Generator Maintenance - CHIEF Elektron MultiMig 621 Manual De Instrucciones

6.1 PLACEMENT
The weight of the welding machine is approximately 67Kg
therefore for lifting it see Fig.4.
Fig. 4
Position the unit in an area that ensures good stability, and
efficient ventilation so as to prevent metal dust (grinding)
from entering.
6.2 ASSEMBLY
Mount the rear wheels.
Mount the plug on the power cord, being especially
careful to connect the yellow/green conductor to the earth
pole. Make sure that the supply voltage corresponds to
the rated voltage of the welding machine.
Size the protective fuses based on the data listed on the
technical specifications plate.
Position the cylinder onto the support O fasten it with
belts P and connect the gas hose to the pressure reducing
valve. Mount the welding torch.
To make sure that the groove of the rollers matches the
wire diameter used, open the mobile lateral side, remove
the cover CA, release the wire press rollers by means of
the pressure adjusting knob BN, replace the rollers and
remount the cover CA. (See fig.5).

Mount the wire coil and slip the wire into the feeder and
welding torch sheath.
Block the wire press rollers with the knob BN and adjust
the pressure.
Turn on the machine.
Adjust the gas by means of key AY and then feed the wire
by means of key AW.
7 WELDING
Welding Synergic Pulsed MIG LED AP on.
Select the PRG number based on the wire diameter to be
used, the type and quality of the material, and the type of
gas, using the instructions located inside the wire feeder
compartment.
Set the functions in the submenu according to the
instructions under paragraph «Service functions».
The welding parameters are set by means of knob AI.
Synergic MIG Welding LED AQ on.
Select the PROG number based on the wire diameter
to be used, the type and quality of the material, and the
type of gas, using the instructions located inside the wire
feeder compartment.
Set the functions in the submenu according to the
instructions under paragraph «Service functions».
Adjust the wire speed and the welding voltage using the
knob AI.
Conventional MIG Welding LED AR on.
Select the PROG number based on the wire diameter
to be used, the type and quality of the material, and the
type of gas, using the instructions located inside the wire
feeder compartment.
Set the functions in the submenu according to the
instructions under paragraph «Service functions».
Adjust the wire speed and the welding voltage using the
knob AI and AN respectively.
8 MAINTENANCE
Any maintenance operation must be carried out by
qualified personnel in compliance with standard IEC
60974-4.

8.1 GENERATOR MAINTENANCE

In the case of maintenance inside the machine, make sure
that the switch L is in position "O" and that the power
cord is disconnected from the mains.
It is also necessary to periodically clean the interior of
the machine from the accumulated metal dust, using
compressed air.

8.2 PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so
that there is secure insulation between the primary and
secondary sides of the machine. Do not allow the wires
to come into contact with moving parts or those that heat
up during operation. Reassemble all clamps as they were
on the original machine, to prevent a connection from
occurring between the primary and secondary circuits
should a wire accidentally break or be disconnected.
Also mount the screws with geared washers as on the
original machine.
