This series welding machines apply IGBT soft switch inverter technology. 3- phase input
volt are rectified by rectifier, inverted into HF AC, reduced by HF transformer, rectified and
filtered by HF rectifier, then output DC power suitable for welding. After this process, the
welder’s dynamical responsive speed has been greatly increased, so the
welder size and
weight are reduced noticeably result in energy saving. Power source enjoy sound
anti-fluctuating ability and high-quality performance during external context changes (As to
fluctuation in input power supply and extended welding cables).Easy to arc start, stable arc
length, pretty weld formation and capability of continuous regulation the current of welding,
arc-starting, arc force and time of down-slope as well as remote control availability add
significant values to customers. They can also perform down-slope, pre-gas flow and
post-gas flow function due to reasonable logic circuit design.
IN ARC Series arc welding machines output characteristic curve is as follows:
