Sunstone Linear DC Welder

 
 
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.
