Mig gas Bottle Questions

Off the top of my head I can't think of any dual shield wires that don't run on DCEP. But I can think of at least three flux core self shielded wires that run on DCEP. Most of us weekend warriors won't be running any of them. ;)

Definitly brought up a good point Scooby..I may cut my loss's on this wire and just get a spool of regular soild core with mig mix gas..Either way i will keep the info on lease big tanks and owned smaller ones at hand when i call praxair..

Sheilded arc. welder is cv-300 with an ln-7 feeder with the serrated rollers. Wire size is .045. I am not in a high production welding enivorment( altho i can lay some serious weight when required with this welder). I mostly just build trailers, splitters, fix stuff and general fabrication but recently have needed to have cleaner welds for cosmetic reasons..

For general fab work you'd be hard pressed to find a better process than short circuit Mig welding with .035 wire. You can set your machine where it is just a tad cold for flat welding, and never change a thing and go right into vertical up welding. You should be able to build most projects without ever adjusting your machine! ;)

Bite the bullet and leased a 150 cf tank for 70 bucks a year. Same price to fill a 150cf tank as it was a 50cf tank. ( think that was mention somewhere already here too..)The only tank i could buy at praxair was a 50cf and it looked pretty small.. Had a 44 pound spool of soild core wire in hand when i mention to the clerk that i had a ton of outersheild 71m and he said that was better than what he was gonna sell me when used with gas.. So i am gonna use it with about 50cfh of gas and see what happens..

The tanks look small... cause they are :thumbsup::laughing:

Since your running Outershield i think you made the right decision. If you find your not using that much gas, buy a tank next year.

Oh I see it now, said the blind man.:D
I always liked dual shield, to me you have the best of both worlds. I was the supervisor on this project. I elected to go with dual shield to weld the 10-feet dia, 1-inch wall pipe hanging on the hook of the crane. 100% xray, I forget how many splices the guys had to make on that project.
