Suspended Spot Welding Controller

Suspended Spot Welding machines are widely used for most of the joining tasks involving different metals. There are numerous uses for these kinds of welding machines. The main difference between a stand-mounted and suspended Welding machine is mainly in the location of the torch or arc. If we consider the welded joints which are usually formed at the front, side or back of an object, then it is obvious that a stand-mounted Welding machine will provide more accurate work because it has a spot for the torch, a dedicated cooling chamber and a well-secured base.

Suspended Spot Welding

In a suspended spot welding machine, the torch is fixed in a housing or enclosure. The entire unit is then shielded by a cover or shield made of tungsten. There is a control unit or a controller situated externally and is programmed to control the setting and supply of current. It is equipped with a supply of fuel for the torch and several electrodes for the purpose of maintaining the current. The most important thing to note is that the electrode should be charged properly as they are the source of current. If the electrodes are overcharged, they tend to reduce the arc and also short out the welding process.

If there is a separate controller for the welding system, it is known as the welding controller. The welding controller normally has two or more terminals, which controls the welding current as well as the welding pressure automatically through a proportional valve. If the welding current is too strong, it will cause the weld to melt and this will lead to arc melting and also fire. This is not at all desirable and will lead to several accidents. Welding pressure automatic calibration is a system that is used to maintain the welding pressure automatically throughout the welding operation. When a small amount of current is supplied to the system, it will be amplified and sent through a proportional valve into the welding unit.

There are various types of welding torches available and among them the most important one is the tungsten inert gas welding torches. These welding torches are very popular worldwide. They are mainly used in all sorts of metals like iron, steel and aluminum and have a high tolerance against extreme heat and also a long endurance. They can produce welds that are thicker than conventional welds and the welds that are produced are more consistent.

Another important type of welding machine is the wire feed welding machine. This type of welding machine is mainly used to weld thinner metallic materials that do not require a spot welding controller. There is a control unit that is fitted inside the machine and is programmed to control the current and the amount of welding heat that is generated. Most of these welding machines generate a weld that is about 0.8 mm thick.

The third most popular is the MIG welder and it is operated electronically. It is mainly used for welding small items that require high welding currents. The welding current generated is controlled by a circuit and this makes it easy to control the welding currents when they are needed. This is another reason why the MIG welding controller is so popular. In short we can say that the welding controller helps us to control the welding currents that are generated and also help us in managing the welding operation properly.
