How to adjust the welding die of ws 250a welding machine
King welder WS 250A is a common welding equipment, which is suitable for all kinds of welding tasks, including welding dies. Pay attention to the following aspects when adjusting the welding machine for mold welding:

1. Select the appropriate welding current: the selection of welding current should be determined according to the material and thickness of the mold. Generally speaking, the welding current should be moderate, too high will lead to overheating, too low will lead to unstable welding. The appropriate current can be selected according to the welding manual or experience.

2. Adjust welding voltage: The adjustment of welding voltage is also very important. Too high voltage will lead to overheating of welding, and too low voltage will lead to unstable welding. The best welding voltage can be determined by trial welding.

3. Select the appropriate welding material: the selection of welding material should be determined according to the material of the mold. Generally speaking, the welding material should be similar to the mold material to ensure the firmness and durability of welding.

4. Preparation of welding surface: It is very important to prepare the welding surface. The dirt and oxide on the surface can be removed by grinding or cleaning to ensure the welding quality.

5. Control welding time and speed: The control of welding time and speed is also critical. Too long welding time will lead to overheating, and too short welding time will lead to unstable welding. The welding speed should be moderate to ensure the uniformity and firmness of welding.

6. Pay attention to welding position and angle: The selection of welding position and angle is also very important. The best welding position and angle should be determined according to the shape and structure of the mold to ensure the quality and beauty of welding.

In short, it is necessary to select appropriate welding current and voltage, prepare welding surface, control welding time and speed, and pay attention to welding position and angle, so as to adjust welding machine WS 250A for mold welding. Through reasonable adjustment and practice, high quality welding effect can be obtained.
