important information, you are strongly urged to obtain appropriate training, and to practice on
3.To begin welding, first observe all safety precautions, then attach the Ground Clamp to the workpiece in such a way as to provide good electrical conductivity between the weld area and the ground clamp. Adjust the Amperage to the correct setting, by turning the Amperage Control Knob (3) and observing the Indicator (24) through the Clear Cover (23).
4.While wearing protective clothing and holding the Electrode Clamp away from con- ducting surface, insert correct electrode (welding rod) into Electrode Clamp, at con- venient angle.
5.Turn the Switch (1) to the correct Voltage, and pause momentarily for the Trans- former (19) to fully charge.
6.Drag the electrode along the workpiece in a motion similar to striking a match. Do not “rap” the electrode on the workpiece as that may damage the electrode by dis- lodging flux and inhibit proper welding performance.
7.Once the arc is ignited, position the electrode at a 30° angle to the workpiece. While working, maintain the arc by holding the electrode away from the workpiece a dis- tance equal to the electrode’s diameter.
8.Proceed at a smooth, steady pace. Observe the weld as you proceed, tempering your motions to achieve a good weld.
Tips for Welding Success
1.Good welds depend on the action of an appropriate flux. Do not use welding rods which have a damaged or missing flux coating.
.Experienced welders often use a “weaving” technique. This is a smooth oscillating motion of the electrode during the weld process to evenly disperse the weld puddle throughout the joint. This also results in a repetitive
3.As you progress, periodically use a “Slag Hammer” and “Scratch Brush” to remove flux and slag deposits on the surface of the weld before the weld is fully cooled. This will help prevent inclusions and pitting in the weld.
4.Strive for an even weld joint that fully penetrates the workpiece, and is completely filled with the pooled welding material. Avoid leaving gaps, undercuts, cavities or excess material overflowing from the joint.
5.Minimize the Heat Affected Zone (HAZ) of your workpiece. The welding process heats the base material, and may adversely affect its tensile strength or state of
6.Do not contaminate joint by using dirty materials or tools, or using slag hammers or scratch brushes which have been previously used on different material. For ex- ample, a scratch brush previously used on steel weld may cause rust contamination if used on stainless steel weld.
