Secure the following safety symbols in the area of welding place:
THREAT TO LIFE to persons fitted with a pace maker
Strong electro-magnetic fields occur in the vicinity of the stud welding
unit during welding. Such fields may affect the proper function of a
pace maker. Thus persons equipped with a pace maker must not
operate the stud welding unit and must not stay in its vicinity during
welding.
During the actual welding process, you must expect red-hot welding
spatters, possibly liquid spatters, a flash, and a loud bang > 90 dB (A).
Alert any colleagues who are occupied in the vicinity of the welder.
Wear your personal protective equipment according to actual
standards (see appendix).
3.2 Connecting the Welding Gun to the Power Unit
Switch off the power unit. In this way, you avoid any risk of
electrical shock.
Plug the welding cable of the welding gun into the related socket of the power
unit.
Press-in the plug and twist firmly to the right.
