This is a self-aligning machine, suitable for welding ducts for the transport of water, gas and other fluids under high pressure, up to Ø1000 mm. The DELTA 1000 can weld fittings such as bends, tees, branches and flange necks. This is possible because the 3rd clamp can be anchored to the 1 st and 2nd (movable) and slide along with the pipe. The fitting must be locked in the 4th clamp. Necks with a highly reduced tang can be welded with the help of a special tool (on request), applied to the clamps.
