Linear DC precision welders
Sunstone has designed a completely unique closed-loop feedback resistance welding system. Utilising the latest Ultra Capacitor technology, the UC Linear DC welder has the power of a High-Frequency Inverter and the precision of a Linear DC.
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.
When it comes time to weld with the UC Linear DC, users have from 10-2500 amps of weld current. The weld time duration can range from 0.1 up to 1000 milliseconds and is also adjustable by 0.01ms increments. In addition to setting weld current, voltage, or power, and the weld time for upslopes, welds, and downslopes, the UC linear DC can introduce high-frequency agitation to each of these weld parameters. This agitation feature provides additional weld penetration, more uniform metal crystallization, stronger weld joints, and can facilitate stronger weld joints with lower overall heat input.
