Power Supply - GYS MULTIWELD 250T Manual Del Usario

POWER SUPPLY

• The MULTIWELD 250T/320T is fitted with a 16A socket type EN 60309-1 which must be connected to a three-phase 400V (50 -
60 Hz) power supply fitted with four wires and one earthed neutral.
• The MULTIWELD FV 220M is supplied with a 16 A CEE7/7 plug and may only be used in a single-phase 230 V (50 - 60 Hz) three-
wire electrical installation with a grounded neutral conductor.
This product, equipped with a «Flexible Voltage» system, can be used on an earthed electrical installation between 110V and 230V
(50 - 60Hz).
The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply and its protection
(fuse and/or circuit breaker) are compatible with the current needed by the machine. In some countries, it may be necessary to
change the plug to allow the use at maximum settings.
• The MULTIWELD FV 220M is equipped with the Protect 400 function (P400): the device switches to protection (protection light
flashes) if the supply voltage is higher than 265V. Normal operation resumes as soon as the supply voltage returns to its nominal
range.
USE WITH EXTENSION CABLES
All extension cables must have an adequate size and section, relative to the machine's voltage.
Use an extension that complies with national safety regulations.

SWITCHING ON
The ON/OFF switch is located at the back of the machine. Turn the switch on the «I» position to start the generator. This switch
must not be turned off (to «O») while welding.
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 250T/320T can weld Steel wire 0.6/1.2 mm, and Stainless Steel of 0.8/1.2 mm.
The MULTIWELD FV 220M can weld Steel wire 0.6/1.0 mm, and Stainless Steel of 0.8/1.0 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. II-A) as well as the wire feeder's roller that must be replaced 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. 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). Note that this 36V DC power supply is also com-
patible with 36 V AC preheaters. 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.
