MIG/MAG 140/160
x Switch the unit off for longer work breaks.
Unplug when work is completed and before relo-
cating the unit. In case of accidents separate the
welding power source at once from the power
supply.
General Machine Description
The MIG/MAG welding machine consists of a trans-
former (static characteristic curve), a series-con-
nected silicon rectifier, a welding circuit choke, and
a wire feed unit.
The welding machine is suitable for the welding of
different electrode wires (e.g. steel, see "Technical
Specifications") under a shielding gas cover (CO2,
mixed gas and argon).
The machine is fan cooled and has an overload pro-
tection.

Commissioning
Taking out of enclosed parts
All enclosed parts are inside the wire feed compart-
ment and can be taken out after the wire feed com-
partment cover is removed..
Installation Conditions
x The protective gas welding unit must be
installed in a dry environment with sufficient
room for cooling.
x If the unit is placed on an inclined surface it must
be secured against falling: place the unit on a
suitable level support surface.
x The unit is designed for use in covered areas.
Welding outside in the rain is not permitted.
Mains connection
x Check to see that mains voltage matches the
voltage shown on the machine's rating plate.
x Set welding step switch to "0" before plugging
in.
Shielding gas cylinder connection
x Place gas cylinder onto the welding machine's
cylinder rack and secure with the chain to the
cylinder holder at the rear of the unit. Take off
the cylinder cap and open cylinder valve briefly,
facing away from your body.
x Screw pressure reducer to the gas cylinder
valve. Run gas hose from pressure reducer to
gas inlet port of the unit.
x Recommended gas flow rate in draft-free
rooms: 5-10 l/min.
