PPR welding machine FAQ
What is the correct welding temperature for a PPR welding machine?
The common range is 260–280℃, depending on pipe size and material. The joint should form a smooth and uniform bead.
How long should different pipe sizes be heated?
As a reference: 20–32mm: 5–12s; 40–63mm: 12–35s; >63mm: follow manufacturer’s table or testing.
Why does the PPR pipe joint leak or break after welding?
Main reasons: insufficient temperature, short heating time, dirty contact surfaces, misalignment, or inadequate cooling.
How to check if welding dies or the heating plate need replacement?
Replace if there are scratches, coating damage, uneven weld beads, or sticking issues. Minor dirt can be cleaned.
Can I use a generator to power a PPR welding machine?
Yes, but ensure stable voltage. Use a generator with at least 20–30% extra capacity and a voltage stabilizer to protect the control system.
Can a PPR welding machine weld PVC or HDPE pipes?
No. PPR welders are for PPR/PP-R pipes. HDPE usually requires butt fusion or electrofusion, and PVC uses a different method.
How do I choose the right PPR welding machine for my project?
Base your choice on maximum pipe size, workload, temperature accuracy, and portability. Small projects use 20–32mm units, large projects need digital or industrial models.
What are the daily maintenance steps and spare parts required?
Clean the heating plate after use, check wires and screws, replace heating rods and fuses regularly. Keep extra dies, heating elements, and screws on hand.
Troubleshooting FAQs
Why is my PPR welding machine not heating up?
Check the power supply, circuit board, and heater rod. If the circuit board is damaged, replace it with a new one.
Why does the PPR welding machine overheat or burn pipes?
This is usually caused by a faulty thermostat or wrong temperature setting. Calibrate or replace the thermostat.
Why are PPR pipe joints leaking after welding?
Leaks occur if the pipe is not heated long enough, the temperature is too low, or the joint is not aligned properly.
Why does the welding die stick to the pipe?
This happens when the die coating is damaged or dirty. Clean it with a soft cloth or replace the die.
Why is the temperature of the PPR welding machine unstable?
Unstable voltage or a damaged temperature sensor can cause this. Use a stable power source or replace the sensor.
Why does the PPR welding machine stop working suddenly?
The most common causes are a damaged circuit board, a broken wire, or a tripped overheat protection. Inspect components before reusing.
