    摘要: A welding system and method provide for generating a controlled waveform for welding power output, the waveform comprising a plurality of successive peak phases (84) designed to avoid or reduce micro-arcing when used with metal-cored or flux-cored electrode wires. Ratios of the background current and voltage levels are elevated as compared to conventional techniques, with the levels in most cases exceeding 50% of the peak currents and voltages. Transitions between background and peak levels of current and voltage are also smoothed (88), and the duration of the peak phase as compared to the duration of each pulse cycle is elongated to further reduce micro-arcing.

    摘要: A welding system includes a power source configured to generate power and deliver the power to a welding torch. The power is provided in accordance with an electrode negative pulse welding regime that includes a cyclic peak, followed by a stabilization phase, then a return to a background level. The stabilization phase has a generally parabolic current shape, and is performed in a current-closed loop manner until a transition point. Resulting weld performance is improved, with a globular-like transfer mode, reduced shorts and enhanced arc stability.

    摘要: 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). The antennas (40) can be low- profile planar antennas (40), either linearly or circularly polarized, which can be advantageously mounted to a housing while limiting undesirable contact with the environment and therefore to limiting the potential for damage.
