3 Starting-up
In this chapter you learn what to observe during setting-up and starting-up of the power
unit.
3.1 Requirements of Workplace
Vapors and airborne particles may occur during stud welding
operations. Especially with surface treated materials, toxic
vapors may be produced.
Ensure that a fume extraction is available and that the room is adequately
ventilated according to accident prevention regulations.
If possible, do not weld in rooms which are lower than 3 meters.
Special regulations apply for confined rooms, according to accident prevention
regulations of the official bodies (see appendix).
Weld only in adequate distance from combustible articles or liquids.
Before you start welding, remove any combustible articles or liquids in vicinity of
the workplace.
Make sure that a fire extinguisher is within reach.
Never weld in rooms exposed to risk of explosion.
Do not set-up the product in the vicinity of any apparatus or equipment which is
sensitive to welding spatters.
Do not set-up the product in the vicinity of any apparatus or equipment which is
sensitive to magnetic fields.
Set-up the power unit:
– on a stable, clean and level surface
– so that no-one is influenced or injured by welding spatters
– so that all cables and primary lines are protected from being damaged
– so that nobody will trip or fall over the cables or connection lines.
Ensure that air is able to circulate freely through the housing.
If heat is built-up inside the housing caused by bad air circulati-
on, the stud welding unit will be seriously damaged.
