im runing 3/16 70+ in 3rd and 70. maybe try turning it down a hair and are you long arcing the bottom? I bet the pipe cupon is getting crazy hot on some std wall. but its better if you can put some pics up, its alot easier for us to help you out.

Najabat,
Don't stop at the very bottom, continue a bit past 6 o'clock on every run.
By overlapping each run on the bottom you will build up a bit more metal without having to try and stack it.
On the cap when you get to 6 o'clock go about 1" past then come back over that 1" then head back forward again to complete.
There is a real art to tieing in the bottoms so play around until you find what you are comfortable with.
Good luck,
Shane

the closer i got to making it look alright was that im pointing my rod towards the puddle then at the very bottom i go ahead and point the rod away frome the puddle in the direction im travaleing and start stepping it a little i use a short arc for everything except the hotpass i long arc I tack 5 coupons together to make four welds to try to keep it a little cooler what do you recomend long or short arc at bottom i will post some pictures this coming week thanks

as a general rule a tight arc will deposit more metal. Conversly, if I start getting a little too full, on a fill pass for example I start to long arc it.
Hope this helps.

I've been running past 6 o'clock as shane said. That way your not having to fill right there at the bottom. Seems to work well for me. Plus overlapping about an inch gives a good tie in.

i run my 300D in 3rd and on 55 when i cap with 5/32. but sometimes on the bottoms i will wait 30 seconds or so to finish out capping the bottom to let it cool down. if the pipe is too hot sometimes i cant get the bottom to stack up either.

That’s funny; I thought that I was the only guy that used Fein Saw blades to gap with. When I get them from the Fitters I grind off the teeth and pull some of the hardness out so they are less likely to break. Heat them up till they just start to show a very dull red then let them cool slowly this leaves them hard enough that they won’t stick in the gap after the tack up like a very thin wedge will and soft enough that you can wiggle the gee wiz out of them to get them out without breaking.

Here is a pic of 12 in. bellhole position weld i did with 3/16 70+ in the bevel and on the cap. My machine was set in third gear and 70 in the bevel then i cranked it up to 80 for the cap. The thing is we all have our comfort zones. All it takes is practise to learn where you like to set your machine. I run a SA 200 when i pipeline but i like my Classic II for fab work. It has AC for running power tools and such. But I know where I need to be on my settings because I know my machines. just my 2 cents.
