4.2 Noise information in accordance with EN 60974-1
A workplace-related emission value cannot be stated for welding, because the value depends on the process
and on the surroundings. It depends on very widely varying parameters, such as the type of welding process
(MIG/MAG, TIG welding) the type of current used (direct current, alternating current), the power range, the
type of material being welded, the resonance of the workpiece, the workplace environment and other factors
as well.
The product outputs the maximum sound power level in idle state and during the cooling phase corresponding
to the maximum permissible working point under conventional load pursuant to EN 60974-1.
Noise information
A workplace-related emission value cannot be stated for stud welding, because the value depends on the
process and on the surroundings. It depends on very widely varying parameters, such as the properties of
the workpiece and the workplace environment.

5 Preparations at the workplace
▶ Check all components for damage and replace damaged components.
▶ Before use, make sure that the ground clamp and the stud holder are free of contaminants.
5.1 Setting up the product
Set-up conditions for charging and in operation
• Do not cover up the product. Air must be able to flow unhindered through the air vents at front and rear.
• To prevent product damage due to insufficient air supply, make sure that there is a clear space of 0.5 m
(2 ft) all round the product.
• Make sure that the fan does not induct metallic dust (e.g. from grinding work).
• The surface on which the product is set must be smooth and level, so that the product does not tip over
or fall.
5.2 Charging cordless welding machine
Fully charge the product before using it for the first time.
Over a long period of non-use, charge the product regularly every 6 months to prevent deep discharge.
