Why Choose Suspended Spot Welding?
A common characteristic you will find with the suspended spot welding control is its ability to detect the perfect temperature of your welding environment, even under heavy metal or high-tempered conditions. The welder automatically shifts its arc to the optimum position based on the current setting you set, depending on the precise temperature of your work environment. This is very important, because the failure to do so can result in poor weld performance and catastrophic accidents. If the weld temperature is too low, the arc will not reach the steel core at or below the weld puddle. On the other hand, if it is too high, the weld puddle may collapse, or the welder may become fatigued before reaching the proper setting.
There are several different ways in which the constant current of the welding processes can impact the physical properties of metals. Most importantly, it reduces the level of carbon dust produced during welding processes. Carbon dust impairs the ability of the welder to avoid injury or reduce the probability of fire. Because of this, most modern welders require a welding control capable of switching the welding process between carbon dioxide and carbon dust to prevent such accidents from happening. Such welding controls are available for gas, liquid, and electric conductors and are usually part of a complete welding system.
An additional benefit of using an automatic welding control is its capability to perform automatic temperature calibration. There are several situations where the welding process can go far beyond the operational temperature. These situations can result in inaccurate measurements. When this happens, adjustments to the current settings and/or the electrode material used may have to be done repeatedly, which can cause an increase in stress and overtime. Using an accurate suspend welding controller allows the welder to determine the most appropriate temperature for the job, and also prevents frequent temperature checks by the controller.
The ability of the automatic welding control to automatically adjust the welding current is also an important benefit of this type of welding gun. The accuracy of the measurements can be affected greatly by factors such as the welder’s body temperature, shirt metal thickness, workpiece material, wire feed rate, and plasma cutter load. A correctly adjusted welding current can minimize these potential errors. Most welding guns come with an automatic temperature calibration feature which enables the welder to simply flip a switch to automatically regulate welding current. Most companies also have wire feed rate adjustments which can also affect the accuracy of measurements.
Some companies also use welding equipment that includes a spot welding controller with variable metal arc voltage (VAM) induction kit. This type of welding equipment provides a very smooth continuous weld process with consistent continuity and constant current. The plasma cutter can produce extremely accurate welds, but because it is operated at a higher than necessary voltage and current, it can sometimes lead to overheating of the welded area. To avoid problems such as these, many companies have installed a VAM induction kit which provides a constant current and voltage supply to the welders. The ability to monitor weld parameters and adjust electrode current to optimize the best welds for each particular job makes this type of welding equipment very popular among contractors and manufacturing companies.
Many welders are now using modern tungsten electrodes that have a very high conductivity level and increased electrode lifetime. These electrodes are made from tungsten that is highly resistant to fatigue and corrosion and can stand up to higher temperatures. Because they require little maintenance, many contractors and manufacturers prefer to use a spot welding machine that includes a tungsten electrode. By using modern welding processes and a reliable weld controller, the accuracy and efficiency of welding processes can greatly improve.
