I recently bought a Hobart Handler 140 while on sale @ Graingers. Been too
busy to take it out of the box yet.
What size cyl would be the best for a newbie Hobbyist...how long roughly
will a tank last ?
I see there are 20 cuft and 80's. Will a 20 run out often ?
Like many things, is there a savings in getting the BIG one instead ?
Howdy Howdy! I would certainly recomend purchasing the 80 CU ft
cylinder for your welder size. Mine has lasted several years between
fillings. Refill here is about 20$ for C-25 gas. The tanks price
difference aren't that different, and I think it's a much more common
size anyway. Hence, volume of tanks make it more cost effective to
produce type of thing. (good all around gas for the process and
materials our lil wire feeders handle) It's 75% argon, 25% CO2. For
me, I am upgrading to a 150 cu ft tank, but thats because I'll be
getting a Power Mig 350 MP which puts out 300 amps at 60% duty cycle.
It also consumes about twice the gas. I found for a 150 cu foot
(overkill for the lil welders) it's only about 25$ more then an 80 cu
foot cyl, and 10$ more to fill. Also, for referrence, once you get
past 250 amps, the processess change a little to a spray transfer and
not globular or short circuit transfer so the gas changes to facilitate
this too. I'll be using 100% argon for arc characteristics now. Happy
welding! Brian Lee Sparkeee24
I went with an 80 cu ft tank, and I'm a hobbyist. You can do the math
and calculate how long a tank of a given size will last between
refills. With your regulator set to 20 cu ft per hour an 80 cu ft
tank will last you 4 hours. That's 4 hours of actual welding, of course.
For me, the lion's share of time in a welding session is spent prepping
and fitting metal before welding the joints. I'd say on a rough guess
only 25 percent of the time is actual welding time per session, so
an 80 cu ft tank will last me for 16 hours total. I only spend about
4 hours per session on Saturdays, maximum, so an 80 cu ft tank should
last me at least a month between refills. So far this has born itself
The other nice thing about an 80 cu ft tank is that it is not too big
to be carried around. I bring my tank to the welding supply store
to get it refilled, which requires me to carry it to my pick-up truck
and then into the store, and then back again. Although I have no
experience with larger tanks, I suspect that a bigger one would start
to get unmanageable.
(BTW, I made a wooden cradle that fits in my truck bed to transport my
C-25 tank. Made of 2x4's, the tank rests horizontally between two rails
and is strapped down to them. It's very secure and convenient. Not for use
As a little thing I do with my Dynasty with an 80cf I have a "hockey players
bag" I can fit two 80 cf cylinders, grinders, backing and purging gear,
cables, consumables,filler, etc. It's a bit heavy but I can always drop a
cylinder to cut the weight in half. Makes lugging all the stuff way easier
when a cart would just get in the way. It fits in the trunk of a car, looks
innocuous enough not to be stolen from the inside rear of an extended bed
pickup. all hidden, and yes, I cap it off! It was 20 bucks at Sports
Fraser Competition Engines
What are you welding? For steel fabrication, some percentage of CO2 will aid
penetration. 92/8 supports spray transfer and should be more appropriate
than 100% argon for most steel applications. You'll get into spray at a
lower amperage with 100% argon but is it worth the trade-off of lower heat
Howdy! as to the 20$ refill, it may be because I am browsing heavily
at a new welder, he wants me to get at HIS shope :P I try and get all
the accesories before the welder. That way all the welding shops give
you good deals cause they want you to spend the 4 grand at their place.
And then you get it at the place that treated you the best. Brian Lee
