Good Price ?

admin

Seen the latest Keen Gas circular (not sure who has one near em)Tank prices seem pretty good thinking of upping my steel mig tank to a 60 cf (guess that is between a 2 and a 3) and then use my #2 cylinder (20 cf ??)  for pure argon to start playing with welding aluminum. always seems I run out of gas right after Tractor Supply closes lol http://www.keengas.com/catalog/sprin...ders-Carts.pdfHobart Handler 140Chinese Multi Machine
Reply:I wonder if you can get any trade in value for your 20 cf tank.  The small tanks seem just to expensive to fill versus a larger tank.  On my Ar 120 cf tank was going to be $36 to fill and a 40 cf was going to be $29 to fill, so I traded in the 40 cf and upgraded to a 160 cf tank.

Reply:I guess what I was trying to say is get two bigger tanks if you can because it will be cheaper for you in the long run.   The  20 cf tank is going to last an hour or so of arc time on aluminum which cost wise will add up.   May you should trade in the 20 cf and get two 60 cf tanks if you can.
Reply:I've got a 120 cu ft tank for argon and I use it up pretty fast.  And I'm just a hobby welder.  Last fill-up cost about $35.  I really don't think 20 cu ft of argon is going to suit anybodys needs, beginner or pro.  You might consider spending a few extra bucks and getting the bigger tank.  JayO is right, you'll save money in the long run not to mention the hassle of running back and forth to get gas.I've also got a 120 cu ft tank of co2/argon for my MIG and it has lasted a long time.Miller 211 w/ spool gunMiller Dynasty 200DXLongevity 60i IGBT plasmaO/A w/ crappy chinese torch/gaugesSouth Bend 10K latheGrizzly 4029 10x54 millGrizzly 7x12 hor bandsawangle grnders, bench grnder, bench belt sndr7.5 hp 80gal cmprsor
