Heating and Cooling

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.

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.
