GYS MULTIWELD 160M Mode D'emploi page 16

SEMI-AUTOMATIC 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/ recommenda-
tions printed on the front of the machine (fig. VII).
The MULTIWELD 160M can weld Steel wire 0.6/0.8 mm, and Stainless Steel of 0.8 mm.
The products are fitted to work with 0.8 mm steel wire (roller Ø 0.8/1.0). The contact tube, the groove of the roller and the
sleeve of the torch are all compatible with 0.8 mm wire. Should you wish to weld 0.6 wire, use a torch of maximum 3 m long. The
contact tip must be changed (fig. IV-D) as well as the wire feeder's roller (fig. IV-B) 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 recommendation 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. If welding using pure CO2 protection gas, you should connect a gas
preheater on the gas bottle (Gys reference 046511 for a 230 V version). You may also use a standard 36 V preheater module that
can be connected to the 36V power supply plug located nearby the soldering wire reel behind the lateral door (fig. I-13). For other
specific gas requirements, please contact your gas distributor. The gas flow in steel is between 8 and 12 liters / 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/ recommenda-
tions printed on the front of the machine (fig. VII).
The MULTIWELD 160M can be equipped to weld with aluminium wire Ø 0.8 and 1.0 mm.
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 15 and 25 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.
- Use the capillary tube (designed to guide the wire between the wire feeder and the EURO connector) only when welding steel or
stainless steel (fig. II).
- 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/ recommenda-
tions printed on the front of the machine (fig VII).
The MULTIWELD 160M can weld gasless wire to 0.9 mm, if the polarity is reversed (fig. III) 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).
MIG / MAG SETTINGS PANEL
CONNECTION AND RECOMMENDATIONS
• Connect the earth clamp on the positive (+) or negative (-) terminal depending on the wire type (in general on the -) .
MODE SELECTION AND SETTINGS
Press the switch
1. Setting the welding voltage :
Adjust the welding voltage using the voltage setting knob
the work to be carried out. The voltage setpoint is indicated on the left side
display.
2. Setting the wire speed :
Adjust the wire speed using the central knob
to be carried out. The speed setpoint is indicated on the central side display.
2. Inductance settings :
Adjust the inductance level using the inductance setting knob
value from MIN to MAX. The lower the inductance level, the harder and more
guiding the arc. The higher the inductance and the softer the arc with little
splatter.
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/ recommenda-
tions printed on the front of the machine (fig VII).
