Now unfold the wire feeder by releasing the pressure spring (14) and tipping it forwards.
Thread the wire through the guide spring over the groove of the feed roller into the guide
tube at the end of the feed and close the feed by pushing the upper rocker down and
swinging the pressure spring back up.
Then pretension the pressure spring a little, but not too tightly. If the wire is not
transported cleanly later, simply tighten it a little. Switch on the main switch (10) on the
back of the unit. The fan noise signals that the unit is ready for operation.
Press the torch button. This switches on the wire feed and transports the wire into the
hose package. Please check beforehand whether the contact tube at the front of the torch
corresponds to the wire diameter used. If not, replace it.
When the wire peeks out of the front of the torch, the process is complete. Please now
check whether the cable connection (8) at the front of the unit is polarised to (+)
(protective gas operation). If you use filler wire (NoGas), this cable is reversed to (-)!
Then close the side flap and connect the earth cable to the negative pole on the front.
Now connect the gas hose (item 4551) to the pressure regulator of your protective gas
cylinder and turn it on.
As shielding gas for normal steel/construction steel you have the choice between CO2 or
mixed gas 18 with 82% argon and 18% CO2. With mixed gas you will achieve the best results
with the least spatter. Don't be confused here, the various manufacturers have their own
sales names for this, such as Cargon, SAGOX18, protective gas18, etc. The content is
always the same.
Set the flow rate according to the wire thickness used. As a rule of thumb, 0.6 mm wire =
6l/min and 0.8 mm wire = 8l/min. The amount of gas required depends very much on the
welding parameters such as seam type, etc.
Choose the following synergic MAG welding modes with selection button (4):
- MAG with 0.6/0.8 mm welding wire and CO2 shielding gas
- MAG with 0.6/0.8 mm welding wire and Ar/CO2 mixed gas
- MAG with 0.8/0.9 mm flux cored wire (NoGas)
The MAG welding processes run synergically, which means that the optimum welding
parameters for mild steel are already preset. Via the voltmeter (2) you can additionally
fine-tune the welding voltage V and via the adjustment knob (3) adjust the wire speed
continuously from 1m/min to 10 m/min in relation to the material thickness used. Please
refer to the table at the end of this section! Connect the earth cable to the negative pole
(9) and connect it to the workpiece. After putting on your personal protective equipment,
you are now ready to weld!
To start welding, bring the torch close to the workpiece and press the button on the torch.
The gas flow is released and the wire feed pushes the wire out of the torch. As soon as the
wire touches the workpiece, there is the short circuit that melts the wire away and
through which the welding arc is formed. Make sure that the torch is held correctly. There
are clear tutorials on the internet for new and returning users.
