Sunstone Linear DC Welders
The DC 5 is a precision DC waveform welding power supply, capable of precise power delivery. It has a maximum output of 5 volts, and can be adjusted to deliver as low as 0.1 volts. It has a digital readout that shows the weld length and volts delivered. The DC 5 is able to deliver up to 60 welds per minute. This unit is excellent for fine wires and metal sheets, such as ribbons. The DC 5 is the perfect choice for control and precision.
Sunstone’s micro welding solutions are perfect for microjoining and thermocompression bonding. When bonding small wires or ribbon from one connection pad to another, Sunstone’s new DC 5 - welder in combination with a low-force micro weld head is recommended as an optimal welding setup.
Applications
- Thermocompression and Microjoining Bonding
- Magnet Wire Welding

Sunstone has designed a completely unique closed-loop feedback resistance welding system that utilizes new technologies, giving the UC Linear DC welder the power of a High-Frequency Inverter and the precision of a Linear DC. It does not require an external transformer, so it isn’t an HF welder, and it offers a greater range of settings than a typical Linear DC welder, yet is able to perform the same functions as both, and in most cases exceed those of other HF or Linear DC welders – offering high repetition rates, fine low-energy control, and short or long weld times – without drawbacks.
The welder is highly adjustable to offer the most convenience to a wide variety of users allowing creation of custom software, ability to update and improve capabilities, features and functions effortlessly.
The UC linear DC can also introduce high-frequency agitation that provides additional weld penetration, more uniform metal crystallization, stronger weld joints, and can facilitate stronger weld joints with lower overall heat input.
