Additional Features

Newly designed digital control and communication electronics improve weld performance and simplify the integration of the equipment in more advanced applications.

Easier Setup and Operation
The SubArc Digital Series Interface controls recognize the power source and wire drive connected, and automatically configure the system for proper operation. The easy-to understand interface provides the operator with the necessary controls to set process parameters and control output. The power sources feature simplified parallel and tandem setups — just plug the cable into the appropriate connectors.

Easy to Integrate
Easy to integrate by using a standard Modbus connection with different levels of integration possible, from simple remote operation to more complex automated systems.

Low-Voltage Accessory Operation and Improved Environmental Protection
The Digital Series accessories are powered with 24 VAC control voltage from the power source. All power sources, interface controls and wire drives are IP-23 rated providing a high level of protection for harsh environments.
