SAFETY
Arc welding can be dangerous and can cause serious and even fatal injuries.
Protect yourself and others. Ensure the following safety precautions are taken:
Handling
Unplug the unit, check if the chains of the gas bottle are fastened enough, don’t ride over the
wires and cables. In compliance with the EN60974-1 standard, don’t tilt the unit more than 15°
when you move or set up the welding unit.
Lifting
- Systematically remove the gas bottle.
Do not lift the unit with any other charge.
- Use simultaneously the four ring eyes being sure that the weight is well distributed and the angle
between the strap and the machine is at a minimum of 60°.
Do not lift the welding unit with
the handles.
- Use only the link chains or straps with the correct size and the same width. The hooks need to be
locked in compliance with the standard DIN 82101, shape A, minimum size 0.4. The weight with
equipment of the HEAVYMIG 350-4S is around 160kg, the HEAVYMIG 350 GR equipped weighs
around 210 kg and around 220kg for the HEAVYMIG 450 GR/450 WS.
Fuses (x2)
The low voltage circuit of the unit is pro-
tected by 2 fuses (T2A) located on the
circuit board of the generator.
Arc radiation:
Protect yourself with a helmet fitted with filters in compliance with EN169 or EN 379
Rain, steam, damp
Use your welding unit in a clean/dry environment (pollution factor ≤ 3), on a flat surface, and
more than one meter from the welding work-piece. Do not use in rain or snow.
Electrical shock:
This device must only be used with an earthed power supply. Do not touch the parts under high
voltage. Check that the power supply is suitable for this unit
Falls:
Do not place/carry the unit over people or objects.
Burns:
Wear protective (fire-proof) clothing (cotton, overalls or jeans).
Fire risks:
Remove all flammable products from the work area. Do not work in presence of flammable gases
Fumes:
Do not inhale welding gases and fumes. Use the device in a well ventilated environment, with
artificial extraction if welding indoors.
Additional precautions:
Avoid any welding operation undertaken in:
- rooms where there is an increased risk of electric shocks,
- Poorly ventilated rooms,
- In the presence of flammable or explosive material,
Use should always be approved by a «responsible expert», and made in presence of people trai-
ned to intervene in case of emergency.
Technical protection as described in the Technical Specification CEI/IEC 62081 must be imple-
mented. Welding in raised positions should not be undertaken, except in case of safety platforms
use.
People wearing Pacemakers are advised to see their doctor before using this device.
Do not use the welding unit to unfreeze pipes.
Handle gas bottles with care - there is increased danger if the bottle or its valve are damaged.
