Selection of aluminum welding machine

Because of the low melting point of aluminum and a dense layer of high temperature resistant oxide film on the surface, it is required that the aluminum welding machine must have the function of removing the oxide film, and the melting point of aluminum is low, and the thin plate is more. It is necessary to complete the welding and not burn through the parent material. Therefore, the welding aluminum can only choose the AC and DC arc welding machine and the pulse gas protection welding machine.
