GYS GREENLINE MULTIMIG 140 Manual De Instrucciones página 14

POWER SUPPLY
This machine is fitted with a 16A socket type CEE7/7 which must be connected to a single-phase 230V (50 - 60 Hz) power supply
fitted with three wires and one earthed neutral. The absorbed current (I1eff) is indicated on the device at maximum usage. Check
that the power supply and its protection (fuse and/or circuit breaker) are compatible with the current needed for use. In some
countries, it might be necessary to change the plug to allow maximum performance. The device must be installed so that the mains
socket is accessible.
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
USING EXTENSION LEADS
All extension leads must be of a size and cross-section appropriate for the equipment's voltage.
Use an extension lead that complies with national safety regulations.
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 MULTIMIG 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 (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 MULTIMIG 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 MULTIMIG 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 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).
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.
