Gantry type controlled by AC transducer to assure the stability and high efficiency, Automatic arc-tracing centralizing device.
LHA auto submerged arc welding machines are gantry-type machine designed specially for welding H/I beams. The machine is most popular for manufactures of steel fabrication due to its speed and options available.
Gantry Movement instead of beam motion. Gantry moving speed is controlled by AC transducer to assure the stability and high efficiency. Automatic arc-tracing centralizing device is applied to avoid the aberrancy while welding. The machine is provided with flux feeding & recycle device. By recycling the flux it is possible to save the cost.
