Safety instructions

Risk of accidents due to non-compliance with the safety instructions!
Non-compliance with the safety instructions can be fatal!
• Carefully read the safety instructions in this manual!
• Observe the accident prevention regulations and any regional regulations!
• Inform persons in the working area that they must comply with the regulations!
Risk of injury from electrical voltage!
Voltages can cause potentially fatal electric shocks and burns on contact. Even low vol-
tages can cause a shock and lead to accidents.
• Never touch live components such as welding current sockets or stick, tungsten or wire
electrodes!
• Always place torches and electrode holders on an insulated surface!
• Wear the full personal protective equipment (depending on the application)!
• The machine may only be opened by qualified personnel!
• The device must not be used to defrost pipes!
Hazard when interconnecting multiple power sources!
If a number of power sources are to be connected in parallel or in series, only a techni-
cal specialist may interconnect the sources as per standard IEC 60974-9:2010: Installa-
tion and use and German Accident Prevention Regulation BVG D1 (formerly VBG 15) or
country-specific regulations.
Before commencing arc welding, a test must verify that the equipment cannot exceed
the maximum permitted open circuit voltage.
• Only qualified personnel may connect the machine.
• When taking individual power sources out of operation, all mains and welding current leads
must be safely disconnected from the welding system as a whole. (Hazard due to reverse
polarity voltage!)
• Do not interconnect welding machines with pole reversing switch (PWS series) or machines
for AC welding since a minor error in operation can cause the welding voltages to be com-
bined, which is not permitted.
Risk of injury due to radiation or heat!
Arc radiation can lead to skin and eye injuries.
Contact with hot workpieces and sparks can lead to burns.
• Use hand shield or welding helmet with the appropriate safety level (depends on the appli-
cation).
• Wear dry protective clothing (e.g. hand shield, gloves, etc.) in accordance with
the applicable regulations of your country.
• Persons who are not directly involved should be protected with a welding curtain or suitable
safety screen against radiation and the risk of blinding!
