Electrical Hazards
·
The connection to power mains and servicing of
the welding machine is to be done in accord-
ance with VDE regulations or other standards
applicable in your area.
·
Ensure proper protective bonding of the supply
circuit.
·
Ensure proper protective bonding of the work-
bench.
·
Any service or maintenance work must only be
carried out by qualified personnel.
·
Replace defective or damaged parts of torch or
torch leads without delay.
·
The unit must only be connected to an earthed
outlet as a matter of principle. Only connections,
including outlets and extension cables with an
earthed plug, having an earth conductor and
installed by a qualified electrician, are permitted.
·
The fuse protection of the supply circuit must be
in accordance with local regulations. According
to these regulations fuses or miniature circuit
breakers respectively, suitable for the conductor
cross section, must be installed. Installation of a
fuse with to high an ampere rating may cause
line fire and subsequent fire damage to the
building.
·
Replace damaged torch insulation and welding
cables without delay.
·
Replacement of a damaged power cable, plug
etc. and repairs to the electrical components of
the welding machine must be left to a qualified
electrician.
·
Welding torches must not be held in an armlock,
or in such way that electricity can run through
the body.
·
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, a series-connected silicon rectifier, a weld-
ing 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
The MIG/MAG welding machine is to be set up in
dry surroundings with enough space to ensure suf-
ficient cooling. The welding machine is designed for
indoor use. It must not be use outdoors in rain.
Mains connection
·
Check to see that mains voltage matches the
voltage shown on the machine's rating plate.
·
Set welding step switch to "0" before plugging
in.
Shielding gas cylinder connection
·
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.
·
Screw pressure reducer to the gas cylinder
valve. Run gas hose from pressure reducer to
gas inlet port of the unit.
·
Recommended gas flow rate in draft-free
rooms: 5-10 l/min.
·
When using adjustable pressure reducers set
flow rate according to litre scale in the clock with
the T-screw. Turning the T-screw in increases
the gas flow rate, turning it out reduces the gas
flow rate.
·
While setting the gas flow rate, the unit must be
switched on and the torch's trigger switch held
down, so the solenoid gas valve is open. To pre-
vent wasting electrode wire swing the wire feed
unit's leaf spring to the side.
Modifications and repairs to pressure reducers are
strictly prohibited due to the hazards involved. Send
faulty pressure reducers to a service centre.
