Models WS0900, WS0950, WS1000 and WS1020 Operation (Con’t) Maintenance DUTY CYCLE / THERMOSTATIC PROTECTION Disconnect power supply and turn machine off before inspecting or servicing any components. Welder duty cycle is the percentage of actual weld time that can occur in a ten minute interval. For example, at a 10% duty cycle, actual welding can occur for one minute, then the welder must cool for nine 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. Before every use; 1. Check condition of weld cables and immediately repair or replace any cables with damaged insulation. Do not operate this welding machine with cracked or missing insulation on welding cables, electrode holder, or power cord. Every 3 months; Replace any unreadable labels on the welder. Use compressed air to blow all dust and lint from the ventilation openings. 2. Check condition of power cord and immediately repair or replace any cord if damaged. 3. Check condition of electrode holder insulating pieces and immediately replace cracked or missing insulators. Verify that all fasteners are tight and insulated. Welding Guidelines General This line of welding machines utilizes a process known as Shielded Metal-Arc Welding (SMAW). This process is used to bond metals by heating them with an electric arc created between the electrode and the work piece. Electrodes used for shielded metal arc welding have two parts. The inner core is a metal rod or wire that should be similar in composition to the base metal. The outer coating is called flux. Various types of flux exist. Each coating is used for a particular welding situation. While the metal is molten, it can be contaminated by elements in the air. This contamination could weaken the weld. The flux coating creates a protective barrier called slag that protects the molten metal from contaminants. When current (amperage) flows through the circuit to the electrode, an arc is formed between the end of the electrode and the work piece. The arc melts the electrode and the work piece. The melted metal of the electrode flows into the molten crater and forms a bond with the work piece as shown in Figure 7. electrode approximately 1/16” off the surface or it will stick (See Figure 8). Wire Slag Flux Work Piece Weld Crater Figure 7 - Weld Components NOTE: Discontinue using and discard electrodes that burn down to 1 to 2 inches from the electrode holder. STRIKING AN ARC Place the bare end of the electrode in the holder. Grip the holder lightly to reduce tiring of the hand and arm. NOTE: Always keep the jaws of the holder clean to insure good electrical contact with the electrode. Be careful not to touch the work piece or welding bench with the electrode as this causes arc flashes. The best method of striking an arc is the scratching method. Drag the electrode at an angle along the surface much like striking a match. Upon contact with the plate, lift the 5 Same as Electrode Diameter Figure 8 - Scratching Method NOTE: Should the electrode stick to the work piece, break it loose by quickly twisting or bending at the holder while pulling upward. If the electrode does not break loose, disengage the electrode by releasing it from the holder. ELECTRODE TYPE AND SIZE Two types of electrodes are recommended for this welder. The electrodes are commonly known by the AWS (American Welding Society) designation as follows: 1. E-6013 GENERAL PURPOSE • All position, smooth deposit rod with low spatter. • For all mild steel and general purpose work. Shielded Metal Arc Welder Welding Guidelines (Continued) 2. E-7014 FAST FILL WELD ANGLE • Smooth bead and fast deposition • Ideal for joints with poor fitup and general repair work Weld angle is the angle at which the electrode is held during the welding process. Using the correct angle ensures proper penetration and bead formation. Electrode angle involves two positions travel angle and work angle (See Figure 9). NOTE: E-6011 and E-6018 are not recommended for use with these welders. Recommended electrode diameter is 1/16” or 5/64”. Call (800) 746-5641 for availability. 5o - 45o Arc Welding Basics Four basic techniques affect weld quality. These are: amperage setting, weld angle, arc length, and travel speed. Proper use of these techniques is necessary for good weld quality. Travel Angle AMPERAGE SETTING The correct amperage involves the adjustment of the welding machine to the required amp setting. This is regulated by a knob on the welder. The amperage required depends on the size (diameter) of electrode used and the thickness of the work piece. Consult specifications listed on the welder. Excessive amps burn through light metals and the weld bead is flat and porous (See Figure 10). The bead appears high and irregular if the amperage is too low. NOTE: Weld bead width (W) should be approximately twice the diameter fo the electrode rod used. Work Angle Figure 9 - Weld 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. Work angle is the angle from horizontal, measured at right angles to the line of welding. NOTE: Right handed welders should weld from left to right. Left handed welders should weld from right to left. The electrode should always point into the weld puddle as shown. ARC LENGTH Arc length is the distance from the work piece to the tip of the electrode, the distance which the arc must travel. A proper arc length is essential to generate the heat needed for welding (See Figure 10). An arc that is too long produces an unstable arc, reduces penetration, increases spatter, and causes flat and wide beads. Too short an arc does not create enough heat to melt the work piece, the electrode has a tendency to stick, penetration will be poor, and uneven beads with irregular ripples result. A proper arc should be no longer then the diameter of the rod. The sound of a proper arc is a steady, crisp sizzle, similar to bacon frying. TRAVEL SPEED The travel speed is the rate at which the electrode is moved across the weld W Workpiece Speed Too Fast Normal Amps, Arc Length, Speed Amperage Too Low Speed Too Slow Amperage Too High Figure 10 - Weld Appearance For most applications, a 45º travel angle and 45º work angle is sufficient. For specific applications, consult an arc welding handbook. Arc Length Too Long Arc Length Too Short 6 Models WS0900, WS0950, WS1000 and WS1020 Welding Guidelines (Continued) area (See Figure 10). When the speed is too fast, the bead is narrow and bead ripples are pointed as shown. When the speed is to slow, the weld metal piles up and the bead is high and wide. To control travel speed, watch the width of the weld bead (not the arc) when welding. The weld bead is the orange, molten metal behind the arc. The width should be approximately twice the diameter of the welding rod. Control travel speed to obtain a consistent bead width. SLAG REMOVAL 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. 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 (See Figure 11). 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. Cover Filler Root Figure 11 - Weld Passes 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. Other positions require different techniques such as a weaving pass, circular pass, and jogging. A higher skill level is required to complete these welds. All work should be performed in the flat position if possible. For specific applications, consult an arc welding handbook.

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 then 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 - the material used to prevent or dissolve oxides and other weld contaminants. 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. contaminants while the weld is solidifying (cooling). Slag should be removed after weld has cooled. 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. 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. 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. Tack Weld - weld made to hold parts in proper alignment until final welds are made. 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 12 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.
