How to Use An Electrofusion Machine

If you're looking to join two pieces of polyethylene pipe together, then you'll need to use an electrofusion machine. This type of machine uses electrical current to heat up the ends of the pipes, which then melts the material and allows the two pieces to be fused together. Here's a step-by-step guide on how to use an electrofusion machine:

●Clean the ends of the pipes that you wish to join together. This is important in order to ensure proper adhesion between the pipes and the electrofusion fittings.

●Insert the electrofusion fitting into one end of the pipe.

●Join the other end of the pipe onto the electrofusion fitting, making sure that it's properly aligned.

●Connect one electrode of the electrofusion machine to the exposed metal surface of the fitting. Make sure that there is good contact between the electrode and the metal surface.

●Connect another electrode from the machine to one of your grounding rods or other grounding point. This is important for safety purposes.

●Turn on the power supply for the machine and set it to the desired voltage level (usually between 24 and 36 volts). Allow enough time for current to flow through the system - this will cause resistance heating within the fitting, which will melt both The plastic around The outside of The fitting And also The inside diameter Of The pipe itself. This process can take anywhere from.

How to Maintain Electrofusion Machine
 
1. Lubrication

Properly lubricating your tools can help extend their life span significantly, by helping to prevent corroding, premature wear, and overheating. There's no one-size-fits all approach when it comes to lubricating your tools, so consult the user-guide for each butt welder and piece of electrofusion preparation equipment.

2. Calibration

Regularly calibrating your tools will ensure their alignment is accurate, allowing you to undertake projects with as much precision as possible. The user-guide for each tool should outline how frequently calibration should occur, and how to undertake the calibration.On butt welders this includes pressure gauges, bleeding and balancing hydraulic cylinders.Electrofusion Machine are required to be calibrated every 12 months to ensure that the voltage/amps and time are measuring to spec. Advanced Piping Systems have an in-house lab and electrical engineers that calibrate all types of electrofusion welders and welding equipment. For more information call 130 362 229. To make it easy, we can arrange collection and delivery of your equipment, too.

3. Replacement of worn-out parts

A tool maintenance plan will help you keep on top of parts that may need to be replaced. Signs that your tools might need to be replaced include loose, cracked or splintered handles, deformed, or blunt blades, corrosion and caked dust and oils, cracked housing and frayed insulation or exposed wires.

4. A good clean

After a hard workout, your tools need to be cleaned to ensure continued optimum performance. More often than not, dust and other particles can be removed with a good brush-but when it comes to the tool's vents, it's best to use compressed air.

5. Tag-testing

All electrical tools need to be tagged and tested on a regular basis-and this includes the heater plate, hydraulic pump and fusion box.Often, when we send machines off-site, they could be there for two to three months at a time.It's critical that they are tagged and tested with at least another six months before they are due to be tested again.This is because cables can easily become frayed, and when you're using a heater plate of 240V, it could blow or spark, and you could receive a shock.

 

Selection and adjustment of Electrofusion Machine parameters

Voltage
The voltage of an electric fusion machine is generally between 50V-200V. The specific voltage selection depends on the melting point, conductivity and other factors of the metal. Generally speaking, the higher the melting point of a metal, the greater the voltage required.


Current
Current is one of the key parameters that affects the working efficiency of the electric fusion machine, and its size is generally between 50A-500A. Generally speaking, the current selected by the electric fusion machine is larger than the rated current of the metal conductor to ensure that the heat generated when the current passes through the conductor is enough to melt the metal.

Preheat time

Preheating time refers to the waiting time before formal heating. Generally speaking, the larger the metal conductor, the longer the preheating time should be. If the preheating time is too short, the surface temperature of the conductor will be uneven, affecting the heating effect of the electric fusion machine; if the preheating time is too long, time and energy will be wasted, and production efficiency will be affected.

Melting time

Melting time is the time required for the guide to melt. The melting time is related to the size, shape, melting point and other factors of the conductor. Melting time is adjusted to the specific conductor characteristics to ensure complete melting of the conductor.

Keeping time

The holding time refers to maintaining the electric fusion machine at a certain current and time after the metal is melted to maintain the liquid state of the conductor to facilitate the next process operation. The length of the holding time should be set according to the requirements of the subsequent process flow.

 

Precautions for Operating the Electrofusion Machine
 

The automatic Electrofusion Machine is mainly used for welding various plastic pipes and pipe fittings in new construction and reconstruction projects. It is necessary for operators to get professional training to avoid the risk of scalding during the welding process, and they can operate the electrofusion welding machine after they are qualified.

 

The daily maintenance of the Electrofusion Machine cannot be ignored, and it is also necessary to carefully check and proofread before using it. You should clean up the surrounding environment of the electrofusion welding machine to avoid equipment damage. In addition, heat-resistant gloves and eye protection equipment should be properly worn when operating.

 

You should check cables and power supply voltage. The power supply connected to the electrofusion welding equipment must meet the requirements. The cable and power supply voltage can only be powered on and used after repeated confirmation.

 

Electrofusion fittings cannot be disassembled in advance, you should open the package only during the formal operation. Before electrofusion, you have to make sure the surface of the fitting is flat and can be properly scraped with a professional scraper. The end of the pipe fitting should be cut at right angles with a pipe cutter and fixed. Besides, improper use will cause welding failure.
