Maintenance (Continued)
3.Inspect the condition of the gun tip and nozzle. Remove any weld slag. Replace gun tip or nozzle if damaged.
! WARNING | Do not operate this |

with cracked or missing insulation on welding cables, wire feed gun or power cord.
EVERY 3 MONTHS:
1.Replace any unreadable safety labels on the welder.
2.Use compressed air to blow all dust and lint from ventilation openings.
3.Clean wire groove on drive roller. Remove wire from feed mechanism, remove screws from drive roller housing. Use a small wire brush to clean drive roll. Replace if worn or damaged

CHANGING WIRE SIZES
This welder is setup for .035 (.9mm) wire. If a different wire size is used, the wire feed drive roller and contact tip may need changing. There are two grooves in the drive roller. The small groove is for .024 (.6mm) wire and the other is
Supply Cable Replacement
1.Verify that welder is OFF and power cord disconnected.
2.Remove welder side panel to expose switches.
3.Disconnect the black power cord wire connected to the switch and the white cord wire from the transformer windings.
4.Disconnect the green power cord wire connected to welder base.
5.Loosen the cord strain relief screw(s) and pull cord out of strain relief and wire post.
6.Install new cord in reverse order.

Welding Guidelines
General
This welding machine can utilize the Flux Cored Arc Welding (FCAW) process or the Gas Metal Arc Welding (GMAW) process. The weld must be protected (shielded) from contaminants in the air while it is molten. The FCAW process uses a tubular wire with a flux material inside. The flux creates a shielding gas when melted. The GMAW 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 8).
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 adjustment of the welding machine to the required setting. Heat or voltage is regulated by a switch on the welder. The heat setting used depends on the size (diameter) and type of wire, position of the weld, and the thickness of the work piece. Consult specifications listed on the welder. It is suggested that the welder practice with scrap metal to adjust settings, and compare welds with Figure 10.
WIRE TYPE AND SIZE
The correct choice of wire type involves a variety of factors, such as welding position, work piece material type, thickness, and condition of surface to be welded. The American Welding Society, AWS, has set up certain requirements for each type of wire.
