How to operate butt fusion machine
Open the frame, put the hot spring pipes and fittings to be welded in the frame, leave enough distance for milling and heating flanging to make them at the same horizontal line, and hold up the parts outside the frame with supports and then tighten them. Set the heating plate temperature and heat absorption time according to the requirements of the relevant welding process. Place the milling cutter on the frame, turn on the switch, push the gear lever forward, mill the end faces of the pipe and pipe fittings, remove the milling cutter, close it again, make sure that the pipe is at the same level, and then wipe it clean with alcohol. Set the temperature of the heating plate, place it in the rack after the temperature reaches, and then close it, adjust the pressure to the specified welding pressure value, wait until the pipes on both sides are evenly flanged, unload to the heat absorption pressure, and press the heat absorption time at the same time. Pay attention to the pressure changes during the heat absorption process. When the heat absorption time is reached, the machine will sound an alarm. You should open the rack, quickly remove the heating plate, and then quickly close the rack and press the cooling time at the same time. Here you should pay attention to the closing machine After the rack, push the lever forward and keep it for about 2 minutes, and let it go after the pressure is stable; when the cooling time is complete, the machine will also give an alarm. At this time, the pressure is removed first, and then the rack bolts are opened, and the welding is completed.
