Сварочный аппарат EPA MMA-250FI-2

Are widely used in the household and in the performance of construction production works. Now you can pick up the equipment and use it successfully even in the absence of skills. There are four types of welding equipment. The transformer – outputs alternating current. It is easy to use, has a low cost, long-term operation. It is not suitable for beginners, has an unstable arc, splashes of molten material remain around the processing site, which requires further cleaning. The rectifier changes the alternating voltage to a constant one. It works quietly, the connecting seam is smooth, the arc is stable, used with different metals. Overheating is possible with prolonged use, the stability of the mains voltage is required. The inverter produces a constant current. It has a constant arc even with voltage fluctuations, the process can be automated, works with all metals, the welding seam can pass vertically and horizontally, on the floor, walls or ceiling.
