Network Ready
All WTC welding controls are network ready. The MedWeld 4000 control uses a simple RS485 MedLAN network that daisy chains up to 30 controls on one channel. The information from these controls can be brought to the plant’s Ethernet network by means of a WebVIEW Gateway. The WebVIEW Gateway is available in Single, Dual, and Quad Channel Configurations.
