A welding system including a plurality of welding components (20, 21, 33, 43) communicating via a wireless system using low profile and planar antennas (40) is disclosed. The welding system comprises a welding power source (43) and one or more other welding system component(s) (20, 21, 33) communicating via Zigbee or other wireless communication networks. Communications are transmitted between the components (20, 21, 33, 43) of the welding system through antennas (40) mounted externally to the housing of the welding equipment(s) (20, 21, 33, 43).
