Safety Guidelines These general safety norms cover both arc welding machines and plasma cutting machines unless otherwise noted. The equipment must only be used for the purpose it was designed for. Using it in any other way could result in damage or injury and in breach of the safety rules. Only suitably trained and competent persons should use the equipment.

Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot work pieces, and hot equipment can cause fires and burns. Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode. Accidental contact of electrode to metal objects can cause arcs, explosion, overheating, or fire.

LF Declaration Consult the data plate on the equipment for the power supply requirements. Due to the elevated absorbency of the primary current from the power supply network, high power systems affect the quality of power provided by the network. Consequently, connection restrictions or maximum impedance requirements permitted by the network at the public network connection point must be applied to these systems.
For your own safety and that of your working environment, pay particular attention to the safety instructions in the manual. For more information on SifWeld products, contact an authorised SifWeld dealer, or visit the SifWeld web site at www.sifweld.com. The specifications presented in this manual are subject to change without prior notice.

Gas selection Metal inert gas welding (MIG): Uses Argon (Ar), Helium (He) or Ar-He mixtures as the shield gas, and is mainly used for welding aluminium and its alloys. Metal active gas welding (MAG): Uses Argon (Ar) mixed with a certain amount of CO2 / O2 as the shield gas, and is usually used on steels in short circuit transfer and spray transfer.
4. Troubleshooting In the event of a failure of the machine, contact an authorised SifWeld service centre. The following operation requires sufficient professional knowledge on electric aspects and comprehensive safety knowledge. Make sure the input cable of the machine is disconnected from the electricity supply and wait for 5 minutes before removing the machine covers.
NOTE! Remember that the machine may be repaired only by an electrical contractor or installer trained and authorised to perform such operations. 5.3 Regular maintenance Authorised SifWeld service centres can perform regular preventative maintenance by agreement.
