This is a self-aligning machine, suitable for welding ducts for the transport of water, gas and other fluids under high pressure, up to Ø 500 mm. The Delta 500 cab weld fittings such as bends, tees, branches and flange necks. This is possibile because the 3rd clamp can be anchored to the 1 st and 2nd (movable) and slide along with the pipe. The fittine 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. Available in 230 V and 400 V.
