with 0.8mm wire. Should you wish to weld 0,6 wire, use a torch of maximum 3m long. The contact tip
must be changed (fig IV-D) as well as the wire feeder's roller that must be replaced by an optional reference (042339 / 039483)
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. Maximum gas pressure : 0.5 MPa (5 bars).
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 140 can be equipped to weld with aluminium wire Ø 0,8 or 1,0 (fig II-B).
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.
Maximum gas pressure : 0.5 MPa (5 bars).
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 respecting a maximum pressure of 5Nm. For
parameters of use, please refer to the instructions indicated on page 67. 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).
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 approxi-
mately a 3 seconds delay before resuming normal welding operations.
