A holder for a spot welder tip dresser with an adjustable cutting rate is disclosed. The holder includes a cutter to cut a spot welder tip, a holder body provided at both ends thereof with a pair of guide surfaces to guide the spot welder tip, an adjusting liner configured to come into close contact with the cutter and which adjusts a protruding length of the cutter, and a clamp to fix the adjusting liner and the cutter to the holder body. A cutting rate of the spot welder tip is adjusted according to a thickness of the adjusting liner. Accordingly, reduced maintenance costs are accomplished by maintaining a constant cutting rate of a tip and forming an even welding spot at the tip, and reduced overall welding time and improved welding quality are accomplished owing to rapid tip cutting and formation of an even nugget at the tip. |
