Our range of open welding heads allows you to make very high-quality welds in minimal space. On these heads,you will find a mechanical tracking system to keep a constant arc height. The torch can tilt to weld at an angle.This type of machine can be used to weld carbon steel tubes. Open heads offer very wide welding possibilities thanks to the inclination of the torch and the addition of filler metal. The clamping range is achieved without the addition of jaws. The tracking system is by roller so as not to scratch the tube. All the parts in contact with the tube are made of stainless steel so as not to contaminate it. The MWG-170 open frame automatic orbital welding machine is equipped with an external wire feeder together.
