This is a 3G Open Root plate TIG Welded all the way out using ER70S6 filler rod.
Here are the joint details as well as settings used for this joint:
3/16" thick carbon steel
35 degree bevels
Zero land, 1/8" gap
A TIG Finger bundle is a good savings
95-100 amps seems to be the sweet spot for the Root pass using laywire technique with 1/8" gap and 1/8" er70s6 filler rod
I used a #6 cup for the root pass at right around 98 amps reading out on the digital display.
For the hot pass, I increased amperage to 110
I switch to a #8 cup for the next fill pass and then finally a #10 for the cover pass
Walking the cup works best if you have an assortment of cup sizes.
A TIG cup kit is a convenient way to organize and to always have the right size cup when you need it without rummaging thru a tool box.
Our Weldmonger TIG pro kit has a cup for nearly any situation you might see.
We have kits for both 17 style torches and 9-20 style along with information on how to identify your torch on the product page.
Just select the kit for your tig torch you can be sure everything will fit.
