1. What is a welding machine?
An electric welder is a device that converts electrical energy into heat energy, melts and welds metal materials together through a high-temperature arc. It can provide stable current for welding operations and ensure the quality and strength of welded joints.
2. Main types of welding machines
Manual arc welding machine: It uses electrode rods as filler materials and is suitable for welding a variety of metals. It is the most common welding machine.
Gas shielded welding machine: Uses inert or semi-inert gas to protect the weld and prevent oxidation. It is suitable for welding stainless steel, aluminum and other metals.
Submerged arc welding machine: uses arc to weld under sand and slag, suitable for welding large components or thick plates.
TIG welding machine: uses inert gas tungsten electrode welding, suitable for high-quality welding requirements.
3. Working principle of electric welding machine
The working principle of the electric welding machine is to convert the working current into heat energy, generate a high-temperature arc, melt the welding electrode and workpiece, form a molten pool, and form a weld after cooling. An arc is caused by the passage of an electric current through a gas between two electrical conductors of different potentials.
4. Precautions when using electric welding machine
Safety: When welding, be sure to wear special protective glasses and welding gloves to avoid arc light damage to the eyes and high temperature burns to the skin.
Environment: Ensure the working environment is well ventilated to avoid the accumulation of toxic gases.
Power supply: Ensure that the power supply connected to the welding machine is stable to avoid the impact of voltage fluctuations on welding quality.
Equipment inspection: Before each use, check whether the circuit and equipment of the welding machine are intact to ensure the safety and stability of the equipment.
Welding machines are indispensable tools in modern manufacturing and construction industries. Using it correctly and safely can ensure welding quality and extend the service life of the product. Whether you are new to the industry or a seasoned expert, understanding the basics and operating techniques of a welder is key to ensuring work efficiency and safety.
