FAQ – Heavy-Duty Spot Weld Gun
Q1: What is a heavy-duty spot weld gun used for?
A heavy-duty spot weld gun is designed for large sheet metal and structural parts that require high electrode force and stable weld quality, commonly used in automotive body-in-white and heavy fabrication.
Q2: Why is water cooling important in resistance welding guns?
Water cooling prevents overheating of the transformer and welding arms, ensuring consistent current delivery, longer component life, and stable weld nuggets.
Q3: Can the welding arms be customized?
Yes. Welding arms can be engineered with different lengths, bends, and angles to match specific workpiece requirements.
