Features of the socket welder

The Högert socket welder 850W is a powerful welding device for professional use. The handy device combines a compact design with maximum usability. The high-quality housing made of blue ABS plastic is robust and shock-resistant and has a simple operating unit with four buttons and an easy-to-read LCD display. The display shows the set temperature, the current temperature during heating and the residual heat via red illuminated digits. Two control LEDs provide information about the operational readiness. For easy handling, the welder can be slid onto the supplied stand and always ensures a secure footing, even when heating thicker pipes of 40mm, 50 or 63mm.

The generously dimensioned heating plate on which up to three pipe adapters are screwed is heated to the set temperature very quickly due to the high heating power, so that the welding of plastic pipes can be carried out without long waiting times. With the seven pipe adapters in the sizes Ø16, Ø20, Ø25, Ø32, Ø40, Ø50 and Ø63mm, all diameters used in hydraulic and pneumatic pipe installation are included. Each pipe adapter consists of a heating mandrel, a heating sleeve and a threaded screw made of stainless steel. To ensure that the heated plastic pipes can be easily inserted and removed from the pipe adapters, they are all provided with a very high-quality PTFE coating that prevents the plastic from sticking. The necessary tools for tightening the screws, consisting of an Allen key and a Phillips screwdriver, are also included in the high-quality metal case and are included in the delivery programme.

For safe handling, the unit is equipped with a residual heat indicator that can be read via the LCD display. In addition, the socket welder has a safety mechanism that protects the unit from operating at temperatures that are too low. The recommended operating temperature is between 0°C and 40°C. For a high-quality brand product that is also aimed at commercial users, it comes with a flexible cable with earthing contact plug, which is suitable for construction sites.

Welding of pipes with the socket welding machine from Högert

Inserting the tube adapters
The case set contains seven pipe adapters, each consisting of a heating sleeve for heating the plastic pipe and a heating mandrel for heating the fittings, sleeves and fittings. These are clearly arranged in the case according to size and can be easily removed from the holder provided. The head plate of the socket welder has three separate holes which are used to hold the adapters. Inserting the pipe adapters is child's play. After the desired size has been removed from the case, the screw must be completely loosened and inserted through the hole provided in the heating mandrel, as well as the desired receptacle in the head plate of the heater. On the opposite side of the head plate, the heating sleeve, which has a high-quality brass thread, is turned onto the screw until it rests firmly on the head plate. An Allen key included in the set is used to tighten the screw. To avoid errors, all tube adapters have an engraved size indication. This ensures that the wrong size is not used or that different sizes are used for sockets and mandrels.

Depending on the size of the required pipe adapters, up to three places can be occupied at the same time. This is particularly helpful when pipes with different diameters, reducing sleeves or T-pieces with diameter reduction are to be processed during pipe installation. This means that in most cases there is no need for complete cooling and replacement of the pipe adapters, but only one pipe with the corresponding fitting may be heated at a time.

WARNING: Please ensure that the mains plug is disconnected and the unit has cooled down sufficiently before inserting the tube adapter.

Setting the welding temperature
The welding temperature can be set to the exact welding temperature in steps of one, tens and hundreds. The easy-to-read LCD display shows the current temperature and the ALM indicator light signals when the set temperature has been reached. Another control lamp, labelled OUT, flashes as long as the tube welder is in heating mode. This light also flashes if the unit heats up again in the meantime to maintain the set temperature. Especially when the pipe is put into the heating socket and the fitting is put onto the heating mandrel, this can lead to a minimal drop in temperature, which causes the unit to heat up again. Due to the high performance of the Högert socket welder, both the heating up after commissioning and the intermediate heating to reach the welding temperature again are completed within a very short time.

The actual welding temperature, which can be set very easily using the four arrow keys, depends on the plastic that is to be welded together. For our white PP-R pipes, the recommended welding temperature is 260°C. However, this temperature is too high for welding PVC pipes, so a lower temperature must be set on the machine. The exact temperature required for welding thermoplastic pipes can usually be found in the product descriptions of the dealers and manufacturers.

Heating of pipe and connecting element
As soon as the desired welding temperature has been reached, which is indicated by the control indicator lighting up, the plastic pipe can be inserted into the heating sleeve that matches the diameter. At the same time, the fitting, for example a connecting sleeve, should be placed on the opposite heating mandrel. The welding time for heating the plastics, as well as the insertion depth, varies depending on the material and diameter. The operating instructions contain a clear table with guide values for welding plastic pipes. However, exact information should always be obtained from the manufacturer or dealer if this important information is not available directly on the product page. For our PP-R pipes, this information, as well as the cooling time, is always included in the additional information and in the data sheets, which we make available for download.

WARNING: Heat-resistant work gloves should be worn as a matter of urgency to prevent burns from contact with the head plate or the pipe adapters.

Making the welded joint
After heating, the pipe can be inserted into the fitting. This should be done immediately, without much delay. Make sure that the pipe is inserted straight and without turning it until the required insertion depth is reached. The welded joint should then cool down.

Changing the tube adapters
Changing the tube adapters is done in the same way as inserting them, with the difference that the already mounted adapters must be removed from the head plate in reverse order. It is very important that the unit cools down sufficiently beforehand and that the mains plug is disconnected from the socket in order to prevent accidental activation of the heating process. Once the tube adapters have been changed, the unit can be reconnected to the mains and the working temperature for welding can be set.

The removed tube adapters should be cleaned if necessary before they are stored again in the intended place in the case, so that they can be used again for the next application. No metal objects or wire brushes should be used for cleaning, as these can damage the PTFE non-stick coating.

NOTE: Before commissioning, the user manual should be read. To avoid damage to the unit or personal injury, the safety conditions of the manual must be strictly observed!

Care and maintenance of the welding machine for plastic pipes

The socket welder should be checked for damage to the mains cable after and before each use to ensure that the cable insulation has not melted through contact with the heating head. In addition, the casing, the heating head as well as the sleeves should be cleaned of any build-up after each use, after the unit has cooled down completely and the mains plug has been removed from the socket. This ensures smooth operation of the appliance. The housing, as well as all other components, can be cleaned of dust and dirt with a dry, soft cloth or a brush with plastic bristles. Never immerse the unit in liquids, e.g. water, for cleaning purposes in order not to damage the electrical components or run the risk of receiving a life-threatening electric shock during commissioning. Electrical equipment should never be opened and should only be repaired by authorised personnel.

Maintenance work is being carried out. There is a risk of severe burns or electric shock!
