Wire Feeding; Gas Connection; Mig Welding With Gas Protection - WELDKAR WK MIG 5040 F SYNERGIC Mode D'emploi

3.5 WIRE FEEDING

Make sure that the wire diameter matches the wire
diameter groove in the drive roller of the feed motor.
Place the welding wire on the wire reel holder and feed
the wire (manually) into the feed pipe and remove the
contact tip and gas nozzle on the welding torch. By
switching on the machine and holding down the torch
switch or by using the switch (50), the welding wire can
be fed through until it comes out of the welding torch,
after which the contact tip (make sure that the diameter
of the welding wire corresponds to the diameter of the
contact tip) and the gas nozzle are mounted again.

3.6 GAS CONNECTION

- Attach the gas cylinder to the chassis, wall or any
other fixed support with a chain so that the cylinder
cannot fall and the valve can break off.
- Mount the pressure reducing valve on the gas
cylinder and tighten the nut with a wrench, making
sure that a sealing ring is fitted.
- Attach the gas hose to the pressure reducing valve
and secure with a hose clamp to prevent leakage.
- Open the gas cylinder and set the pressure to 8 - 10
liter/min.
Caution: The type of gas must correspond to the
material you want to weld.

3.7 MIG WELDING WITH GAS PROTECTION

For welding steel, a gas mixture of 85% Argon and 15%
CO² (mixed gas) is used. Other gas mixtures are also
possible, such as 80% Argon and 20% CO².
1) Connect the grounding cable to the negative DIN
terminal of the power supply (1). Connect the
ground clamp to the workpiece as close as possible
to the welding spot.
2) Connect the MIG welding torch to the MIG euro
connector (28) on the front of the wire feed unit.
Tighten the thread collar of the torch by hand,
clockwise. Important: An incorrect connection to
the MIG euro connector can lead to the formation
of sparks and can damage the machine and the
welding torch.
3) Connect the water hoses of the torch to the front
of the water cooler (30/31). Make sure the blue
(supply) and red (drainage) hoses match the color of
the connections.
4) Connect the gas hose of the connection cable to the
(tulle) connection (32) of the wire feed unit. Check
for leaks.
5) Connect the shortest part of the water hoses of the
connection cable to the back of the wire feed unit
(35/36) and the longest part of the water hoses to
the back of the water cooler (76/77). Make sure
the blue (supply) and red (drainage) hoses match
the color of the connections.
6) Connect the control cable of the connection cable to
the back of the wire feed unit (33). Use the 14-pin
female plug for this purpose. Connect the 14-pin
male plug of the control cable of the connection
cable to the rear of the power source (7).

7) Connect the power cable of the connection cable
(WKP 35-50) to the back of the wire feed unit (34).
Use the shortest part for this. Connect the longest
side of the power cable (WKP 35-50) to the back of
the power source (6).
8) Connect the connecting cable (between power
source and water cooler) to the back of the power
source (8) and the back of the water cooler (75).
9) Connect the pressure regulator to the gas cylinder
and the gas hose from the connection cable to the
pressure regulator. Check for leaks.
10) Check that the correct mains voltage corresponds
to the welding machine. Connect the machine to the
mains using the power cable.
11) Turn the machine on with the on/off switch (5).
12) The wire feed unit must be set to operate with a 500
Amp power source. To do so, hold down either the
operating button (62) or both operating buttons
(62 and 63) for ± 6 seconds. The value 350, 400
or 500 will now appear in the digital display (37).
This value can be changed by turning the control
knob (62). Set the value to 500. Press the control
knob (62) to confirm the value.
13) Set the process selection key (21) to MIG (21a).
14) If a water-cooled MIG welding torch and water
cooling unit are used, check that the water cooler
contains sufficient coolant and all connections are
connected properly. Use the selection button (51)
to select 'water cooling 'option' (52), if you want to
switch on the water cooler and use a water-cooled
torch. Select the 'air cooling 'option' (53), when
using an air-cooled welding torch. The water cooler
is then switched off.
15) Set the selection button (54) to TIG 2-stroke or
4-stroke (the corresponding LED lights up).
16) Set the welding voltage (39) manually with the
control knob (62) when using program 1. When
using a synergistic program (P-2 to P-24), you only
need to set the welding current (45).
17) When using program 1, set the wire feed rate (43)
manually with the operating button (63). When
using a synergistic program (P-2 to P-24), you only
need to set the welding current (45).
18) Set the parameters with the selector switch (57).
19) Place the MIG welding torch on the material, press
the switch on the welding torch and adjust the wire
speed so that you get an even sound (when using
program 1). If the wire speed is too high, the wire
will not have time to burn in properly and there will
be a lot of spatter and sparks. If the wire speed is
set too low, the wire will melt in droplet form and will
not give a good burn-in.
20) Do not forget to turn off the machine and close the
valve of the gas cylinder after welding.
See figure 7 for the recommended welding position .
