2. Flexible activity: The upper electrode is flexible, and there is no need to move the workpiece during welding, improving production efficiency; At the same time, the welding platform can be lifted and lowered within a certain range, facilitating the welding of products of different shapes and heights.
3. Firm welding points: During welding, the pressure is generated by the cylinder, ensuring a balanced and consistent welding pressure for the workpiece and ensuring welding strength.
4. Easy to use: The operation is simple and convenient. When welding, simply press the switch, and the operator can easily operate it with or without experience.
5. Scope of application: Used for welding metal plates such as cold plates, galvanized plates, stainless steel plates, etc.
6. Applicable industries: chassis cabinets, elevators, electrical cabinets, automobiles, steel and wood furniture, kitchen appliances, and other industries.
