Installation

LOCATION

Selecting the proper location can significantly increase performance, reliability and life of the arc welder.

For best results locate welder in a clean and dry environment. Dust and dirt in the welder retain moisture and increase wear of moving parts.

Place welder in an area with at least twelve inches (305 mm) of ventilation space at both the front and rear of unit. Keep all obstructions out of this ventilation space.

Store welding wire in a clean, dry location with low humidity to prevent oxidation.

Use a properly grounded receptacle for the welder and ensure welder is the only load on power supply circuit. Refer to chart on page 1 for correct circuit capacity.

Use of an extension cord is not recommended for electric arc welding machines. Voltage drop in the extension cord may significantly degrade performance of the welder.

Assembly

Welding accessories for the welder are inside wire feed compartment.

HANDLE AND BASE ASSEMBLY

1.Place handle assembly on welder, aligning two holes in plastic ends with threaded holes in welder housing (Fig. 2).

2.Insert screws through cord wraps and handle ends and fasten into cabinet.

3.Attach cylinder base to unit as shown (Fig. 3).

WORK CLAMP

1.Loosen hex bolt/nut on work clamp.

2.Insert cord (labeled ‘work clamp’ on the front panel of the welder) through clamp handle. Slide bare wire under clamp block. Tighten hex bolt/nut, making sure bare wire is clamped securely (Figure 4).

WIRE INSTALLATION

NOTE: Before installing welding wire, be sure:

a.Diameter of welding wire matches groove in drive roller on wire feed mechanism (See Fig. 5). The drive roller is marked with metric sizes:

.6mm = .024”, .8 - .9mm = .030 –

.035”

b.Wire matches contact tip in end of gun. (See Fig. 6).

A mismatch on any item could cause the wire to slip and bind.

NOTE: Always maintain control of loose end of welding wire to prevent unspooling.

1.Verify unit is off and open door panel to expose wire feed mechanism.

2.Remove the spool quick lock by pushing in and rotating 1/4 turn

counterclockwise. Then remove knob, spring and spool spacer.

3.Loosen wire feed tensioning screw on drive mechanism. This allows initial feeding of wire into gun liner by hand.

4.Install wire spool onto spindle so wire can come off spool on the end closest to the wire feed guide tube.

Do not cut the wire loose yet.

Install spool spacer, spring and quick lock knob by pushing in and turning knob 1/4 rotation clockwise.

5.Hold wire and cut the wire end from spool. Do not allow wire to unravel. Be sure end of wire is straight and free of burrs.

6.Feed wire through wire feed guide tube, over the groove in drive roll and into gun liner. Snugly tighten wire feed tensioning screw. Do not over tighten. Three to four full turns is usually correct.

7.Remove nozzle by turning counterclockwise, then unscrew contact tip from end of welding torch (See Figure 6). Plug welder into a proper power supply receptacle.

8.Turn on welder and set wire speed rate to 10. Activate gun trigger until wire feeds out past the torch end.

Turn welder off.

9.Carefully slip contact tip over wire and screw tip into torch end. Install nozzle by turning clockwise (See Figure 6). Cut wire off approximately 1/4 inch from nozzle end.

DUTY CYCLE / THERMOSTATIC PROTECTION

Welder duty cycle is the percentage of actual weld time that can occur in a ten minute interval. For example, at a 20% duty cycle, actual welding can occur for two minutes, then the welder must cool for eight minutes.

Internal components of this welder are protected from overheating with an automatic thermal switch. A yellow lamp is illuminated on the front panel (on/off switch) if the duty cycle is exceeded. Welding operations may continue when the yellow lamp is no longer illuminated.

POLARITY

To change between flux wire and MIG wire the polarity must be changed.

1.Open the wire feed door.

2.Locate red (+) and black (-) polarity connectors just above wire feed mechanism (See Figure 7).

3.For MIG welding with gas, connect torch cable from wire feed mechanism to red (+) polarity connector, then connect work cable to black (-) connector.

4.For flux-core welding, connect torch cable from wire feed mechanism to black (-) polarity connector, then connect work cable to red (+) connector.

Figure 7 - Cable connection

Shielding Gas Preparation

Improper handling ! DANGER and maintenance of

compressed gas cylinders and regulators can result in serious injury or death! Always secure gas cylinders to tank bracket kit, a wall or other fixed support to prevent cylinder from falling over. Read, understand and follow all compressed gas and equipment warnings in the safety instructions.

NOTE: Shielding gas is not required if flux-cored welding wire is used.

GAS TYPES

There are 3 types of gas generally used for gas metal arc welding; 100% argon, a mixture of 75% argon and 25% carbon dioxide (C25) or 100% carbon dioxide.

Use ONLY the type of gas

recommended for your welder. Use ONLY an inert, non-flammable type of gas. Failure to do so will result in a very hazardous situation.

NOTE: 100% carbon dioxide is not recommended due to unsatisfactory weld beads.

The 75/25 mixture is recommended for general steel welding. For aluminum welding, use 100% argon. Cylinders of either type gas may be obtained at your local welding supply outlet. Secure cylinder in place on your welding machine or other support to prevent the cylinder from falling over.

Obtaining Correct Gas Type. The gas used in any welding application for your welder must be an INERT, NONFLAMMABLE TYPE. You can get the type of gas needed from a nearby welding gas distributor (often found in the yellow pages under “Welders” or ‘Welding Equipment”).

REGULATOR

An adjustable regulator without gauges is supplied with this welder. The regulator provides a constant shielding gas pressure and flow rate during the welding process. Each regulator is designed to be used with a specific gas or mixture of gases. The argon and argon mixture use the same thread type. The 100% carbon dioxide uses a different thread type. An adapter is available at your local welding gas supplier to change between the two.

HOOKUP PROCEDURE

! WARNING

Cylinder gas is under high pressure. Point cylinder outlet away from yourself and any bystanders before opening.

1.With cylinder securely installed, stand on side of cylinder opposite cylinder outlet then remove cylinder cap and open valve slightly by turning

Welding Guidelines (Continued)

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 15.

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.

WELD ANGLE

Weld angle is the angle at which the nozzle is held during the welding process. Using the correct angle ensures

proper penetration and bead formation. As different welding positions and weld joints become necessary, nozzle angle becomes an increasingly important factor in obtaining a satisfactory weld. Weld angle involves two positions - travel angle and work angle.

Travel angle is the angle in the line of welding and may vary from 5º to 45º from the vertical, depending on welding conditions.

5º - 45º

WORK ANGLE

5º - 45º

TRAVEL ANGLE

Figure 14 - Weld Angle

Work angle is the angle from horizontal, measured at right angles to the line of welding. For most

applications, a 45º travel angle and 45º work angle is sufficient. For specific applications, consult an arc welding handbook.

WIRE SPEED

The wire speed is controlled by the knob on the front panel. The speed needs to be “tuned” to the rate at which the wire is being melted in the arc. Tuning is one of the most critical functions in wire feed welding. Tuning should be performed on a scrap piece of metal the same type and thickness as that to be welded. Begin welding with one hand “dragging” the gun nozzle across the scrap piece while adjusting the wire speed with the other hand. Too slow of speed will cause sputtering and the wire will burn up into the contact tip. Too fast a speed will also cause a sputtering sound and the wire will push into the plate before melting. A smooth buzzing sound indicates the wire speed is properly tuned. Repeat the tuning procedure each time there is a change in heat setting, wire diameter or type, or work piece material type or thickness. For Aluminum, wire speed is typically set higher (7-9 speed range).

TRAVEL SPEED

The travel speed is the rate at which the torch is moved across the weld area.

Welding Guidelines (Continued)

Factors such as diameter and type of weld wire, amperage, position, and work piece material thickness all effect the speed of travel necessary for completing a good weld (See Fig. 15). When the speed is too fast, the bead is narrow and bead ripples are pointed as shown. When the speed is too slow, the weld metal piles up and the bead is high and wide. For Aluminum, travel speed is typically faster.

SLAG REMOVAL (FLUX-CORED WIRE ONLY)

Wear ANSI approved safety

glasses (ANSI Standard Z87.1) and protective clothing when removing slag. Hot, flying debris can cause personal injury to anyone in the area.

After completing the weld, wait for the welded sections to cool. A protective coating called slag now covers the weld bead which prevents contaminants in the air from reacting with the molten metal. Once the weld cools to the point that it is no longer glowing red, the slag can be removed. Removal is done with a chipping hammer. Lightly tap the slag with the hammer and break it loose from the weld bead. The final clean-up is done with a wire brush. When making multiple weld passes, remove the slag before each pass.

WELDING POSITIONS

Four basic welding positions can be used; flat, horizontal, vertical, and overhead. Welding in the flat position is easier than any of the others because welding speed can be increased, the molten metal has less tendency to run, better penetration can be achieved, and the work is less fatiguing. Welding is performed with the wire at a 45º travel angle and 45º work angle.

Other positions require different techniques such as a weaving pass, circular pass, and jogging. A higher skill level is required to complete these welds.

Overhead welding is the least desirable position as it is the most difficult and dangerous. Heat setting and wire

selection will vary depending upon the position.

All work should be performed in the flat position if possible. For specific applications, consult an arc welding technical manual.

WELD PASSES

Sometimes more then one pass is necessary to fill the joint. The root pass is first, followed by filler passes and the cover pass. If the pieces are thick, it may be necessary to bevel the edges that are joined at a 60º angle. Remember to remove the slag before each pass for gasless process.

ALUMINUM WELDING

Any aluminum surface to be welded, must be cleaned thoroughly with a

stainless steel brush to eliminate any oxidation on the weld and grounding surface. 100% Argon shielding gas must be used when welding aluminum. If 100% Argon is not used, metal penetration is unlikely. A Teflon® wire liner, smooth-groove drive roller and aluminum contact tips are recommended when welding aluminum. Campbell Hausfeld offers these parts in Kit WT2530. Call 800-746- 5641 to order.

PUSH VS PULL TECHNIQUE

The type and thickness of the work piece dictates which way to point the gun nozzle. For thin materials (18 gauge and up) and all aluminum, the nozzle should point out in front of the weld puddle and push the puddle across the workpiece. For thicker steel, the nozzle should point into the puddle to increase weld penetration. This is called backhand or pull technique (See Figure 18).

Operating Instructions and Parts Manual

Glossary of Welding Terms

AC or Alternating Current - electric current that reverses direction periodically. Sixty cycle current travels in both directions sixty times per second.

Arc Length - the distance from the end of the electrode to the point where the arc makes contact with the work surface.

Base Metal - the material to be welded.

Butt Joint - a joint between two members aligned approximately in the same plane.

Crater - a pool, or pocket, that is formed as the arc comes in contact with the base metal.

DC or Direct Current - electric current which flows only in one direction. The polarity (+ or -) determines which direction the current is flowing.

DC Reverse Polarity - occurs when the electrode holder is connected to the positive pole of the welding machine. Reverse Polarity directs more heat into melting the electrode rather than the work piece. It is used on thinner material.

DC Straight Polarity - occurs when the electrode holder is connected to the negative pole of the welding machine. With straight polarity more heat is directed to the work piece for better penetration on thicker material.

Electrode - a coated metal wire having approximately the same composition as the material being welded.

Fillet Weld - approximately a triangle in cross-section, joining two surfaces at right angles to each other in a lap, T or corner joint.

Flux - a coating, when heated, that produces a shielding gas around the welding area. This gas protects the parent and filler metals from impurities in the air.

Flux Cored Arc Welding (FCAW) - also called Gasless, is a welding process used with a wire-feed welding machine. The weld wire is tubular with flux material contained inside for shielding.

Model WG2040, WG2044, WG2045, WG3000

Gas Metal Arc Welding (GMAW) - also called MIG, is a welding process used with a wire feed welding machine. The wire is solid and an inert gas is used for shielding.

Gas Tungsten Arc Welding (GTAW)

- also called TIG, is a welding process used with welding equipment with a high frequency generator. The arc is created between a non-consumable tungsten electrode and the work piece. Filler metal may or may not be used.

Lap Joint - a joint between two overlapping members in parallel planes.

Open Circuit Voltage (OCV) - the voltage between the electrode and the work clamp of the welding machine when no current is flowing (not welding). The OCV determines how quickly the arc is struck.

Overlap - occurs when the amperage is set too low. In this instance, the molten metal falls from the electrode without actually fusing into the base metal.

Porosity - gas pockets, or cavities, formed during weld solidification. They weaken the weld.

Penetration - the depth into the work piece that has been heat effected by the arc during the welding process. A good weld achieves 100% penetration meaning that the entire thickness of the work piece has been heated and resolidified. The heat effected area should be easily seen on the opposite side of the weld.

Shielded Metal Arc Welding (SMAW) - also called Stick, is a welding process with uses a consumable electrode to support the arc. Shielding is achieved by the melting of the flux coating on the electrode.

Slag - a layer of flux soot that protects the weld from oxides and other contaminants while the weld is solidifying (cooling). Slag should be removed after weld has cooled.

Spatter - metal particles thrown from the weld which cool and harden on the work surface. Spatter can be minimized by using a spatter resistant spray on the work piece before welding.

Tack Weld - weld made to hold parts in proper alignment until final welds are made.

Travel Angle - the angle of the electrode in the line of welding. It varies from 5º to 45º depending on welding conditions.

T Joint - made by placing the edge of one piece of metal on the surface of the other piece at approximately a 90º angle.

Undercut - a condition that results when welding amperage is too high. The excessive amperage leaves a groove in the base metal along both sides of the bead which reduces the strength of the weld.

Weld Pool or Puddle - a volume of molten metal in a weld prior to its solidification as weld metal.

Weld Bead - a narrow layer or layers of metal deposited on the base metal as the electrode melts. Weld bead width is typically twice the diameter of the electrode.

Work Angle - the angle of the electrode from horizontal, measured at right angles to the line of welding.
