Generator Maintenance - CHIEF Elektron MultiMig 522 Manual De Instrucciones

6.2 ASSEMBLY
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.
This welding machine
contemporarily mount 2 welding torches and 2 coils of
wire having a diameter of 300mm; this machine cannot
weld with the 2 torches at the same time, the torch
selection is made by means of selector switch D.
The gas cylinder must be equipped with a pressure
regulator and a gauge. If the cylinder is placed on the
cylinder shelf of the trolley, it must be fastened using
the strap provided. Only after positioning the cylinder,
connect the outgoing gas hose from the rear panel of the
machine to the pressure regulator.
2 gas hoses leave the rear panel, one is used in
combination with central adapter B and the other one
with central adapter B1. In order to select the right
combination read the plate at its side.
Adjust the gas flow to approximately 8/10 liters/minute
To make sure that the groove of the roller matches the
wire diameter used, open the mobile lateral side, remove
the cover CA, release the wire press roller by means of
the pressure adjusting knob BN, replace the roller and
remount the cover CA. (See fig.4).

Fig. 4
Mount the wire coil and slip the wire into the feeder and
welding torch sheath.
Block the wire press roller 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.
NOTE: If 0.6mm diameter wires are used the welding
torch sheath should be replaced with one of suitable
internal diameter.
If the internal diameter of the sheath is too big it does not
guarantee smooth wire feeding.

to
instructions under paragraph «Service functions».
5.2.3The welding parameters are set by means of knobAI.
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.
