Automatic Welding Equipment Basics
Automatic Spot Welding machines are becoming a more popular choice in welding shops for several different reasons. The first is that the welders themselves are quieter and require less mechanical upkeep. In addition, these welders can perform a variety of different jobs including straightness, cross-matching, tapping, flaring and butt welding, with the added ability to use tip dressers. These tip dressers feature multiple metal tips that allow for the welding of thinner metals like aluminum, copper, brass and stainless steel as well as stainless steel with thicker gauges of iron, steel or titanium.
The second reason an automatic spot welding equipment is preferred over other types of welding machines is because it is capable of completing tasks quicker than conventional welders. Specifically, this type of machine can weld one piece of metal in less than one minute. This is accomplished by the use of a plasma cutter. Instead of heating the weld puddle with a conventional torch, the plasma cutter breaks the weld into smaller pieces. The smaller pieces of metal are then fed into the correct position via electrodes.
Due to the tip removal feature, these welders can also be used to weld thinner materials without the use of tip pins. This makes these welders especially useful in cutting down time spent on small welds. Automatic spot welders that utilize plasma cutters often feature two types of electrodes, either being metallic or ceramic. Ceramic electrodes often require two people to operate while metallic electrodes can be operated by only one person.
Some welders may also incorporate some sort of accessory into their construction. This accessory is known as the fusion torch. This accessory is used to increase the welding efficiency of the welder. It allows the user to control the heat of the torch and, in turn, increases the quality of a weld that is produced. While it is commonly found in automatic welders, the practice has also been used in automatic spot welders for decades.
Finally, the welder must have some means of starting and stopping the welding process. One way that this is accomplished is through the use of a lithium battery. A lithium battery is the most commonly used battery in an automatic welding process. The lithium battery ensures that there is a continuous energy flow during the welding process. The energy that the welding puddle gathers is directly related to the amount of lithium batteries that the welder uses.
Automatic welders that are capable of stopping during the welding process include Tip Dusters and Tip Dressers. The tip dresser is designed to prevent dust from accumulating on the weld puddle. This is especially important when welding titanium. Another reason for tip dressers is because they prevent overheating of the welding arc. Finally, to ensure that the whole operation is efficient, it is recommended that automatic welding operations are started by the use of a spark plug.
