Changing Wire Sizes

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.

Welding Guidelines

General

This line of welding machines can

utilize the Flux Cored Arc Welding

(Gasless) process or the Gas Metal Arc

Welding (MIG) process. The weld must

be protected (shielded) from

contaminates in the air while it is

molten. The gasless process uses a

tubular wire with a flux material inside.

The flux creates a shielding gas when

melted. The MIG process uses inert gas

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.

MIG WIRE

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

using .030 - .035 (.8 - .9 mm) MIG or

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.
