4. Always wear safety glass with side shield, particularly during manual or mechanical removal of slag.
High temperature slag may be projected to great distances. Pay attention to fellow workers in the
vicinity.
5. Position a fire-resistant screen around the welding area to protect persons in the vicinity from arc
rays, sparks and slag.
6. Compressed gas cylinders are potentially dangerous; consult the supplier for correct handling
procedures. Always protect cylinders from direct sunlight, flame, flames, sudden temperature changes
and low temperatures.
1.3. Fire and explosion prevention
Hot slag and sparks can cause fire outbreaks. Explosions and fires can be
prevented by following the procedure described below:
Clear away or protect inflammable objects and substances (wood, saw dust, clothing, paints,
solvents, petrol, kerosene, natural gas, acetylene, propane, etc.) with fire-proof material.
1. Always perform welding operations with caution, even when containers and tubes have been emptied
and thoroughly cleaned.
2. As a preventative measure, keep extinguishing equipment within easy reach, such as fire
extinguishers, water and sand.
3. Never weld or cut containers or pipes.
4. Never weld or cut containers or pipes (even open) containing or witch have contained substances that
could give rise to explosions or other dangerous reactions when exposed to humidity or heat sources.
1.4. Metal fume hazards
Welding fumes and gases may be hazardous if inhaled for long periods of time. Follow
the procedure below:
1.
Install a natural or forced-air ventilation system in the work area.
2.
Use a forced-air ventilation system when welding lead, beryllium, cadmium, zinc, zinc-coated or
Painted materials; wear a protective mask.
3.
If the ventilation system is inadequate, use an air respirator.
4.
Beware of gas leaks. Shield gases such as argon are dense than air, and when used in confined
spaces will replace it.
5.
In the event of welding operations in confined places (e.g. inside boilers, trenches), the welder
should be externally accompanied by another person. Always observe accident-prevention
procedures.
6.
Keep gas cylinders in a well-ventilated area.
7.
Close the main valve when gas is not in use.
8.
Do not perform welding operations near chlorinated hydrocarbon vapours produce by degreasing or
painting; the heat generated by arc rays can react to form phosgene, a highly toxic gas
9.
.Irritation of the eyes, nose and throat are symptoms of inadequate ventilation. Take immediate steps
to improve ventilation. Do not continue welding if symptoms persist
1.5. Positioning the power source
Position equipment in compliance with the following indications:
The operator must have unobstructed access to controls and equipment connections.
Do not position equipment in confined, closed places. Ventilation of the power source is
extremely important.
1. The operator must have unobstructed access to controls and equipment connections.
2. Do not position equipment in confined, closed places. Ventilation of the power source is extremely
important. Avoid dusty or dirty locations, where dust or other debris could be aspirated by the system.
3. Equipment (including wiring) must not obstruct corridors or work activities of other personnel.
4. Position the power source securely to avoid falling or overturning.
5.
Bear in mind the risk of falling of equipment situated in overhead positions.
1.6. Transporting the power source
The machine is easy to lift, transport and handle, though the following procedures must
always be observed:
1. The machine may be carried by the power source handle or a nylon strap.
2. Always disconnect the power source and accessories from mains supply before any lifting or handling
operations.
3. Do not drag, pull or lift equipment by the cables.
INSTALLATION ENVIRONMENT
The equipment is not suitable for use in washrooms, shower cubicles, pool areas or similar
environments. If you are obliged to use the unit in such areas, turn off all water supplies and check
the area has been evacuated.
The Welder was not designed for installation or use in areas where it could be subject to blows or
vibration, such as road-vehicles, railway carriages, cable-cars, aircraft, ships or boats or similar
environments (including cranes, conveyor-carriers or any other mobile equipment prone to vibration)
The Welder should never be used or stored in the rain or in snow.
Never use the Welder in an explosive, corrosive, abrasive or saline environment
2. DESCRIPTION OF THE MACHINE
VARMIG Supermig semi-automatic welding machines in this manual are intended for electric-arc welding
in a protective gas atmosphere. As protective gas the following may be used CO
2
, Argon and gas
mixtures (Ar82% - CO2 18%), depending on the welding material (alloyed or non alloyed steels, bright
metals and their alloys). The machines are particularly suitable for welding thin sheet. They are ideal for
vehicle accident repair shops and industrial use, where smaller welding intensity is required. The machine
construction meet all safety, reliability and design standards of modern welding technique.
Features:
appropriate for welding of steel (thickness 0,5
– 6,0 mm) and stainless steel (thickness 0,5 – 4 mm)
in a gas protection atmosphere Ar/CO

mixtures);
high quality of weld-seam;
high working velocity and wide field of use; simple and easy maintenance and use.
