Model WF2034
Operation (Con’t)
! WARNING
If heating, welding, or cutting materials that are galvanized, zinc plated,
lead, or cadmium plated
refer to the General Safety Information Section for instructions. Extremely toxic fumes are created when these metals are heated.
4.Connect the ground clamp to the work piece or workbench (if metal). Make sure the contact is secure. Avoid surfaces with paint, varnish, corrosion, or
5.Position the Heat Selector on the front panel to the desired setting.

NOTE: These settings are general guidelines only. Heat setting may vary according to welding conditions and materials.
6.Rotate the Wire Speed Control to setting number 5 to start with, then adjust as needed after test weld.
7.Plug the input cord into a proper voltage receptacle with proper circuit capacity. (See Chart under circuit requirements on page 1).
8.Switch the welder ON/OFF switch to the ON position.
9.Verify that the wire is extended 1/4” from the contact tip. If not, squeeze the trigger to feed additional wire, release the trigger, and cut wire to proper length.
10.Position the wire feed gun near the work piece, lower the welding helmet by nodding the head, or position the hand shield, and squeeze the gun trigger. Adjust heat setting and wire speed as needed.
11.When finished welding, turn welder off and store properly.
Maintenance
Disconnect power supply and turn
machine off before inspecting or servicing any components. Keep the wire compartment cover closed at all times unless the wire needs replacement.
Before every use:
1.Check condition of weld cables and immediately repair or replace any cables with damaged insulation.
2.Check condition of power cord and immediately repair or replace any cord if damaged.
3.Inspect the condition of the gun tip and nozzle. Remove any weld slag. Replace gun tip or nozzle if damaged.
Do not operate this
! WARNING welding machine
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 the ventilation openings.
3.Clean the wire groove on the drive roll. Remove wire from the feed mechanism, remove screws from the drive roll housing. Use a small wire brush to clean the drive roll. Replace if worn or damaged.
Consumable and Wear Parts
The following parts require routine maintenance:
•Wire feed drive roller
•Gun liner - replace if worn
•Nozzle/contact tips
•Wire - This welder will accept either 4” or 8” diameter spools.

Welding Guidelines
General
This line of welding machines utilizes the Flux Cored Arc Welding (Gasless) 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.
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 7).

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. The heat setting used depends on 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 12.
