Spot welding electrodes

[EdBerger]

Does anyone know where I can buy resistance spot welding electrodes for welding aluminum sheets with characteristics:

1). Electrode with domed tip Ø = 22 mm, length = 55 mm, hemispherical radius = 75 mm in conf. British Standard 807

2). Chemical composition in conf. ISO 5182/1991 code A 1/1 and A 1/2 (CuTeP, CuCd1, CuAg 0,1P, Cu-ETP)



Thanks
