Welding Unit ( Mig / Mag ); Background Information; Maintenance; Advice - GYS MONOMIG 160-1 Notice D'utilisation

WATCH OUT : let the teflon sheathing stick out of the European joint. The sheathing must stick out of the
capillar length that it replaces and that must have been previously removed at the level of the European joint.
Welding on aluminium needs a specific gas : pure argon. To choose the right gas, contact your gas distributor.
When welding on aluminium, the gas flow-rate is between 20 and 30L/min according to the environment and the
welder experience.
SETTING OF A SEMI-AUTOMATIC WELDING UNIT (MIG/MAG)
• The setting of a semi-automatic welding unit is made of successive trials.
• Set the power according to the thickness to be welded (4 positions corresponding to the 4 red switches on the
front panel of the device).
• Place the wire speed potentiometer on position 1.
• Gradually raise the wire speed until the welding arc crackling is stable (too slow = the arc is discontinuous ; too
fast = the wire pushes the torch back).
• If the welding power is not convenient, put the wire speed potentiometer back to position 1. Change the
position of the red switches (hole in the metal sheet = lower position ; not enough penetration = upper
position).
• Reset the wire speed to obtain a stable arc crackling.

BACKGROUND INFORMATION

• Apply the usual welding rules.
• Leave the machine connected to the supply after welding in order to let it cool down.
• Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min according to
external temperature.
•
The machine described have an output characteristic of 'constant current' type. The duty cycle are indicated in
the table below according to EN60974-1 Norm.
Note: the running hot tests have been carried out at atmosphere temperature and duty cycle has
been determined at 40°C by simulation.

MAINTENANCE

• Refer all servicing to qualified personnel.
• Disconnect the generator and wait until the ventilator stopped before working on the unit. Inside the device,
voltages and current are dangerous.
• Regularly remove the steel cover and blow off the dust with compressed air. Let check the electrical
connections (with an insulated tool) and the insulations by qualified personnel.
• Regularly control the state of the cord. If this supply cable is damaged, it must be replaced by the
manufacturer, its after sales service or a similarly qualified technician to avoid any danger.

ADVICE

•
Leave the inlets free to allow in/out air circulation.
•
Regularly change the torch contact tube and nozzle.
•
Blow in the torch sheathing to remove steel and aluminium dust.
•
Avoid welding in air current.

SECURITY

The arc welding can be dangerous and leads serious injury, may fatal. Protect yourself and
protect the others.
Respect the following warnings:

Protect yourself thanks to a welding helmet in compliance with EN175 equiped
with filters in compliance with EN 169 or EN 379. Inform and protect by the
same means any people in the welding environment.
The working environment must be clean (degree of pollution ≤ 3) and protected
against rain. Put the appliance on an even place and at least at one meter from
the parts to be welded. Do not use them under rain or snow.
This appliance may only be use with a 230V monophase supply and must be
earthed.
Do not underestimate the weight of the apparatus. Do not carry it over people or
things. Do not drop it. Do not set it brutally
