Moreover, a connector with the quality of on-land welding is formed, the welding efficiency is improved and the special portable miniature drainage cover is easy to popularize.

The invention discloses a multi-function precise aluminum welding machine circuit. The multi-function precise aluminum welding machine circuit is characterized in that the multi-function precise aluminum welding machine circuit comprises a high-power insulating transformer and an auxiliary insulating transformer, and the output end of high-power insulating transformer is connected to a rectification smoothing circuit; and the auxiliary insulating transformer is connected to a full-digitization operating faceplate, a 32-bit high-speed ARM controller and the like. According to the multi-function precise aluminum welding machine circuit, a plurality of welding modes can be achieved, and a continuous precise aluminum welding mode is an original function, so that the function that a thin aluminum plate can be precisely welded is achieved, the heat input quantity is greatly lowered, and deformation of a product is small; and the easy, convenient and quick operating property can be enough to surpass laser welding repair, so that the requirements of users for a larger range are met.

The invention discloses a method of controlling the arc strike of a carbon dioxide gas shielded welding machine by adopting digital pulse. The method comprises the steps of feeding gas for a welding gun; feeding a welding wire in a slow wire feeding mode; when the output voltage is detected to be 0 volt, outputting a 250-500 ampere short-circuit current pulse signal to the welding wire for arc strike; when the output voltage is detected to be smaller than 8 volts, switching from the slow wire feeding mode of the welding wire into a quick wire feeding mode, outputting a 250-500 ampere short-circuit current pulse signal to the welding wire to build a molten pool, and controlling an arc to be subjected to transition from arc strike to a stable arc. According to the method, the transient impact stress which is borne by a hardware power device is reduced, and the service life is prolonged; the arc strike time is shortened, the arc strike process is stable, the reliability is strong, and the arc strike success rate is high; the molten pool is built in the arc strike process, and thus a basic is established for normal, stable and reliable welding in the future. The invention further discloses a carbon dioxide gas shielded welding machine.
