Question for Jamlit

admin

Just happened to see you had the same machine i do, a Lincoln 225. My question is; I am going to try making my own turbo headers from mild 16 guage tubing. Any suggestion on where to start Amps wise? I tend to weld too hot. And also what size tungsten to use. 1/16 or 3/32 ? I am obviously new to welding.  Took some classes at community college, but would greatly appreciate any insight.Thanks,Dave

Reply:My paper Miller tig calculator lists 1/16" which is close to 16g, as 1/16" tungsten, 55-90 amps depending on the joint and 1/16" filler. Usually rule of thumb is 1 amp per 1/1000 of an inch, so  16g = .065 or 65 amps.http://www.millerwelds.com/resources...calculator.php..No government ever voluntarily reduces itself in size.

Reply:Hey sorry for the slow reply. Didn't see this until this morning.When doing 16 gauge sheet metal I use 1/16 gold ( lanthanated ). I set the amps for about 70 on the machine and use the pedal. I just start the arc small and keep pushing the pedal till the puddle forms and then keeps adjusting to keep the puddle how I want it. With then material preparation is one thing that pays off big time. Make sure you material is clean and the fit is as tight as you can get.  If you see the puddle starting to go, just pulse the pedal a little till it come back. Practice is going to be your biggest friend. I have only been doing small projects and not very many since getting the tig so I am no expert. After some good seat time I was able to get the results I wanted.Good luckMiller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.
