Might anyone have an ultrasonic welder for sale or know of a source for new machines? Preferably desktop style with a weld length capable of larger polyester encapsulations. I have also considered the handheld ultrasonic welder. Opinions regarding handheld vs desktop welders would be much appreciated!
