How to Weld in Tight Places
Kevin is working on a new sculpture, Tiny Tess. He's tacked together the many parts of the sculpture, but now he needs to weld all the joints, some of which are inside this small sculpture. His standard TIG torch is just not going to fit.
He shows how you can get into some of the joints, but reaching where you need to get to is awkward at best.
Kevin can change the welding torch back cap to a medium or small size version (although that means a smaller tungsten, too), but he still has the cap to try to fit into small places.
Another option is a smaller cup, such as a stubby gas lens.
Or you can use a small torch. Kevin bought a tiny torch - perfect for his sculpture Tiny Tess - from CK Torches through TIGDepot.net. The micro torch is as small as a WaterPik.
This mini welding torch has three different heads: a straight head, a 90 degree head, and a 45 degree head. It comes with clear glass Pyrex cups, which allow you to look through the cup to see what you are doing. It also comes with the smallest alumina (pink) cup Kevin has ever seen.
The alumina cups are more shock resistant - the clear Pyrex cups will break more easily.
Next Kevin puts on his welding safety gear and fires up his Everlast POWERTIG255EXT at about 105 amps. He's using the foot pedal, which allows him to control the amperage up to 105. The flowmeter is set to 150 CFH.
After running a small bead, Kevin says that the small torch will make his job a lot easier, as he'll be able to get inside a joint and work all the way around a joint without having to try to get the full-size head inside the sculpture.
Now he's ready to play!
