This manual contains safety and operating instructions. Read it carefully before using the device for the first time and
keep it in a safe place for future reference.
GENERAL DESCRIPTION
Thank you for choosing this GYS product; please read this instruction manual carefully before installing and using the
product, and keep in a safe place for future reference.
The MAGYS are ventilated semi-automatic welding units (MIG or MAG). Adjustment is quick and easy with their « syner-
gic wire speed » function. They work on a 400V three-phase power supply.
In order to function MAGYS:
• 400 GR requires separate wire feeder WS-4R (ref. 034723) or W5S-4L (ref 032835) and a connection cable.
• 500 GR requires separate wire feeder WS-4R (ref. 034723) or W5S-4L (ref 032835) and a connection cable.
• 500 WS requires separate wire feeder WS-4L (ref. 033573) or W5S-4L (ref 032835) and a connection cable.
ELECTRICITY SUPPLY
The absorbed current (I1eff) is indicated on the device, for use at maximum settings. Check that the power supply and
its protection (fuse and/or circuit breaker) are compatible with the current needed during use.
The device must be placed in such way that the power socket is always accessible.
Do not use an extension cord which has a wire section smaller than 4 mm².
These units are supplied with a 32A plug type EEC7/7. They should be plugged in to a 400 V (3PH) power socket WITH
earth and protected by a circuit breaker (32A and 1 differential 30Ma.)
DEVICE PRESENTATION
Put the rubber mat (only for the Magys 400-4) and the four ring eyes (with their lock washers). The gas bottle needs to
be fastened with 2 chains in the holes at the back of the machine. Attention: Fasten correctly the bottle. You have also
holes to pass a strap on (not included).

2 - Power settings – 2 switches with 9 positions to adjust
the welding voltage output
3 - Control panel – Welding settings
4 - European standard torch connection
5 - Power cable (5m)
6 - Earth cable
7 - Gas bottle support (max 1 bottle of 10m3)
SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE) (FIG. 2-A)
The MAGYS units are equipped originally to work on 1mm steel wire (original drive rollers Ø 1/1.2 steel/stainless steel).
Make sure that drive rollers, liner and contact tube are adapted to your wire diameter.
For Steel or Stainless Steel, you will need to use specific gas - Argon + CO2 (Ar + CO2). The proportion of CO2 will vary
depending on usage. The gas flow for steel is between 15 and 25L / min depending on the environment and experience
of the welder.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE) (FIG. 2-B)
This welding unit can weld aluminium wires from 1mm.
To weld aluminium, neutral gas "pure Argon" (AR) is required. When choosing gas, ask a gas distributor for advice.
The gas flow in aluminium should be between 20 and 25 L / min depending on the environment and experience of the
welder.
Things to note when welding with Aluminium
- Set the pressure of the rollers to a minimum so as not to crush the wire
- Remove the capillary tube before connecting the aluminium torch
- When welding aluminium use a special aluminium torch with Teflon sheath to reduce friction.
Do not cut the sheath near the connector! It is used to guide the wire from the rollers.
(See diagram (16))
- Contact Tip: Use the specific Aluminium contact tip corresponding to the diameter of the wire.
- Drive rollers: Use specific drive rollers to weld with aluminium wire.
