WIRE SPOOL DRAG ADJUSTMENT
The center bolt of the Spool Hub
Assembly is used for drag adjust-
ment.
1. If there is too much drag,
causing excessive slippage, re-
duce the drag by turning the
c e n t e r a d j u s t m e n t b o l t ,
counter-clockwise.
2. If there is not enough drag,
causing the wire spool to over-
ride and the wire to tangle,
increase the drag by turning the
center adjustment bolt,
clock-
wise.
OPERATION
The following operating instruc-
tions and detailed setup procedures
enable an operator without previous
experience to produce quality fu-
sion welds. It is recommended that
an operator without prior experi-
ence with this equipment, first
practice on scrap metal of the same
type and thickness as the material
to be welded.
OPERATING SEQUENCE
1. Make sure that the pieces of
metal to be welded are free of
grease, dirt, paint and scale.
Use a wire brush to remove paint
and scale. Paint must be com-
pletely removed to bare metal.
Grease and oil could burn and
cause a fire or safety hazard.
Failure to clean the metal prop-
erly will result in erratic and
porous welds.
2. Install the unit as directed in
the installation instructions
and make sure the work clamp is
firmly attached to a cleaned
area on the workpiece to be
welded.
3. Open the shielding gas cylinder
valve. Press the torch trigger
and listen for gas flow.
CAUTION
The welding wire will feed
when the trigger is actu-
ated. Take care that the
wire is not directed to hit
yourself or anything that
is common to the work cable
on the welder.
