Safety specifications for MIG/MAG welding machines
3.3.6. Noise
• Noise may cause permanent damage to your hearing. During welding the
admissible noise level might be exceeded under unfavourable conditions.
• Please make sure that the admissible maximum values are not exceeded
(Security Administrator).
• If the maximum values are exceeded, a suitable ear protection (earplugs
or earmuffs) has to be used.
3.4 Electrical danger due to mains current and welding current
3.4.1. General information
An electric shock can prove fatal. Basically, every electric shock is extremely
dangerous .
• Do not touch live parts within or outside the power source!
• During MIG/MAG welding, the welding wire, the wire coil, the drive rollers
as well as all metal parts which touch the welding wire, are live.
• All cables must be tight, undamaged, insulated and sufficiently dimen-
sioned. The negative cable (earth cable) and the positive cable are locked
by turning to the right. Loose plugs affect the arc and thus the welding
behaviour of the power source to a
considerable extent.
• Switch the welding machine off when not in use to prevent any electrical
risk.
• Avoid contact with metal parts, wear dry, insulating clothing and safety
shoes.
• Power sources may only be used when all covers are available and correctly
installed.
3.4.2. Mains connection
The power supply must be installed by qualified personnel only!
Please ensure that the mains voltage to be used is identical to the operating
voltage indicated on the machine type plate.
According to the connection regulations the machine has to be fused and
connected by means of a mains cable. You will find the connection rules
inside the power source after removal of the cover or side panel. The cross
section of the connection cable must be adequate.
The machine must be connected to a three-phase four-wire system with
earth conductor and operated.
