Welding Checker SP-3288/3290

  • Model SP-3288 is a handy type welding meter of secondary current and welding time for all kinds of resistance welding.
  • Sensor is MEKANO patented toroidal coil for precise current detection.
  • Measured data is digitally indicated in the display and stocked in built-in memory.
  • RMS effective value calculated at each half cycle or Peak value of welding current is displayed together with welding time and conduction angle.
  • In case of capacitor discharge type welder, it measures and displays peak value of current and time(mSec) to peak current or time(mSec) to the end of current application



  • More compact lighter body and touch key is improved for easier operation.
  • Measured data of maximum 100counts are stocked in built-in memory .
  • Wide range for measurement (Current: Max. 99.9kA, Time: Max. 999.5CY 2000ms) /
  • The unit displays measured data; “Count No.”, “Current (kA)”, “Welding time (cycle / ms)”
    and “Conduction angle”.
  • Additional new functions support measurement of designated time scope for any current type
    and designated pulse number for multi-pulse current application.

Data Output : (SP-3290)

  •  SP-3290 has USB port for transfering the measured data as below to PC.
  •  Free software for PC application is available at Spotron website.
