In 06 the electric company replaced the transformers on the poles outside our shop (after the L-tecs fried), I am thinking that caused it as they both fried the center transformer. They had a pure, clean arc that is hard to beat. My sales rep from the gas company we work with got back with me today and he sharpened his pencil. The HP oxy is $.04 per CF (no dem.) and the liquid oxy is $.0125 per CF + $1 per day tank rent. Basically a 300cf is $12 and a 180ltr (4500cf) liquid is $56. There are other factors to consider: much fewer reg changes, ! delivery charge and fewer bottles to shuffle. However the liquid is heavy! And has a tendency to vent. I'll post an update if I give it a try. I have managed to work it out so that I have a complete weekend to work on our table! Steel is in and cut, drawings are done. Now to fit and weld. Everyone have a great weekend!

I've never tried the liquid myself. I'm sure it's a good deal if you cut heavy material most every day & run your machine at least 5 days per week.

One of my customers that does run a machine torch sometimes 2. 8 per day & 5 days/week tried it. They switched back to compressed cylinders. I don't know what the specifics were but it had mainly to do with the daily rent including weekends holidays etc. + the fact it vented on the off shifts, weekends & holidays. I'm sure they didn't change back on a whim either. I'm sure they ran an actual cost analysis over a period of 3 months or so. They really run a streamlined 1 shift per day manufacturing facility. They really don't use much of anything less than 3/8" thick. & literally semi loads of 8' X 20' sheets of 1/2, 5/8, 3/4,1, 1 1/2" plate.

The only welding machine I have used that I like better than the Lindes is the old Hobarts. The 15 or 20 HP electric motor driven DC welders. I still have a 300A CV (MIG) machine in working order. I just don't like the wire feeder as well as the Linde MIG 35s. That old Hobart will not self thread wire at all. You have to remove the upper drive rollers & thread it then re-install the rollers. Not a big deal but just something else to aggravate you when you run out of wire 15 min from being finished with a job.

Could I trouble you for the ASCO part number. My local ASCO supplier just handed me their big books of ASCO when I asked then for valves. After some pressure they contracted the main supplier who then asked for operating pressures etc. It's a bit frustrating as everytime I visit them they have a new question.

Thought I could reach the destination a lot quicker if I new what the destination was. My current table is an all steel construction and I'd like to use it to cut the parts for my next table which will be dedicated to cutting steel plate. Then I'll dedicate the current one for the wood shop.

Thanks in advance for the help

Here is the part #,
8262G202N
It is 110vac, you will need the proper voltage solenoid for your country, but this will get you real close.

Good luck,

Thanks a million. It appears they can do 24V DC. I'm keen on using two 12V Batteries like the ones in UPS and Home Security systems. My efforts for now have secured me a conventional cutting torch and thats no fun to use when you want to cut a whole plate.

I'm using the V23 BobCad software and and very impressed as it allows you to tailor your machine to your needs quite well. I've had a few heart ache moments that were more related to my ignorance than the software. But it was during the correction of a heartache moment that I found the Mill Setup program and then discovered what looked like an unending source of possibilities. One being to switch gas on/off etc. The next thing I knew, I was converting my Router to a Gas Cutter. It's been fun so far.

Thanks again
