Hi,

I'm trying to either build or buy a resistance welder to weld a small copper rod (0.03" diameter x 1" long) to a piece of brass sheet. The weld would be at the end of the copper rod.

My research suggests that a capacitivedischarge welder would be what I need.

If anyone has any idea on what power range I should be looking for?

I have seen these battery tab welders on ebay but I'm not sure they would be what I need. - Updated Hand Held Spot Welder Welding Machine Laptop Mobilephone Battery 220V | eBay

Any suggestions appreciated! =) Thank you.
