Current Meters

General Information

There are only three primary variables to monitor the quality of a spot weld; Current, Force, and Time.  Surprisingly, many new standard and existing spot welders to not display Current.

The heat of a spot weld is directly proportional to the weld Current and weld Time.  It is inversely proportional to the weld Force.

Weld Time is displayed for adjustment on any solid-state weld control (in either cycles or milliseconds).  Weld Force is often adjusted by adjusting the pressure regulator (and having an understanding of the ratio of force to pressure).  Weld Current is often adjusted in percent (%).  Imagine trying to get a precision setting with a dimmer switch for a light bulb…

Current meters are either portable or fixed in place.  The offerings below are all portable.  They offer a means of reading Current and Time.  Some have additional features as well, like voltage reading, force transducers, USB downloads, PC software, and more.

These tools are specifically designed to be used with spot welding equipment.  They read the secondary weld current at the electrodes (or wherever you place the probe) where other meters can not.

We carry current meters from Miyachi, Entron, Dengensha, Tecna, and WTC.  Some of these manufacturers make many different models to choose from.  If you do not see what you need below, please enquire for more information.
