MOUNTING THE GAS CYLINDER See fig.3.
4.2.
4.2.1.
Attach the black gas cylinder belt (D) to the back of the welder by passing it through the two pressed metal loops on the back panel.
Place the lower end of the cylinder (C) (Not supplied) into the metal hoop (E) and fasten the belt around the cylinder.
4.3.
CONNECTING THE GAS CYLINDER
4.3.1.
Ensure that the regulator (B) is closed (knob turned fully clockwise) and then screw it onto the cylinder (finger tight only). Once the
regulator has opened the cylinder valve, indicated by the sound of gas escaping, screw it one full turn further, which is sufficient to seal
the cylinder.
‰
WARNING! Excessive tightening of the regulator will over-compress the sealing washer and allow the gas to leak.
4.3.2.
Push the gas tube (A) into the regulator (to remove tube, press the collet in and pull the tube out).
4.3.3.
Leave the regulator closed until the welder is fully set up and you are ready to weld.
4.3.4.
When you are ready to commence welding switch the machine on and turn the regulator knob halfway for a flow of approx. 2l/min, and all
the way for a max. flow of approx. 4l/min.
4.3.5.
Always remove the flow regulator after use if the machine is to be stored for any length of time.
4.4.
FITTING A REEL OF WIRE
4.4.1.
Open the side compartment on the welder by placing your finger into the black catch and lifting both the catch and the door. The
welder is supplied with a mini spool of mild steel wire, but will accept spools of up to 5kg without modification.
4.4.2.
Referring to fig.4, rotate the pressure knob (F) anti-clockwise and remove it from the threaded spindle together with the spring (E)
and the top disc (D). Small reels of wire will run on the spindle itself. The larger 5kg wire reel will run on the larger diameter flange at
the base of the reel spindle (A). Place the wire reel (C) onto the spindle ensuring that the wire withdraws from the top of the spool in a
forwards direction towards the wire feed unit. Place the plastic top disc (D) over the end of the spindle followed by the reel spring (E).
4.4.3.
Thread the pressure knob (F) onto the end of the spindle and screw it down clockwise until the spring is partially compressed. The
reel take off pressure should be set to provide a mild braking effect to prevent overrun where loose coils of wire form on the reel. Do not
overtighten this knob as too much braking will conflict with the wire tension set on the wire drive unit.
4.4.4.
Referring to fig.5 turn the knob on the wire tension screw (B) anti-clock wise and unlatch it from the pressure roller moulding. Swing
the pressure roller moulding (A) up and away from the drive roller.
4.4.5.
Straighten 40-50mm of spool wire (do not allow wire to uncoil), and gently push wire through the plastic guide and through the
6 or 8mm feed roller groove and into the torch liner. Refer to section 7.5 on how to reverse the roller for either 6 or 8mm wire.
4.4.6.
Referring to fig.6, move the pressure roller moulding (A) back round onto the grooved drive wheel
and swing the wire tension screw (B) up to lock it in place. See 4.6 regarding wire tension.
FEEDING THE WIRE THROUGH TO THE TORCH (See fig.7)
4.5.
4.5.1.
Remove gas cup (a) and contact tip (b) from end of torch as follows:
a) Take torch in left hand with the torch tip facing to the right.
b) Grasp gas cup firmly in your right hand.
c) Turn gas cup clockwise only and pull cup out to the right.
‰
WARNING! do not turn gas cup anti-clockwise, as this will damage internal spring.
d) Unscrew the copper contact tip (right hand thread) to remove.
