Exel SG1 Pressure Controller
SG1 Pressure Controller
Internal Weld Pressure Controller
Exel's new SG1 Pressure Controller is the first automatic pressure controller for orbital tube welding of 1/8" to 6" diameter tube or pipe. Prior to the SG1, pressure calibration and control was accomplished manually. This manual interaction often occurs during the welding process. This presents many opportunites for errors to be made which often results in the failure of a weld, in many cases destroying very expensive components. By tasking the orbital welder with the job of controlling pressure during the weld they are not available to monitor the welding process or even improve efficiency by preparing the next weld joint.
The SG1 Pressure operates on a closed loop controlled, high speed iris valve. This valve is tied to the on board microprocessor which constantly monitors the internal pressure of the weld using an extremely sensitive pressure transducer.
The SG1 Pressure Controller has several modes of operation. These modes allow simple pressure control or calibration at the weld site. The SG1 Pressure Controller is a stand alone unit that can be used with any manufacturer's welding equipment.
Because the SG1 Pressure Controller constantly monitors pressure, poorly fixture mounted or aligned weld joints can be identified.
