由哈尔滨微电脑焊接设备技术开发公司研制生产的一种新型焊机WSM-300AC/DC交直流两用钨极氩弧焊、手弧焊、电弧点焊机、于1986年12月10日在哈尔滨市通过了由哈尔滨市科委、哈尔滨市经委联合主持的产品技术鉴定。 WSM-300AC/DC焊机具有一机多用,操作使用方便的特点;在各功能下均能够输出交直流脉冲电流,并且频率、脉宽均可调。该焊机的交流输出波形为工频方波,正负半波比可调,对于铝及铝合金的焊接具有独到的
From Harbin microcomputer welding equipment technology development company developed and produced a new type of welding machine WSM-300AC / DC AC and DC TIG welding, hand arc welding, arc spot welding machine, on December 10, 1986 in Harbin Adopted by the Harbin Municipal Science and Technology Commission, Harbin City Economic Commission jointly presided over the product technical appraisal. WSM-300AC / DC welding machine with a multi-purpose machine, easy to operate features; in all functions can output AC and DC pulse current, and the frequency and pulse width can be adjusted. The AC output waveform of the welder square wave frequency, positive and negative half-wave ratio adjustable, for aluminum and aluminum alloy welding has a unique
