DINSE DIX WF 793.M, Operation Manual

4

 Optional

WARNING: The digital control unit of the welding power source 
is fitted with a control recognition device which allows it to identify 
which device is connected and take action accordingly.

REMOTE CONTROL ANALOG RC

This command:

• 

Completely replaces the ENCODER - A knob on the DIX WF 
793.M feeder’s front panel.

• 

Partially (depending on the welding process selected) replac-
es the ENCODER - V knob on the DIX WF 793.M feeder’s front 
panel.

AIR AND/OR WATER COOLED UP/DOWN TORCH

This command works as an alternative to:

• 

The ENCODER - A knob on the DIX WF 793.M feeder’s front 
panel. In “synergic” MIG MAG and “manual” MIG MAG welding 
processes, by pressing the two right (+) and left (-) buttons you 
can regulate the values for the synergic welding parameters.

• 

The ENCODER - V knob on the DIX WF 793.M feeder’s front 
panel. In the JOB welding process, by pressing the two right (+) 
and left (-) buttons you can scroll the welding points set previ-
ously.

PUSH-PULL TORCH

The push-pull torch makes it possible to improve the aluminium 
wire feed, using the motor on the torch itself. The parameters nor-
mally regulated using the ENCODER - A knob on the DIX WF 
793.M feeder’s front panel, when this torch is on, are now regulat-
ed using the potentiometer on the torch itself.

DOUBLE FEEDER

Two feeders can be used, connected to the same welding power 
source. Only the one activated by the corresponding torch button 
will be available. It is 

not

 possible to weld with both simultaneous-

ly. For further details on installation, configuration and use, con-
tact your authorised dealer.

  Maintenance and trouble shooting

SUPPLY WIRE FEEDER

The maintenance of this equipment is limited to the cleaning of 
the inside of the frame and periodic inspection of worn cables or 
loose connections. At regular intervals disconnect the welder from 
the mains, take off the cover and use dry compressed air to re-
move possible accumulations of dirt and dust. During this opera-
tion do not direct the jet of air onto electronic components. Check, 
that the gas circuit is completely free from impurities and that the 
connections are tight and that there are no leaks. Carefully check 
that the electric valve does not leak. Check the wire feeder rolls 
periodically and replace them when wear impairs the regular flow 
of the wire (slipping etc).

  Replacing the motor control board

Proceed as follows:

• 

Unscrew the 4 screws on the sides of the panel to loosen it.

• 

Extract the panel pulling it towards you with a gentle movement.

• 

Extract the back connectors.

• 

Unscrew the 4 nuts at the sides of the electronic control board.

• 

Unscrew the two nuts that secure the encoders.

• 

Remove the faulty card.

• 

Proceed the other way round for reassembly.

  Simple automation

This paragraph describes how to interface the welding power 
source with an automatic welding plant. The connection signs are 
marked and available on the “17-pole connector for accessory / 
optional extra connections” (Connector 

CA

 - see the “Wiring dia-

gram” and “Wiring Diagram Legend” paragraphs).

DIGITAL INPUTS

Activating a digital input signal means applying a clean closed 
contact to it.

•  TORCH BUTTON • Terminals 

C / D (COM)

When this signal is activated, the welding power source starts 
the welding process.

•  UP SIGNAL • Terminals 

D (COM) / F

When this signal is activated, the welding power source increas-
es the value set beforehand for the welding synergy parameters.

•  DOWN SIGNAL • Terminals 

D (COM) / E

When this signal is activated, the welding power source decreas-
es the value set beforehand for the welding synergy parameters.

ANALOGUE INPUTS

These inputs must be piloted by a direct voltage that can be regu-
lated between 0V and 10V.

Their input impedance exceeds 400 kΩ (to enable functionality of 

these inputs the voltage between terminals 

P(-)

 and 

R (+)

 must 

exceed 0,5V).

•  PARAMETER REGULATION - A • Terminals 

P(-) / R (+)

By regulating the voltage on this input between 1V and 10V the 
welding synergy parameters (WELDING WORKPIECE THICK-
NESS, WELDING CURRENT, WIRE SPEED) are regulated from 
the minimum to the maximum value.

•  PARAMETER REGULATION - V • Terminals 

P(-) / S (+)

By regulating the voltage on this input between 1V and 10V 
the welding parameters (ARC LENGTH, WELDING VOLTAGE, 
ELECTRONIC INDUCTANCE) are regulated from the minimum 
to the maximum value.

DIGITAL OUTPUTS

Activating digital output signals means closing a clean contact.

•  ARC ON • Terminals 

T / L

The welding power source activates this signal when it detects 
current passing through the welding circuit.
