DRIVE ROLLER
There are two grooves in the Drive
Roller. The small groove is for .024 (.6
mm) wire and the other is for .030 -
.035 (.8 - .9 mm) wire. Remove the
roller cover and flip the drive roll to
choose the correct groove (see Parts
Breakdown).
FLUX CORE WIRE
Due to small inconsistencies in wire
diameter, using one size larger tip is
recommended. For example:
• If wire diameter is .030, use .035 tip.
• If wire diameter is .035, use .040 tip.
This welder is setup for .035 (.9 mm)
wire and has a .040 tip. Since this
welder uses .030 and .035 Flux Core
Wire, the drive roller should be in its
factory pre-set condition.

MIG WIRE
(Continued)
Since MIG wire maintains fair wire
diameter consistency, the contact tip
used should match the wire size used.
When using .024 (.6 mm) wire, use the
small groove on the drive roller. When

Aluminum wire, use the factory set
large groove.
ALUMINUM WIRE
When using Aluminum wire, it is best
to use a larger size tip than the wire
size being used. For example:
• If wire diameter is .030, use .035 tip.
When using .030 - .035 (.8 - .9 mm) MIG
or Aluminum wire, use the factory set
large groove. Aluminum wire is very
weak and should not have the same
tension on the drive roller as Flux Core
or MIG wire should. When tensioning
Aluminum wire down to the Drive
Roller, turn the tension screw three full
turns or until the Drive Roller begins to
grip the wire and feed it through the
torch cable.

Wire
to shield the weld while molten.
When current is produced by a
transformer (welding machine) and
flows through the circuit to the weld
wire, an arc is formed between the end
of the weld wire and the work piece.
This arc melts the wire and the work
piece. The melted metal of the weld
wire flows into the molten crater and
forms a bond with the work piece as
shown (Figure 10).
Arc Welding Basics
Five basic techniques affect weld
quality. These are: wire selection, heat
setting, weld angle, wire speed, and
travel speed. An understanding of
these techniques is necessary for
effective welds.
HEAT SETTING
The correct heat involves the adjust-
ment of the welding machine to the
required setting. Heat or voltage is
regulated by a switch on the welder.
