The use of hot melt hydraulic butt welding machine is a complex resistance butt welding machine. It is designed and manufactured by Nova Welding based on the experience of the previous five generations of machines. It has many uses and more complex operations. It needs to adjust air pressure, water flow, welding parameters, etc. The specific operations are as follows:

1. Open the water valve, and the flowmeter on the right side of the welding machine can display the flow of cooling water after the water is supplied to ensure that the cooling circuit is smooth and meets the cooling requirements.

2. Open the air valve and observe whether the indication of the barometer on the triplet of the air source device at the inlet is normal.

3. Pull up the air pressure regulating valve on the operation panel to regulate the air pressure, so that the clamping cylinder and the upsetting cylinder can produce the required clamping force and upsetting force. There is a red button on the solenoid valve of the pneumatic circuit. Press the button to adjust the mechanical components without power supply. Press the small red button to rotate 90 degrees clockwise to lock the cylinder. The upsetting force is an important welding parameter, and it should be repeatedly debugged during the initial sample.

4. When adjusting the cylinder, if the action is too violent, adjust the throttle valve at the air inlet of the cylinder to control the air inlet speed,

5. Install the welding die and tighten the fixing bolts to tighten the die. Adjust the clamping mechanism and die position according to the welding requirements. Rotate the limit nut in front of the horizontal top cylinder to adjust the horizontal upset distance.

6. Turn on the control power switch, and the power indicator light should be on. During adjustment, the manual/automatic knob can be set to the manual position, and the left and right cylinders and upset forging cylinders can be controlled manually by pressing the button below.

7. The machine can be configured with a travel switch, which will stop welding when the welding time is up or when the travel switch acts.

8. Travel switch: close the welding current after top connection. Opening the upset atmosphere can effectively improve the butt joint quality.
