An MMA welding machine (manual metal arc welding machine) is a process that uses arc discharge to produce high temperatures to fuse metals and achieve welding. The system mainly includes a power supply unit, a welding clamp, a grounding clamp, and an electrode. It generates an arc through alternating current or direct current to reach high temperatures, melting the electrode and base material to form a strong weld. The outer coating of the electrode decomposes at high temperature, producing protective gas and slag, isolating the welding pool from the air, preventing oxidation, and ensuring welding quality.
MMA welders are known for their high environmental adaptability, operational flexibility, and cost effectiveness, making them indispensable in industries such as construction, industrial maintenance, vehicle manufacturing, outdoor engineering, and small-scale production.

MIG welding machine (Metal inert gas welding machine) is an efficient and versatile gas arc welding equipment, which belongs to the category of GMAW, Gas Metal Arc Welding, designed for fast and stable metal connections. Widely used in industrial manufacturing and maintenance fields. It uses an inert gas (such as argon, helium, or a mixture of gases) or an active gas (such as CO2) as a protective medium and enables automatic or semi-automatic welding through continuous wire feeding technology. MIG welding efficiency is high, strong adaptability, suitable for aluminum, magnesium, copper alloy, stainless steel, and low carbon steel and other metals, equipped with a digital inverter power supply, output current accurate and stable, soft arc and less splash, uniform weld beautiful, easy to operate.
In recent years, with the development of digital technology, MIG welding machines have gradually integrated automatic parameter matching, welding seam tracking, and other intelligent functions, further improving the welding accuracy and becoming an indispensable and efficient connection technology in the modern manufacturing industry.

Tungsten Inert Gas Welding Machine (TIG), also known as Gas Tungsten Arc Welding (GTAW), is an industrial equipment designed to meet the requirements of high-precision welding, integrating high efficiency, stability and safety. Non-expendable tungsten electrode and inert gas (such as argon, ammonia) to protect the welding area, suitable for stainless steel, aluminum alloy, copper alloy, titanium alloy and other metal materials welding, widely used in automobile manufacturing, pipeline engineering and precision instruments and other fields. TIG welding machine adopts advanced inverter technology, stable output current, concentrated arc, precise control of welding pool, achieves uniform and beautiful weld, meets the strict process requirements of thin plate welding and complex structures.
TIG welding's position as a "metal sculptor" in the field of high-end manufacturing and restoration is irreplaceable.

A car battery charger is a device specifically designed to replenish the electric energy of the car battery and restore its power storage capacity. When the vehicle is stopped for a long time, does not turn on the lights, or the battery is exhausted due to extremely low temperature, the charger will connect the battery to convert alternating current into direct current. It provides current to the battery in a controlled manner, returning it to its normal operating state. The device is widely used in traditional fuel vehicles, hybrid vehicles, and some new energy models.
When using a charger, the following principles must be strictly observed: Choose an adapter that matches the type of battery (such as a 12V/24V system) and ensure the correct polarity when connecting the charger to prevent short circuits. Although the smart charger has overcharge protection, it is still recommended to useit  in a well-ventilated environment.
