【摘要】 对我校研制开发的便携式逆变焊镀充电多用机的外特性进行了研究，该机与其它同类逆变焊机相比，是一种同时具有陡降的恒流特性和平直的恒压特性的多外特性多用机，不仅可用于手工电弧焊、ＴＩＧ 焊，而且可用以刷镀、充电等，具有高效、节能、体积小、重量轻和性能优良的特性。该机电路设计简单，可靠性高，在实际生产应用中取得了较好经济效益。更多还原

【Abstract】 This paper has a study on the outer characteristic ofthe portable multi function machine with inverter welding , brush plating and charging developped by our college . Compared with other kin inverters,it is a multi outer characteristic and multi function machine ,with a constant electricity falling steeply and plain strainghtconstant voltage characteristic meanwhile .Not only used for manualarc welding ,TIG welding ,butfor brush plating ,charging etc ,the characteristic of high efficency ,spare en erge ,little volume,light weight and admirable function ,Its circut,designed briefly ,have a high reliance.In actual appliances,it achieves better economic benefit.更多还原
