A portable multifunctional field operation electric welding machine comprises a housing, output wires and a welding tongs, and is characterized in that: the electric welding machine adopts a small gasoline engine as power, a generator is driven by an output shaft of the gasoline engine to operate, and comprises a rotor and a stator, a multi-pole permanent magnet rotor is adopted as the rotor, the stator is coil windings, the permanent magnet rotor is mounted on the output shaft of the gasoline engine, the stator coil windings are connected with a three-phase rectification circuit, the positive and the negative output wires of the three-phase rectification circuit are connected with electric welding power output ends and low-voltage power output ends, and the electric welding power output ends are connected with the welding tongs. The electric welding machine is mainly characterized in that: direct-current output voltage is stable, carbon arcs are small during welding, welded end surfaces are smooth, welding rods can be utilized to the max, and the electric welding machine can be emergently used at places without alternating-current electricity, such as mountains, islands, bridges, railways, roads, oil wells, forest regions and ships, and under the conditions of natural disasters and no mains supply, and also can charge storage batteries.
Description
technical field [0001] The invention belongs to electric welding machines, in particular to a multifunctional electric welding machine for field work. Background technique [0002] With the development of the country's economic construction, the demand for arc welding power supply is increasing day by day, and its performance requirements are also constantly improving. At present, the electric welding machines that people use for welding work use the power supply after the power grid has been stepped down, generally 220V or 380V. Highways, oil wells, construction sites, forest areas and areas without mains power supply, or when geological disasters occur, when the wiring is inconvenient, the welding work is difficult to carry out, and a power supply with self-generating and welding functions is needed, so people have designed some diesel engines. Welding machines, but these welding machines need higher power diesel engines, which makes the work process need to move heavy di...
