I/ SAFETY STANDARDS AND GENERAL PRECAUTIONS
GENERALITIES
1. Before disassembling the product’s body, plug out the lead cable
2. The operators must have the appropriate qualification.
3. The operations of servicing can only be controlled by qualified technicians.
4. The operator is responsible for respect of the car manufacturers’ recommendations, concerning the protection
of electrical and electronic procedures (car computer, car radio, alarm, air bag, etc…)
5. It is necessary to make a regular preventive maintenance.
ELECTRICITY
1. Check that the unity must be connected to the earth coupler and that the connection to the earth is in
good condition.
2. Check that the workbench is connected to the earth coupler.
3. Make sure that the operator has no contact with the metal parts to the welded without any protection or
wet clothes.
4. Avoid being in contact with welding part
5. Before controlling or repairing, please disconnect the unit directly to the level of the plug.
PROTECTION OF EYES AND ODY
1 . During the welding process, the operator must be protected from the eventual flashes of the electrical arc
with protection clothes like leather gloves, welding aprons, safety shoes, welding helmets or glasses for filtering
radiations and projections. As well during operations of rubbing and hammering, the operator must protect his
eyes.
2. All the protection board must be in good condition and maintained in place.
Never look at an arc of welding without any protection of your eyes.
Protect the environment near the product against projections and reflections.
SMOKES AND GAS
Welding operations can cause the emission of toxic smokes and harmful metallic dusts. Use the device in a
sheltered place equipped with smoke aspirators.
The operator must wear an anti smoke mask.
The welding material must be degreased and cleaned in order to limit the toxic gas during the welding process.
FIRE
1. Check that the sparks don’t cause fire especially near inflammable material.
2. Check that fire extinguishers are not too far from the operator.
3. Leave the product in a place with air movers.
4. Don’t weld neither on container of combustibles and lubricants, even empty, nor on containers with
inflammable material.
5. Don’t weld in an atmosphere full with inflammable gas or fuel steam.

3
ELECTRO-MAGNETIC COMPATI ILITY
Near the spot-welding, check:
- There is neither no other power supply cable nor control lines, nor phone cables, nor radio or T reception
appliances, nor watches, nor mobile phones, nor magnetic cards, nor computers or any other electronic
appliance.
- There are in the surroundings (minimum 3 meters of each point of the product) no persons using active
medical appliances (pacemakers, acoustic prosthetics).
Make supplementary protections if other products are used in the same environment.

4-1) Mains connection
See paragraph III.
4-2) Connection to gas bottle and gas choice
Screw down the regulator on gas bottle. This one is connected to MAGYS and GENEGYS by a pipe
whose terminal end is fixated on the electronic valve behind the machine. You must use clamps to
avoid escape of gas.

Screw off the pipe of moto generator wire feeder
and screw down bank connection by integrating
the pipe in the front side hole.
Gas choice : :
STEEL MORE OR LESS ALLOYED
-Pure CO2 (not much used),
-Argon + CO2 (universal gas, often used),
-Argon + CO2 + O2 (not much used).

5
STAINLESS STEEL
-Argon + CO2 (often used),
-Argon + H + CO2 +N (not much used).
ALUMINIUM
- Pure argon (often used),
- Argon + He (not much used).
4-3) Connection to earth cable
For an application with a wire in normal polarity, you must connect the adapter earth clamp on the
negative terminal and take care to swivel from a ¼ the adapter.
The MIG PRO 41/35 can only works on normal polarity (+ on the torch ) if we use the wire feeder of the
generator.
4-4) Connection of the torch
All torches are with a euro connection, which can be adapted on GYS machines.
4-5) Setting of rollers
Choose those in function of the wire diameter used and the type of wire (See following board). MAGYS 410
machine is delivered with rollers double groove 0,8 / 1 for steel.

4-6) Setting of wire reel
Open the wire feeder compartment. Remove the swivel from the coil support. Take the coil and put it on the
support with taking care to block with base spin, then screw down again the swivel. For an application with a
5Kg coil (or d=200), put the adapter between the support and the coil. For an application in steel wire place in
position the capillary tube (for an application in aluminum see the paragraph III).

Slump the wire in the moto wire feeder entrance. Release the clamping at maximum. Close the plate of the
moto wire feeder. Press on « AD ANCED WIRE » (in foreside) and tighten little by little the clamping handle
until the motor start to drive the wire. (it enables the economy of gas)
4-7) Brake adjustment from the coil support
You must block this one in function of the weight coil used.
Too blocked: the motor is in difficulty and the WIRE risk not to drive.
Release: the important coil inertia can drive the wire rolling after end welding.
Open the gas. The machine is ready to operate.

VI / UTILISATION EN ALUMINIUM
The torch installation for aluminum is fundamental.
The essential precautions are the following:
- Don’t use the brass capillary tube in the euro adapter, but
use the Teflon envelope, which must come until the moto-
wire feeder roller.
- In ALUMINIUM, use a contact tube of a diameter
immediately superior to the section of the wire used.
- Use ALU rollers identical with wire diameter.
VII / OPTION FOR MIG PRO 41/35
The MIG PRO 41/35 is an evolutive welding machine. From origin machine, we can only use this one with the
moto wire feeder. Then, we can advanced the product with separated wire feeder with equipping it with a WF
wire feeder and a contact batch from 5 or 10 meters.
When the machine is fully equipped, the choice of the moto wire feeder will be in function of the commutator
position in foreside.

VIII / MAINTENANCE
You must clean out and replace regularly nozzle and contact batch of all projections. Use a spray of anti-pearl
aerosol.
We advice you to clean the covering situated in the torch by blowing it with compressed air.
IX / ADJUSTMENTS OF WELDING CYCLES : PREGAZ, POSTGAZ, URN ACK
The advanced electronic card allows to intervene on the welding parameters.
To go on ADJUSTMENT mode, you have to (when the machine is working) press during 3 seconds on the button
« MODE ». Then, every indicators switch off and the higher display indicate PRE and the lower display indicate
the PREGAZ value. This value can be modified by pressing on + or -. If you press again on, you will adjust the
POSTGAZ time (POS on the higher display). If you press a third time, you will adjust the late time to the fusion

(BURNBACK) or the free wire length (Bur on the higher display). To come back in normal mode, you have to
press again on MODE.
If, by mistake, the modified parameters doesn’t correspond anymore to the user wishes, you can
put back the welding parameters from the factory.
For that, you must switch off the machine. Then, you have to press on the button MODE and + and switch on
the machine by pressing a long time buttons MODE and +. After that, the values PRE, POS and Bur clear out.
Now, you can release buttons. News parameters are also enter in the machine.
