Equipped with a microcomputer controller and an LCD display for parameter visualization, the DTN1-75KW customizable pneumatic spot welding machine offers precision, clarity, and ease of use. During the welding process, it produces minimal sparks while ensuring robust welding results. Ideal for welding a variety of materials including hot and cold plates, stainless steel plates and wires, as well as nuts and other workpieces, this machine incorporates an all-copper transformer and wide-voltage technology. The voltage can adapt automatically within a 20% range, adding to its versatility. Operation of the welding machine is straightforward under normal conditions, allowing adjustments to pressure time, welding current, welding duration, maintenance interval, and rest periods directly through the microcomputer controller.
