Component
Ac pulse spot welder is composed of step-down transformer, current regulator and cooling system, welding wire, handle and other accessories.
Characteristics
Ac pulse type spot (convex) welding machine is the use of ordinary mains, through the transformer to reduce the voltage and increase the current. This low voltage and strong current is then sent through the electrode to the welding part of the joint, at the joint due to resistance to produce resistance heat, the metal is molten by this heat to the workpiece welding.
Pre-loading stage - the electrode drops to the current on stage to ensure that the electrode presses the workpiece so that there is appropriate pressure between the workpiece.
Welding time - welding current through the workpiece, heat generation to form molten core.
Maintenance time - cut off the welding current, and the electrode pressure continues to be maintained until the molten core solidifies to sufficient strength.
Rest time - the electrode begins to lift until the electrode begins to drop again, starting the next welding cycle.
Advantage
Safe, fast and environmental protection: smooth pressure, fast welding speed. Welding time is short, only 0.02 seconds; No need to add lead and other filler metals, low energy consumption, high efficiency. Enhanced fuselage, stable welding, energy saving, lasting operation. Microcomputer controller, easy to operate.
Strong output: strong output, uniform conduction. Adopt high quality and high permeability silicon steel sheet refining welding transformer, powerful output, can weld thickness of 7mm+7mm low carbon steel and stainless-steel plate.
Three stage discharge: improve the welding stability, special materials can be preheated, shaping, tempering treatment, to avoid the virtual welding caused by current diversion, welding, especially suitable for high carbon steel, special coated metal plate.
