1. 3.2 Risk of internal injuries
Gases and fumes
- Gases and fumes produced during the welding process can be dangerous and hazardous to your health. Arc welding works must be carried out in
suitable ventilated areas.
- Ventilation must be adequate to remove gases and fumes during operation. All fumes produced during welding have to be efficiently removed
during its production, and as close as possible from the place they are produced.
- Vapours of chlorinated solvents can form toxic gas phosgene when exposed to ultraviolet radiation from an electric arc.
Safety in the use of gases (welding with TIG or MIG inert gases)
Compressed gas cylinders
Compressed gas cylinders are potentially dangerous. Refer to suppliers for proper handling procedures:
- No impact: secure the cylinders and keep them away from impacts.
- No excess heat (over 50°C)
Pressure relief valve
- Check that the pressure relief screw is slackened off before connecting to the cylinder.
- Check that the union is tight before opening the valve of the cylinder. Open it slowly a fraction of a turn.
- If there is a leak, NEVER tighten a union under pressure, but first close the valve on the cylinder.
- Always check that hoses are in good condition.

2. DESCRIPTION

This machine makes part of a new inverter welding generation, which uses the electronic IGBT technology, which allows:
- A considerable reduction of weight and dimensions
- Dynamic control and current welding regulation
- Internal protection of electronic components
- Great power in reduced dimensions low energy consumption.
Tig HF indicator – Arc ignition with high frequency
1
avoiding the contact with welding piece to eliminate
tungsten inclusions on welding piece
Tig Contact indicator – Arc ignition without high frequency
2
to avoid electromagnetic interferences over sensitivity
electronic devices near welding zone
3
MMA (coated electrode) indicator
15
