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.
• 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.
• 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.
• Insert the torch into the torch connector and screw its nut
(T1)
tightly.
• If your machine has water cooling unit and you will use water-cooled
torch, connect the cold water connector
(blue - T2)
of the torch to the
cold watersupply outlet on the wire feeding unit and connect the hot
water connector
(red - T3)
of the torch to the hot water return inlet on
the wire feeding unit.
