    Default spot welder copper pipe electrode?

    I saw some discussion on this on another thread. It looked to be a piece of copper pipe with a union on one end and then it was flattened out so the tip could be mounted. Has anyone used one of these on thier spot welder?? If so what was the out come. I am going to be needing a modified tong in the near future and just wondered if this would work. Here is the thread with a picture of the electrode. purple power on yugo wood - pic

    Am I correct in how to make the electrode? Is the pipe just flattened out on the end and tapped for the tip?

    yes I did just flatten out the end of the pipe drilled a hole tapped it for 10-32 and screwed in a MIG welder copper tip. I bought a whole box of tips for just a few $ at HF.

    That's what I did. I cut about 3/8" off the tip so it would fit in the receiver. Also shaped the tip to a flattened point about the same size as the spot welds on a Saiga receiver. I soldered the tip on but the solder melts after about 2 welds if I don't let it cool off.

    I made one of the electrodes up today. I works great!! The best part is, it is cheap to make! I used a mig welder tip on the end as Steelcore suggested. The electrode cools off pretty quick as well. Anyone that is looking for a cheap modified tong should consider this!

    The copper tubing mod does work. The mig welder tips are available at Sears and other common hardware stores. As others have suggested it is a simple matter to reshape the tip to a desired point. At times you may need to retighten the nut that secures the tip to the pipe.

    If you will bend the copper tube around the sides of the nut it will help it from loosening up.
