2.2 Subfeeder installation
Before connecting or loading the filler wire into the subfeeder, the wire feed mechanism must be set. Ensure
that the feed rolls suit the filler wire size and type. Refer to "Feed roll kit selection" on page33 for more information.
It is not recommended to use knurled feed rolls in the X8 wire feeder unit when using the X8 SuperSnake
GT02XW subfeeder. They may apply too much friction on the filler wire at the wire feeder end preventing
the best possible outcome with the X8 SuperSnake GT02XW subfeeder.
The subfeeder is delivered with standard wire line components, if not specified otherwise. Feed rolls are to
be purchased separately. Ensure you have the correct components and feed rolls available and installed.
Tools needed:
• 12 mm wrench
• 8 mm Allen key
1. Open the feed mechanism door.
2. Release the pressure arm by lifting it up from the end (A).
3. Remove the feed roll fixing pins (B) by pulling them up.

2.3 Feed roll pressure adjustment
Adjust the feed roll pressure with the adjustment roller mounted on the pressure arm. The load applied
should be sufficient to overcome a light braking force applied by hand to the filler wire as it exits the welding
gun contact tip.
For smaller diameter and soft filler wires, less feed pressure is required. Refer to the table in the end of
this chapter for further guidance.
1. Release the pressure arm by lifting it up.
2. Turn the roller adjuster on the pressure arm to adjust the roll pressure. A graduated scale next to the
adjustment roller indicates the pressure load in newtons (N). For the correct amount of pressure, refer to
the table in the end of this section.

11/35 Rev. 1901
X8 SuperSnake GT02XW
Operating manual - EN
3. Lock the adjustment by closing the pressure arm.
Excessive pressure flattens the filler wire and may damage coated or cored filler wires. Excessive pressure
also unnecessarily wears the feed rolls and increases gearbox load.
The use of knurled feed rolls in the X8 MIG Welder’s wire feeder unit with the X8 SuperSnake GT02XW subfeeder is not recommended.
When the X8 SuperSnake GT02XW subfeeder is selected in the X8 wire feeder settings, wire inch feature
will feed the wire automatically to the system when the Wire inch button on the wire feeder panel is
pressed.

2.4 Mounting wire spool
Ensure that quality filler wire is loaded to the wire feed cabinet. Check that the correct wire guide tube and
wire feed rolls are selected and fitted for the filler wire type used.
For more information on wire spool installation and replacement, refer to the X8 MIG Welder's manual.
Check that the filler wire spool is correctly mounted and locked into position. Ensure the spool is not
damaged or deformed in such a way that it can rub or chaff against the internal surface of the wire
feed unit chassis or door. This may result in increased drag, impacting on weld quality. This may also result in long term wire feed unit damage, rendering the unit unserviceable or unsafe to use.
When changing the wire spool, the pressure of the feed rolls is not necessary to be released. Simply ensure
that the groove of the feed roll matches the diameter of filler wire used. For the filler wire preparations, refer
to section "Preparing filler wire" on page14.

2.5 Preparing filler wire
Sharp edges on the filler wire tip may damage the wire liner.
Cut off any deformed section and with a fine file or abrasive cloth, remove any sharp edges from the filler wire
end, before loading into the subfeeder.
Ensure that the end of the filler wire is straight and without any bends or edges.
1. Straighten approximately 20 cm of filler wire and, in the wire feeder, guide the filler wire through the
inlet tube and middle wire guide tube to the outlet, which feeds the filler wire to the subfeeder and the
welding gun.
2. Push the filler wire manually so that the wire will reach the wire liner (about 20 cm).
3. Close the pressure arms in the wire feeder so that the filler wire is locked between the feed rolls. Ensure
that the filler wire sits in the feed roll grooves.

2.7 Loading filler wire into subfeeder
1. Straighten the subfeeder cable and avoid tight bends on the cable.
2. Ensure that the wire feed mechanism pressure arms are closed and correctly adjusted in both, the wire
feeder and the subfeeder.
3. Press the Wire inch button on the X8 wire feeder panel.
The system will automatically load the filler wire to the subfeeder until the wire hits the feed rolls or
when 30 meters of wire has been fed from the wire feeder. If you want to stop the automatic filler wire
feed, press the Wire inch button again.
Also shielding gas is automatically run into the system when subfeeder is connected and Wire inch is
used. If the welding is not started immediately, the gas may evaporate from the subfeeder system. In
this case, to ensure faultless weld quality, release gas into the system before welding by pressing the Gas
test button on the wire feeder panel.

18/35 Rev. 1901
X8 SuperSnake GT02XW
Operating manual - EN
2.8 Shielding gas setting
The shielding gas flow rate from the welding gun is set according to the application, weld joint, gas type and
gas nozzle shape and size. The flow rate should be measured at the welding gun nozzle via a rotameter
before welding. Normally the measure is between 10 – 20 liters per minute for various welding applications.
Handle shielding gas bottle with care. Assess the risks associated with handling and using compressed
gas. Always use a cylinder transport carriage and secure the cylinder safely.
If you have not welded for a while, the gas may have been evaporated from the subfeeder. In this case,
release gas into the system before welding.

2.9 Cooler preparation
The use of a subfeeder increases the cooling liquid consumption. Before welding, ensure that there is
enough cooling liquid in the cooler and that also the subfeeder system is filled with coolant. Add cooling liquid, as necessary, and circulate the coolant throughout the system.
Pump the coolant through the system by pressing the coolant circulation button in the front panel of the
power source.
When you press and hold the coolant circulation button, the pump starts to circulate the coolant automatically.
Press the coolant circulation button again to interrupt the fill-up, for example, if any coupling is loose.
If the line does not fill up during 1 minute after the button has been released, the automatic filling stops and
the indicator LED blinks green and red in turns. The indicator panel also includes indicator LEDs which are yellow if the coolant level is too low or the coolant temperature is too high. When there are no problems with the
circulation, the indicator LED is green.
For more instructions on operating the cooler, refer to the X8 MIG Welder manual.
