A Look at Suspended Spot Welding Machines

A wide variety of welding processes are now available in the market, however one of the most popular is the Suspended Spot Welding. With a suspended weld process, the welder no longer needs to provide constant current to the welding coil; the welding is carried out continuously inside the confines of an air-filled vacuum chamber. The Suspended Spot Welding Controller adds to this benefit for many industries. This article will highlight what a typical controller system consists of and how it is used.

The welding controller, sometimes called the welding command unit, is placed between the welding source and the workpiece. It provides a host of benefits for industries such as the shipbuilding industry where large continuous flow of power is required. Most of the time, this is achieved with the use of dedicated electrical units connected to the appropriate sources and then controlled by a computer. When the current is required to be increased or decreased, the corresponding commands are sent from the computer which activates the appropriate relays and motor drivers. This is ideal for welding that requires high current, such as that needed for spot welding.

Another common feature used in modern weld systems is proportional valve control. This is a type of valve that automatically controls the welding fluid flow. The valve automatically opens up once a certain threshold is reached or when the welding chamber becomes too warm. However, this feature can also be controlled manually if desired. The benefit of proportional valve control is that it prevents excessive welding current from being wasted, which may be a contributing factor to overheating.

The next feature that is commonly found is a pulse width valve. A pulse width is a variable resistance value that can be set to allow varying amounts of current to pass through a welder. The higher the value, the smaller the amount of current used. In addition to providing a more even flow rate, this feature is useful when a high current is needed to be supplied to a welding chamber. However, too much current can cause overheating, which may lead to catastrophic failure.

A final common feature that is present in many modern welders is the presence of a spot-welder control. This is a type of automatic welding machine that can operate both through manual control and digitally. By providing a larger gamut of welding operations through a single machine, such as with pulse width valves, it allows operators to perform a wider range of tasks without needing to use several machines. A typical four-sided spot-welder controls the welding machine either by rotating the spindle vertically or horizontally, adjusting the voltage or pulse width, and activating a sensor or actuator.

While these are the most common welding machines used today, there are other types of welders on the market including water jet welders, wire feeders, pressure washers, and more. As technology continues to advance and new applications for welded objects increase, so does the variety of welders available. Whatever the application, there is sure to be a welding machine out there to suit your needs.
