You do have 2 tanks to place somewhere close to where you sloder. I use tanks that are larger than what you see GL offer. They are about 36" tall, maybe a little less. Means you need to refill less. I refill less than twice a year. The tanks I have last close enough to a year it seems like I fill them only 1 time a year, for less than $40.00!!!
You have to "buy in" to the tanks generally. That means, you own that tank, and when it's empty, you take it to the welding supply and trade it for a full one.
The cost for a refill last time for me was less than $20.00 for Acetylene, and less than $18.00 for Oxygen. My cost for 5 oz. of flux is $5.00. The cost for silver solder (on 4/11/08) was $79.85 for 1 troy oz.
After I purchased my first 2 tanks ( 1 oxy,1 acet.) I found it worth while to buy a 2nd set of tanks and always have a full set on hand. That way you don't have to jump up to go get gasses at a busy moment.
Cade..listen up dude.....with these costs, and yours in Texas being close I'm sure, what are you waiting for???
The flame is smaller, hotter, and more manageable than butane. Not to mention a whole lot less expensive. "Buy in" is the main cost. You will regain your output quickly in the expense area, and the time you will save using this smaller hotter flame will put more of your income into your pocket and less into buying butane and soldering at a snails pace costing you time....lots of time.
Like I said before, if you for some reason don't like it, these set ups are easy to sell in the newspaper.
Also, you try it and dont' like it, I'll buy the torch from you for exactly what you paid for it.
Time to run Cade,
Mike.
edit: true water to run a H2O torch is cheap, but the cost to purchase one is about 3 times that of Oxy Acet. Up keep and repair can also be higher for an H2O torch.
