System: DCD320 – DC and CD resistance welder (high precision power supply)

MWH2000 – 2000g parallel gap micro weld head Thermo-compression electrode (flat rectangular tip) The MWH2000 parallel gap weld head is capable of using thermo-compression electrodes for situations requiring a weld through material such as magnet wire that can’t be grounded (polyimide coating). We used a tungsten thermo-compression electrode with a rectangular tip to weld the wires to the gold plated pads. We used double sided tape to keep the ceramic plate firm against the base. The force is set to 1500g for the welds pictured.

The DCD320 is set with pulse 1 off, pulse 2 at 45ms, and peak voltage at 2.0v to attach the 34awg magnet wires to the gold pads. These settings result in good weld strength and the tails can be removed using tweezers. Further experimentation with force, length and energy could yield even better results as you work with your product.

Summary: The DCD320 power supply and MWH1000 weld head provide operators with the ability to fine tune energy settings and weld durations for strong joints without damaging substrate material. Using thermo-compression electrodes enables the coated wires to be welded without being stripped first.

  • Linear DC

    The Sunstone Linear DC welder is a completely unique resistance welding system with closed-loop feedback. Utilizing new patent pending technologies, the Linear DC welder has the power of a High-Frequency Inverter and the precision of a Linear DC. As mentioned, this is a completely unique product. It isn’t an HF welder since it does not require an external transformer, and it isn’t like typical Linear DC welders because it doesn’t use transistors to control the energy output. Yet, this product is able to perform the same functions as both of these technologies, and in most cases it has capabilities that exceed those of other HF or Linear DC welders – offering high repetition rates, fine low-energy control, and short or long weld times – without any of the drawbacks and inconveniences.
