Weld Controls
The PW Spot Welder Control range uses the latest Microprocessor technology to provide a cost effective solution to quality Spot Welding. Too often spot welding machines are let down by a poor quality control, which does not give accurate timing and on which it is difficult to set current consistently.
The PW Controls are all digital and offer exceptional accuracy with cost effectiveness. The Micro 8, available for both the Light and Heavy Duty ranges, is full 4-stage timer, with squeeze, Weld, Hold, and Off times. It offers dual programme facilities as standard along with Pulsation of the weld for zinc coated and heavier sheets.
A constant current version is also available, particularly useful on long electrode arms, where weld current can vary 20% or more between the edge of the component and the centre due to magnetic losses.
The Micro 8 monitors thermostats on the thyristors and the transformer, ensuring protection for both, should water flow fail or serious overuse occur.
For more sophisticated applications, where very close control is required, the WS2000 control is supplied. This is a state of the art unit, offering all of the facilities of the Micro 8 and in addition full monitoring, locally and remote with alarms when possible failures occur, heat stepping to compensate for tip wear, spot and batch counting, as well as comprehensive internal diagnostic facilities. Depending on the model offered, programming can be from a central computer, from a remote pendant or via an on board programming panel.
Both controls can be retro fitted to older spot welding machines, providing a cost effective upgrade to bring machines in line with modern quality requirements.
