◆【Spot welding knife】 The spot welding cutting machine is a double-sided rotary cutting machine blade, which separates the spot welding panel more effectively than the panel cutting machine. Use high temperature lubricants (not included) to maximize the life of the blade. High temperature lubricants are the best way to extend the life of the blade. When you start passivation, spot welding, and quickly cut clean, burr-free round holes, you only need to replace the blade. The spot welding knife can avoid this risk, it can be separated quickly, the blade is sharper, and the piercing ability is better.
