| 摘要 |
The modular welding gun (1) of the present invention, comprises the lower- and upper-clamp (2,3), joint (4) and cylinder (5) that are standard and do not change according to the type and size, and also comprises an electrode holder (6), welding electrodes (7) and the spacer piece (8), which change according to different areas of usage. By changing one or more of the spacer piece (8), electrode holder (6) and welding electrode (7) parts, according to the geometry of the area to be welded and to the sheet thickness, the capacity adjustments such as the length, clamp opening, electrode axis gaps and momentum can suitably be adapted, without changing such parts as the lower and upper clamp (2,3), cylinder (5) and joint (4).
