1. A weld monitor system for use with a resistance type welding machine having a welding electrode and a pressure applying compressive member which applies pressure to parts welded by the welding machine, the weld monitor system operative to monitor and record currents and pressures by which parts are joined by welding performed by the welding machine, and to monitor pressure applied by a compressive member to parts welded by the welding machine, the weld monitor system comprising:

  • a current transformer coil for measuring current applied to welding electrodes of the welding machine,at least one welding pressure transducer for measuring pressures applied by an electrode of the welding machine to parts joined by welding performed by the welding machine,at least one compressive member pressure transducer for measuring pressure applied by a compressive member of the welding machine to parts welded by the welding machine, anda recording device for recording values measured by the current transformer coil and the pressure transducers.
