Wire Feeder Unit - WELDKAR WK MIG 5040 F SYNERGIC Mode D'emploi

18) Welding current (only available with MMA, MMA
VRD, and TIG): 10-500 Ampere. This parameter
can be selected by turning the control knob (12).
The lighting of this LED indicates that the display
shows the welding current. This value can be
changed by turning the control knob (12).
19) Arc Force (only available from MMA and MMA
VRD): 0-10. This parameter can be selected by
turning the control knob (12). The lighting of this
LED indicates that the display shows the Arc Force
setting. This value can be changed by turning
the control knob (12). Increasing the Arc Force
voltage prevents sticking of the electrode during
the welding process.
20) Down Slope (only available with TIG):
0.0 – 10.0 seconds
To set the time in which the current reaches the
minimum value and switches off the arc. This
parameter can be selected by turning the control
knob (12). The lighting up of this LED indicates
that the display shows the Arc Force setting. This
value can be changed by turning the control knob
(12).
21) Process Selection Button. This control knob is
to select the desired welding mode. There are four
modes available: MIG, MMA (electrode), MMA
VRD and TIG welding.
21a) LED light indicating that the MIG mode is switched
on. The MIG parameters can be selected and set
on the control panel of the wire feed unit.
21b) LED light indicating that the MMA (electrode)
mode is switched on.
21c) LED light indicating that the MMA VRD mode is
switched on. VRD stands for Voltage Reduction
Device. This is a safety system that reduces the
open voltage across the positive and negative
poles to a safe level, consequently, reducing the
risk of electric shock.
21d) LED light indicating that the LIFT TIG mode is
switched on. The flame arc occurs by carefully
lying the tungsten electrode onto the workpiece,
pressing the torch switch and then lifting the
welding torch. The welding current only starts
when the electrode is lifted from the workpiece.
22) Selection button for 2-stroke or 4-stroke
mode (only to be used with LIFT TIG). TIG
2-stroke: With this setting, the torch switch needs
to be held down. TIG 4-stroke: This setting eases
the work when welding longer pieces. In this mode,
you can press the torch switch once and release it.
The welding current remains switched on and the
welding machine continues to supply protective
gas. If you press the torch switch again and
release it, the supply of gas and the weld ends.
23) LED light indicating that the 2-stroke mode is
switched on.
24) LED light indicating that the 4-stroke mode is
switched on.

25) Selection Button for Air Cooling or Water
Cooling (can only be used with LIFT TIG).
Use this selection button to select 'water cooling
'option' (27), if you want to switch on the water
cooler and use a water-cooled torch. Select the
'air cooling 'option' (26), when using an air-
cooled welding torch. The water cooler is then
switched off. Note: The welding machine comes
standard with a water cooler and, optionally, with
a water-cooled MIG welding torch or a TIG welding
torch. Working with a water-cooled welding torch,
without water cooling, can result in damage to the
welding torch. Damage to welding torches or parts
due to insufficient water cooling is not covered by
the warranty on the machine.
26) LED light indicating that the air-cooled mode is
switched on.
27) LED light indicating that the water-cooled mode is
switched on.
