  • High Power - Micro Resistance - Advanced CD Spot Welder

    Sunstone’s high power - advanced - dual pulse CD 1200 offers many capabilities including weld monitoring, SPC tools, and a large capacitive touch-screen interface. The touch-screen interface provides easy access to all weld parameters. In addition, you get a visual of the weld waveform graph, weld histograms, alarms, warnings, and even on-screen documents and videos. For automated production settings, the welder has multiple PLC protocols. You can also set up multiple machines in a simplified way thanks to the clone feature. Cloning allows you to copy all your parameters/settings and easily export/import them to other machines.

  • Micro Resistance - Single Pulse CD Spot Welders

    Sunstone’s Single Pulse resistance spot welders are engineered to provide a wide range of welding flexibility for micro spot resistance welding. They can provide as little as 0.1 watt seconds (joules) of energy for welding microscopic wires and parts, or can deliver up to 200 (depending on the model) Joules for stronger welds. Thanks to a simple user interface, these welders are versatile and easy to use for many micro spot resistance welding applications. The welder can be operated at up to 120 welds/minute. These welders are versatile and easy-to-use for many fine-spot resistance welding applications. The welder interface lets users quickly select weld settings for a wide variety of welding applications.

  • Micro Resistance - Dual Pulse CD Spot Welders

    The dual pulse industrial capacitive discharge (CD) spot welder provides a substantially larger amount of weld energy combined with a finer range of power adjustment. As with Sunstone's other spot welders, the CDDP welders produces clean, strong welds. Pulse one heats the weld area to eliminate surface contaminants and seats the welding electrodes. Pulse two then makes a strong, secure weld. Both pulses occur within milli-seconds.

  • High Power - Micro Resistance - CD Spot Welder

    The  CDDP industrial spot welders provide a substantial amount of weld energy along with a fine range of power adjustment. These welders provide up to 1100 watt seconds of energy for thicker, more conductive, and highly-resistive materials.  Weld energy can be adjusted by increments of 10ws making it extremely versatile for a variety of industrial spot welding applications.
