ASSEMBLY AND PREPARATION
•
Fitting a reel of wire.
•
O pen 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.
•
Referring to fig.5, 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 spool in a forwards direction and on the
same side of the compartment as the wire feed unit. Place the plastic top disc (D) over the end of the
spindle followed by the reel spring (E). 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.
•
Referring to fig.4 turn the knob on the wire lock screw (B) anti-clock wise and unlatch it from the pressure
roller moulding. Swing the pressure roller moulding (A) away from the drive roller.
•
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 6.5 on how to
reverse the roller for either 6 or 8mm wire.
••••
Refering to fig.7, move the pressure roller moulding (A) back round onto the grooved drive wheel and swing
the wire lock screw (B) up to lock it in place.
••••
Feeding the wire through to the torch. (See fig.6)
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.
•
Check welder is switched off “0” and that the earth clamp is away from the torch tip. Connect the welder to
the mains power supply and set the voltage switches to MIN/1.
