welding copper strip 4

[trebor]

I have a job that requires butt welding of copper strip strip .110 thick x .500 wide. We have a miller syncrowave 250 amp welder, and machining capabilities to fabricate any jigs or fixtures needed. The completed weld will be required to carry the full current that the strip is rated at. We would appreciate any help regarding weld settings, gas, prep, etc. thanks bob
