2 . GENERAL INFORMATION 2.1 INTRODUCTION - This welding machine is a power source for arc welding, made specifically for direct current (DC). The specific characteristics of this regulation system (INVERTER), i.e. high speed and precise regulation, mean the welding machine gives excellent results when welding with coated electrodes (rutile, acid, basic). Regulation with the “inverter”... - Page 7 4. DESCRIPTION OF WELDING MACHINE 4.1 The unit is comprised of power modules which have been developed on a specially printed circuit designed to maximize reliability and reduce maintenance. 1- Power supply input (1~), rectifier group and balancing capacitors. 2- Transistors and drivers switching bridge (IGBT). It turns the mains rectified voltage into high frequency alternate voltage and permits power regulation according to the current/ voltage of the weld to be done.
