Becoming proficient at how to use an electric welder may seem like a very difficult task. Fortunately it is actually a simple process if you follow these crucible tips you will be well on your way to welding like a pro. Simply learn these welding methods and make sure to always practice on steel that is not important and learning how to weld will become a simple lesson.

When Arc Welding, the short circuit stuck in the space between the electrode and the arc center erupts into such large amount of energy and heat that it melts both the fuel rod and the base metal. When the liquid metal pool loses its heat, it binds the weld.

To consistently achieve good weld joints, it is important to be sure you are using an appropriate size welder, choose the right size arc welding electrodes, clean the work piece appropriately, and utilize skill which can only be realized through training and practice.

While wearing protective clothing and holding the Electrode Clamp away from conducting surface, insert correct electrode (welding rod) into Electrode Clamp, at convenient angle.

To begin welding, most importantly obey all safety precautions, then attach the Ground Clamp to the metal to be welded in such a way as to provide good electrical conductivity between the work piece and the ground wire. Adjust the number of amps to the correct setting.

Drag the welding electrode along in a fashion similar to striking a match. Do not "tap" the electrode as that may cause damage to the electrode by dislodging flux.

As soon as the arc is established, hold the electrode at a 30 ° angle to the work. While laying your bead, keep the arc lit by holding the electrode away from the work a distance equal to the electrode's diameter. Proceed at a smooth, even speed.

Experienced welders often use a "weaving" pattern. This is a smooth oscillating movement of the electrode during the weld process to evenly disperse the weld puddle through the joint. This also results in a repetitive wave-like pattern on the surface of the weld.

As you progress, periodically use a "Slag Hammer" and "Scratch Brush" to get rid off flux and slag deposits on the bead before the metal has cooled completely. This is important to inclusions and pitting in the weld.

Practice until you can lay an even weld bead that fully penetrates, and is completely filled with the pooled welding material. Avoid leaving gaps, undercuts, cavities or excess material overflowing from the joint ..

Always be aware of the Heat Affected Zone (HAZ). The welding process heats the base material, and may seriously weakened its tensile strength or state of heat-treatment. Expert welders apply only the amount of heat needed to leave a strong weld by moving smoothly along the weld joint, using the correct setting, and applying the electrode efficiently.

Proper welds depend on the action of a correct flux. Do not use welding rods which have gotten wet.

Never contaminate the joint by using oily slag hammers or scratch brushes. It is also important to remember that scratch brush previously used on a steel weld can often lead to rust contamination if used on stainless steel weld.
