In daily welding practice there are particular danger spots for
the user because of the power source configuration and the
MIG/MAG welding process.
Keep hands, hair, clothes and tools away from moving parts
such as:
• Toothed wheels
• Fans
• Wire coils and welding wires
• Motor shafts of any type
• Please thread the welding wire with utmost caution into
the wire feed nozzle !
• Never touch rotating toothed wheels and drive parts of
the wire feed unit.
• When the welding wire comes out of the current contact
tube it may hurt the hand, the eyes or the face. Therefore,
do not turn the MIG/MAG torch to the body when thread-
ing the wire.
• Do not release the start key during maintenance work at
the torch!
• Do not touch the workpiece before and after welding -
Danger of burning. (Warning: Be careful with aluminium
- no annealing colours!).
• Covers and side panels must only be opened or removed
during maintenance or repair works.
• Make sure that during operation all covers and side panels
are closed and duly assembled by means of toothed coni-
cal spring washers (earthing).
• Before welding is started, make sure that the negative
line (earth) is correctly connected to the power source and
workpiece (stray welding currents).
• Gas cylinders contain a gas under pressure (200 - 300 bar);
in the case of damage, large quantities of expanding gas
can suddenly be released. (Kinetic energy the gas cylin-
der becomes a missile!).
• Gas cylinders with compressed gas must be protected
against heat, mechanical shocks (impacts), open flames,
sparks and direct contact with the arc.
• The gas cylinder must always be secured against “falling
down”; we recommend to secure it on the cylinder holder
of the power source.
• Never move a gas cylinder without protective cap for the
valve!
• Please observe the national and international regulations
regarding the use of gas cylinders and accessories.
