New hardware and software enhancements include iARC digital welding controls, which are more than 10 times faster than the previous generation controls; Integrated PowerConnect Technology, which automatically adjusts input power; CheckPoint and Production Monitoring 2.2, which enables welding operational data viewing on devices that include desktop computers, laptop computers, iPhones, iPads and more. Welding waveform and firmware upgrades can be obtained via a standard Ethernet connection. The modular unit can also be used with the optional Surface Tension Transfer Module or the Cool Arc 55 water cooler module, as well as transitioned into automated applications.
