I'll be getting all the accessories together by this weekend to start Tigging. I'll practice before the real job, but the job is non critical, so most of the practice will be the job. The basic weld will be a T of 2" square 1/8" wall extruded aluminum. I'm assuming 6061, you can disagree, I'll fold like paper. It will be like a fence rail. A top and bottom with with pickets welded in between the top and bottom. I don't mind a little build up, but I am going to lay this down and install five quarter decking on top. I'll weld all the way around, meaning a butt weld and an inside corner weld. I could easily chamfer the butt weld on one the picket, both pieces would be possible but more difficult.
Is it reasonable to chamfer only one side of a butt weld?
Should I tack it all complete, then go back and finish?
Any better sequence to follow? I would like it flat.
What fill rod material and size is recommended?
What size tungsten?
Should a have a point or ball it?
This is the arraignment of 2" square tube. =========================================== H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H ===========================================
I'll be using my just purchased Everlast 200DX.
I can adjust frequency from 20 to 250 hz
What frequency is a good starting point?
Cleaning balance 30% to 70%, I'm seeing around 60 to 65%
Is that a good starting point?
Do I want to use pulse?
I'm seeing 15 cfh for gas, I'll need to convert that to Liters per Minute.
Is 15 good?
Here's front panel video, start at 5:00 to see the adjustments.
Thanks, Mikek
