A special attention was given to improving the design of the inverter: in particular, the board itself was additionally plated with tin. Thanks to the high-quality board and powerful power transistors, the guaranteed service life of the device is significantly increased - at average loads it can withstand more 100,000 work cycles.
In turn, the efficiency of the tool is 80%, and to maintain the optimal temperature regime, all important parts are cooled by a fan. Depending on the conditions, the welding machine has two ways of connecting, let's consider them. 1 A direct connection - assumes a negative polarity in the holder and a positive in the welding workpiece.
2 A reverse connection - on the contrary, this method is effective in the processing of thin-walled parts and when using electrodes with a basic coating. The advantages of the SAB-258 DPB include economical power consumption (the power consumption of the device is 5.5 kW), noiselessness, easy ignition of the electrode and the creation of a welding seam.
In addition, this model is characterized by its mobility: the weight of the device is only 3.8 kg, and for working in remote locations the set includes wires with a length of 2.5 and 3 m. Due to its characteristics, SAB-250 allows inexperienced welders to perform their work qualitatively. Voltage power supply (V): 220. Rated welding current (A): 250.
Duty cycle (%): 80 (35°). Welding current range (A): 20 - 250. Electrode diameter (mm): 1.6 - 4.
