Cutting: Use a special cutter to cut the pipe according to the required size. When cutting the pipe, be careful not to run the line and slowly screw the blade in, do not advance too sharply, it will damage the blade. When the cutter is difficult to rotate, the cutter should be rotated in the opposite direction, the blade should be removed, and the line should be re-run. Preheating: Adjust the preheating pressure to the pressure required for welding with the PPH pipe hydraulic control valve. Adjustment method: lock the heating pressure relief valve, push the hydraulic operating rod forward, and watch the pressure gauge display the pressure. When the required pressure is not reached, loosen the heating pressure relief valve, make the pressure gauge display drop to zero, readjust the hydraulic regulating valve, and then lock the heating pressure relief valve until the pressure is expressed to the required pressure. Use the temperature setting panel on the welding machine control platform to set the temperature of hot-melt welding, and control the temperature of the heating plate to match the melting of the welding surface. Red shows the set temperature, green shows the current temperature, when the red light on the panel jumps to the green light, the hot melt welding can be carried out. PPH hot melt temperature is generally set between 195 ℃ ~ 205 ℃.
