Electricity Supply; Device Presentation - GYS Magys 350-4 Betriebsanleitung

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
« synergic wire speed » function. They work on a 400V three-phase power supply. The MAGYS 450 WS has to be
used with the separate wire feeder WS-4L (ref. 033573) and the appropriate contact batch. The MAGYS 350 GR
generator has to be used with the WS-4R wire feeder (ref. 034723) 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 350-4) 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
have also holes to pass a strap on (not included).
① On – Off switch
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 10m
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.
REEL AND TORCH ASSEMBLY (FIG. 3)
• Position the reel on to the support
adapter (ref. 042889) on the support.
