Suspended Spot Welding – A Brief Guide To Choose The Right Welding Controller

Suspended Spot Welding is used for most of the joining processes between metals using flux cored welding machines. It is commonly used with various steels having hard-to-reach metal parts that are difficult to join manually. With the help of this process, joining metals becomes simple and saves precious time. With the use of metal detectors, spot welders avoid contaminating the work area and the people working there. Welding machines that are used in Suspended Spot Welding is portable and compact.

There are three kinds of welding processes: direct current (DCI), alternating current (AC) and pulse gas induction (PGI). Pulse gas induction produces more heat at faster speeds than DCI and AC. With the help of a computer, a program that defines the parameters for each type of welding process can be generated and used by the machine. The characteristics of each process are then calculated and a number of parameters for each are calculated. The most appropriate parameters are selected and then fed into the machine that performs the specific welding process.

Using a typical welding torches, we can generate a large amount of heat and it is essential for us to control the temperature of the gases and use appropriate electrode materials such as Tungsten. This is possible only if we use gas welding torches that have higher wattage output. Generally, these torches come with two electrodes that have different compositions. One is made of pure Tungsten while the other is composed of Carbon. This creates a difference in the properties of both of the electrodes.

Using a DC input, we can regulate the current into the metal that we want to join. We can also use the control valve to set the current depending upon the hardness of the metal being welded. The difference in input voltage and constant current will result in a difference in the performance and capabilities of the welding equipment. Due to its constant current source, suspended welding machines are more robust when working under high load.

Another important component that we should not forget while choosing the best welding torches for welding purposes is the operating environment. In general, we should choose a machine that has a smaller sized torch compared to other types of welding torches. If we choose a larger sized torch, it can create a lot of heat and can easily overheat the work piece. We can also experience arc flying out due to poor torch design. On the other hand, if we choose a smaller torch, it will consume less energy to operate and will also consume lesser time to complete the welding operation.

The welding controllers also play a very important role in creating a successful welding operation. The controller can allow you to accurately determine the pressure and temperature needed to weld and will also help in calculating the correct time for the flame. With a proportional valve and a good welding controller, we can expect to experience reliable power, consistent current and accurate current control. Overall, the controller will allow us to produce high quality welds with ease and consistency.
