5.1 Safety information
Carefully read the operating instructions, in particular the

Section 2 Safety
information, before commissioning and before beginning work with this welding
current source.
Warning!
REHM welding equipment should be operated only by persons who are
trained and instructed in the use, maintenance and the safety regulations
concerning welding systems.
When welding always wear protective clothing and take care to avoid other
persons who may be in the vicinity being endangered by the UV radiation
emitted by the welding arc.
5.2 Working under increased electrical hazard (IEC
874, EN 60974-1, TRBS 2131 and BGR 500 KAP.
2.26)
REHM TIG welding systems meet the regulations for working under increased
electrical hazard in accordance with IEC 874, EN 60974-1, TRBS 2131 and BGR
500 KAP. 2.26)
For AC welding a safety unit is built into the electronic control. When AC welding
this ensures that the arc is always only ignited with DC voltage and the change to
AC current is only made after the welding current is flowing. The machine
automatically switches off the HF and the welding current if the arc is suddenly
torn away when welding. The machine is then in the basic condition.
It must be noted that for work under increased electrical hazard, the welding
current source must not be placed in this area. Regulations EN 60974-1, TRBS
2131 and BGR 500 KAP 2.26 must be observed.
