Key Features & Benefits

The WB-A350 AC/DC TIG welder is built around a dual-inverter architecture which enables support of our exclusive GTAW process: AC+DC Hybrid welding.  An ideal welding mode for aluminum, it combines the cleaning action of electrode-positive welding, with the deep-penetration and focus into the base metal of electrode-negative welding…all while maintaining the shape of the tungsten electrode.

Automation Ready
Fieldbus interfaces (EtherNet/IP and PROFIBUS), supporting simple conversion from manual welding to semi-automated and fully-automated applications.  This includes support for TIG fusion as well as wire-fed applications, including those where the wire feed is synchronized with the welding pulse output.  Of course, this includes simple connection to our FD-series of welding robots through our own, high-speed CANBUS communication network.

User-Friendly Interface
Easy operation via a simple interface that revolves around a single knob to adjust weld process parameters.  Large LED displays notify both settings and weld parameters.  Interface buttons can easily be pushed even while wearing welding gloves.

Other Key Features:

• Silent Pulse Function reduces arc noise, improving the
work environment.
• Improved welding support for thin plate aluminum via
High AC Frequency.
• New waveform control allows for very stable output
• Improved instant arc start ratio.
• 100 job memory for semi-automatic and retrofit use.
