The socket welding machine ESI 4000 carries out an electric socket welding process in which
pipes are welded to a fitting.
The prepared pipes are fed into the socket and then aligned and clamped in the clamping tool.
The contacts are plugged to the socket.
The sockets are furnished with a bar code, it will be read in with the bar code reading pen or
manually entered at the machine.
The welding process is started, the welding joint is heated (Heating up), and afterwards the
machine automatically shifts.
The welded pipe cools down without tension. (Cooling down)
The welded pipe can be unclamped, the welding process is completed.
