========[ Invite a Friend - http://www.ganoksin.com/invite.htm ]======== > Kevin indicated he was using a WP50 and occasionally a WP9 torch. Don, It's the other way around. I don't know that it makes a difference other than the shape of the torches are different. The WP-9 has a larger tungsten and amperage capacity. I have a flex coil in the handle which allows me to blend it in compound shapes and I use a gas lens cap. I have a long back cap on it so I can put full length pieces of tungsten in it. The WP-50 does not have a back cap. Currently is unavailable with a flex coil and can not be fitted with a gas lens. The large amperage weld was made with as a short duration (dwell) as my machine is capable of: 1/10 of a second. http:// tinyurl.com/6pqtr3 These welds were over 2 mm in diameter. Conductivity and area influence the amount of amperage. Consider that it is very difficult for me to join a fiction post to 10 X 10 earring plate. The post wants to melt away from the plate. After a tiny connection between the post and plate is made the post then can have a base fillet added with greater ease. I believe this is because the post becomes part of the total 10 X 10 area in which electrons are energized. I encourage you to try some welds. Find a machine that can do spot welds as well as continuous runs of welds. See what happens and let me know.
