I own a 400 amp AC/DC P&H arc welding machine. It uses a Mag-Amp...made on 1956...it has TIG capabilities..The mag-Amp response is fast enough to be suitable for this type of welder. The big transformer inside looks likea regular transformer, but has the extra 'control' windings. The 'control' crcuit uses a very amall amount of power to control this large welder....small DC circuit...번역 보기
