DANGER
Electric shock!
Welding machines use high voltages which can result in potentially fatal electric shocks
and burns on contact. Even low voltages can cause you to get a shock and lead to
accidents.
• Do not touch any live parts in or on the machine!
• Connection cables and leads must be free of faults!
• Switching off alone is not sufficient!
• Place welding torch and stick electrode holder on an insulated surface!
• The unit should only be opened by specialist staff after the mains plug has been
unplugged!
• Only wear dry protective clothing!
• Wait for 4 minutes until the capacitors have discharged!
Electromagnetic fields!
The power source may cause electrical or electromagnetic fields to be produced which
could affect the correct functioning of electronic equipment such as IT or CNC devices,
telecommunication lines, power cables, signal lines and pacemakers.
• Observe the maintenance instructions! (see Maintenance and Testing chapter)
• Unwind welding leads completely!
• Shield devices or equipment sensitive to radiation accordingly!
• The correct functioning of pacemakers may be affected (obtain advice from a doctor if
necessary).
Validity of this document!
This document describes an accessory and is only valid in combination with the
operating instructions for the power source being used (welding machine)!
• Read the operating instructions, in particular the safety instructions for the power source
(welding machine)!
WARNING
Risk of accidents if these safety instructions are not observed!
Non-observance of these safety instructions is potentially fatal!
• Carefully read the safety information in this manual!
• Observe the accident prevention regulations in your country.
• Inform persons in the working area that they must observe the regulations!
Fire hazard!
Flames may arise as a result of the high temperatures, stray sparks, glowing-hot parts
and hot slag produced during the welding process.
Stray welding currents can also result in flames forming!
• Check for fire hazards in the working area!
• Do not carry any easily flammable objects such as matches or lighters.
• Keep appropriate fire extinguishing equipment to hand in the working area!
• Thoroughly remove any residue of flammable substances from the workpiece before
starting welding.
• Only continue work on welded workpieces once they have cooled down.
Do not allow to come into contact with flammable material!
• Connect welding leads correctly!
