Benefits of Suspended Spot Welding Controller
Suspended Spot Welding, also known as welder spot welding is actually the same as two-part spot welding except for the fact that the welding equipment used does not have an arm holding the welding rod in place while it welds. This makes this type of Welding very convenient and fast. Instead of waiting for the arm of the welder to cool, the arc is continuously generated and the welder is working very quickly.
Suspended Spot Welding is also the only Welding procedure that makes use of two-part welding equipment. The primary difference between a suspended and stand alone Welding machine is in where the torch or rod comes from. With the former the welder stands directly over the torch with the flexible part of the spot lying underneath the tester. With the latter, the flexible part of the spot is placed over the flexible arm of the welding torch and the weld is made with the welder in place next to it holding the rod in place with tester in between.
The primary advantage of the second style of Welding is that it is extremely accurate and is capable of producing thicker metals than other types of welding processes. Because it uses two metal parts, it is also the only way to weld two pieces of metal together that are not joined. In some cases, the spot welding machine may also be used to weld metal parts that are adjacent to each other. This is possible because of the fact that the spot welder is connected to both pieces with a flexible metal arm. In some cases this two-arm configuration results in a much sturdier and accurate weld that requires less manual control.
The second important benefit is that the welding machines are much easier to use in comparison to a proportional valve and there is also a very easy proportional valve control. In the proportional valve, the weld is created by adjusting the setting of the welder’s weld parameters using a control device such as a welding pressure automatic calibration unit (WPA). It is very difficult to manually adjust the weld parameters when you are working with a proportional valve because the weld will either stick or fall. In the case of the SBS, the weld parameters can be automatically adjusted or controlled depending on the type of welding process being performed.
The third benefit is that using a WPA based control system allows for the use of more than one welder at one time without any hang-ups due to low pulse width. When the welder is operating in a high-load situation, there is an increased risk of hitting an obstruction and that is why both the welder and the welders in the line must remain at the same relative F-min and pulse width while the welder is running. But when you use a WPA-based welder and then try to increase the load condition of the welding process, there will be no need to change the control settings of either the welders themselves because there will be no change in the pulse width. Also, when the welders are operating at a lower F-min, there is increased risk for hitting an obstruction and there will be increased wear on the welds.
With all these advantages, the duty cycle of the welding equipment plays a key role especially when you want to reduce the welding current when performing a delicate weld. There are certain types of welding equipment that are automatically triggered with the welding current and there are some that needs manual activation. If the welding equipment has an automatic controller, it is much easier to manually activate the weld while you are working. If your welding current is very high and you need to reduce the current when welding thin materials, then you should consider using a WPA-based welding controller with proportional valve controls.
