rugged construction will sustain continuous use.
wire feed conduit, cable, and hoses run inside of the
boom mast for protecting service lines.
wire feed spool is attached directly to the counterbalance enabling wire to feed in straight line, eliminating
many wire feeding problems.
To assemble proceed as follows:
1.
Carefully unpack both the box containing the Mast
Assembly and that containing the Counterbalance
Assembly.

COUNTERBALANCE ADJUSTMENT
The Counterbalance is equipped with an adjustment
screw for balancing adjustment. You want to bring the
torch down without too much tension from the boom
while welding; then on the other hand you want the boom
to stay in the up position when not welding. If necessary
to adjust, turn the hex socket head screw clockwise or
counterclockwise until you find the correct balance for
you.

SPOOL SPINDLE
BRAKE ADJUSTMENT
It may be necessary to adjust the brake drag on the wire
spool spindle and provide enough drag to keep the wire
spool from spinning freely after the wire feeding has
stopped.
To do this:
1.
Align arrow on red cap with arrows on spindle. You
should see the ends of two springs inside the spindle
that can be turned with a screwdriver.
2.
To loosen brake drag, turn each spring an equal
amount clockwise; To tighten drag, turn each spring
an equal amount counterclockwise.
