Is it better to lease or buy welding gas???
I do however want to get welding!!! Also, most guys i spoke to said i would want 75% Argon and 25%CO2. I got a few quotes locally and the cheapest was: $240 To own a 50 cubic foot tank and $53 to refill it. $76/year To lease a 125 cubic foot tank and $75 to refill it. I just don't know exactly how much welding i will do.
pressure of full 125cf argon cylinder? - Miller Welding Discussion …
Since pressure varies by temperature, the real way to measure how full a bottle is, is by weight. According to Google: Argon: 1.78400 (g / l) = 0.111371482 pounds / (cu ft) So 120 cu ft should add 13.36 lbs. And then if you really care (roughly): pressure x volume = some_constant x temperature. The 'some_constant' depends on things like number ...
different regulator for different gasses? - Miller Welding …
Sep 23, 2008 · An "argon" regulator is completely approved and designed for all argon mixes. An argon/helium mix will probably be pretty inaccurate on the gauge, though. SOME people get away with using an adapter and running 100% CO2 through them. It …
Tri mix gas for stainless steel MIG welding.
Tweet. #1. Tri mix gas for stainless steel MIG welding. 03-21-2004, 09:57 AM. Hello all, For years I've been getting by doing repair welding on stainless exhaust systems using 308L wire and an 80/20 Argon CO2 mix. It does OK for repairs to stainless systems that have been in use for awhile and for installing new weld in catalytic converters.
Newbie welding gas buying question. - Miller Welding Discussion …
Gas is staggeringly expensive. Before we start to move to the discussion of least offensive cost, we need a big tank. A cubic foot of argon in a little tank costs a lot more than in a big tank. Where I live, no one sells a big tank, no one fills a big tank if you don't lease. For me, 4 -300 CF tanks a year it costs less to lease.
Unhappy with argon/helium mix - Miller Welding Discussion Forums
Tweet. #2. 02-25-2012, 06:23 AM. That is a common issue with a 50/50 mix. The argon has good cleaning and arc initiation and stability but with less thermal conductivity. The helium has poor cleaning and arc initiation and stability but has good thermal conductivity. You should only use the least amount of helium needed to produce the weld desired.
PraxAir proprietary gas question Stargon VS
Sep 26, 2009 · Ex: Take in 2 empty 300 sizes argon bottles and exchange for a 50# CO2 and a 200 bottle of argon. I only get charged for the gas because the lease is the same for all ''large'' cylinders. My point is, you should be able to try a bottle of the gas and if you don't like it then, when its empty, exchange it for a bottle of the gas you currently use.

Problems tigging with Maxstar 150s - Miller Welding Discussion …
Nov 23, 2007 · Problems tigging with Maxstar 150s. 11-23-2007, 08:25 PM. While tig welding with this machine I have found that the arc will just up and quit for no reason. It seams to get worse above 50 amps. I had someone watch the temp lite on the machine and that is not the problem. My supply power is 220v with a 40a breaker and I think that is ok.
