3.2 Connection to Mains
3.3 Preparation and Connection of the Torch
• Check the 3-phase with a voltmeter before connecting the machine to the mains. After detecting
that each phase is 400V (± 40V), attach the plug into the wall outlet.
• Start the machine with the on/off switch.
• Turn the machine off by turning the switch back to the “0” position after hearing the fan sound
and seeing the ammeter and voltmeter lights are on.
• Use the torch according to the capacity of your machine and the welding you will perform.
• Make sure that the diameters of the spiral and contact nozzle inside the torch match the diameter
of the welding wire you will use. Replace the spiral and contact nozzle if necessary.
• To change the spiral, remove the nozzle, contact nozzle and adapter respectively (Figure 13).
• Afterwards, remove the spiral nut on the torch connector side with a wrench and extend the torch
so that it is in flat position and remove the spiral inside the torch.
• After inserting the new spiral into the torch, install and firmly tighten the spiral nut (Figure 14).
• Cut the excess of the spiral from the torch head with a side chisel at the point where the gas
distributor (contact nozzle holder) immediately ends as shown on the right, so that there is no
gap between the spiral and the contact nozzle. File the cut point to make it blunt and burr free
(Figure 15).
When plugging the power plug into the outlet, make sure that the power switch is set to “0”.

• Connect the torch to the torch connector and tighten the nut
(T1)
firmly.
• If your machine has a water-cooling system and you are using a water-cooled torch, connect
the cool water connector of the torch
(blue - T2)
to the cold-water outlet in the wire feed unit
and the hot water connector of the torch
(red -T3)
to the hot water inlet in the wire feed unit
(Figure 16).
