First of all, you need to correctly define the range of tasks that will be solved with the help of the purchased device. If the device is needed for one-time work around the house with small-diameter polypropylene pipes or for upgrading existing utility networks in a house or apartment, then there is no point in choosing expensive equipment. A high-quality, inexpensive device of medium power will cope with such problems. The main thing is that the owner is comfortable working with it. Well, in the case of planned regular use, intensive load - it makes sense to look for a more serious device.
Welding machine power. Usually, for household needs, devices with a power not exceeding 1 kW are purchased. It should be correctly understood that any welding machine heats up to the required melting temperature of polypropylene, and the power indicator in no way affects the quality of pipe connections. It is just that a more powerful device is brought to a state of readiness from the moment of switching on somewhat faster. In addition, after giving off a certain amount of heat to warm up the parts being connected, any device requires a certain time to replenish this "loss". It is clear that cyprus mobile database more powerful equipment this interval will be shorter. But this is noticeable, rather, during "conveyor" professional installation, and in home use, when welding any joint is preceded by marking and fitting, the difference is unlikely to be noticeable.
For a house or apartment, a welding machine with a power of 0.7-1.0 kW is quite sufficient.
Higher power ratings will also be required when installing large diameter pipes – from 75 mm and above. In practice, in a house or apartment, you do not have to deal with such details.
The next parameter is usually directly related to the power – the maximum permissible diameter of the welded pipes. There is no need to repeat much – most home craftsmen operate with three sizes – 20, 25 and 32 mm, and the devices of medium power, as a rule, are capable of welding parts up to 63 mm.
Accordingly, the device is usually equipped with couplings and mandrels. However, household-class devices often have only three pairs of heating nozzles in the kit - from 20 to 32 mm, and this is quite sufficient.
By the way, when choosing a tool, special attention should be paid to the quality of such equipment. Conscientious manufacturers accompany their equipment with couplings and mandrels with a Teflon coating (may be designated in the passport by the abbreviation PTFE). This non-stick coating prevents melted plastic from sticking to hot elements, which significantly simplifies and speeds up the work.
