Acetylene torch kit wanted in Manitoba


Anyone in the Winnipeg have a cutting torch kit for sale, or maybe know of one?

I am thinking it's time I got one. I've done without all these years but it seems like it would be nice to have one instead of having to get someone to come over or take my stuff somewhere to get worked on. An old used one is fine as long as it still works.

Haha, no, I actually did that neatly because there was no way I was going to run a torch inside my car!

I need it for some little things and I'm getting tired of having to find alternatives when I need one.

The cylinders are whats going to cost. If you don't plan on ox/acet welding just go with propane. About $18 for a propane tip and I'm sure you have a BBQ tank to steel when you need the torches. Customer owned o2 cylinder is about $220 for a 55cu ft, should be able to buy from local welding supplier.

I'm just going to go with those little cylinders that need no contract. I know they don't hold much but I don't need it much.

Are you saying the propane tip works for heating up seized nuts etc? I don't need a cutting torch, I just need to be able to heat for bending stuff, or for removing rusted bolts and nuts. If propane works, I'll buy a tip and just do that. I didn't think there was something that worked with propane to do that.

i have old cylinders here of straight Mapp gas,a plumber told me to use it ,hotter than propane.i see the new ones are mapp/propane combined, the mapp gets things red hot for me.

Carl Here is the deal Acetylene = hottest and flame shields oxygen so you can weld Or you can braze as well Mapp = almost as hot as acetylene should not weld with as there is no shielding for the atmosphere Propane = great for heat bending and seized nuts and great for brazing DO NOT weld Down falls uses more oxygen and a little slower to heat the patent metal. I am just a hobbyist. This is what I have learned hope it helps Xoxo

I am going to check into the propane tip because by the sounds of it that is all I need. What about a hose? How does the propane tip connect?

 Are you looking for a 0xy/acet-propane setup or an air/acet- propane setup? If oxy/acet just change the tip in the cutting head to a 2 piece propane and your set.  T grade hose for propane. Also try to buy a common brand like purox,smith,harris,victor, LA(liquid air)etc. Tips and torch parts readily available .

The acetylene nozzle has a flat front-face and no flame holding skirt. The flame velocity of acetylene is much higher than that of the other fuels and just the interaction between the flames of adjacent properly-placed preheat ports is sufficient to hold the flame on the face of the nozzle at the flow rates/velocities used in cutting. Note that the skirt of #3 is shorter than that of #2 indicating that the flame velocity of propylene is higher than that of NG/Propane so therefore the shorter skirt is sufficient for propylene. The flame holding for the NG/propane and propylene tips come from the proximity of the adjacent flame ports, the interaction of these adjacent ports, as well as interaction of the flames with the skirt wall.

I was curious so I looked it up...

1) is an acetylene nozzle,
2) is a propane/natural gas nozzle,
3) is a propylene nozzle, and
4) again is a propane/natural gas nozzle of one piece design.
http://www.esabna.com/us/en/education/blog/oxy-fuel-torch-tip-nozzle-preheat-design.cfm

According to several websites (always the most reliable source for safety related information ... use at your own risk), you can get away with the same regulator.  They make a regulator designed for propane, but it seems many people just use the one for acetylene.  The T-grade hose is apparently the same for propane and acetylene.  So the only change most people make is the actual cutting tip - as Hawkeye shows above.

Apparently propane is fine for heating, cutting, brazing and silver solder.  But not for welding - near as I can determine, the propane flame must contain some oxygen that contaminates the weld?  You'll use a lot more oxygen than you would with acetylene, but oxygen is cheap compared to the price of the acetylene.  The higher oxygen consumption would suggest you'd want as big an oxygen cylinder as you can get... 

Regardless of which gas you choose, the bigger your cylinder, the cheaper it will be if you use a lot of gas.  Cost of filling a cylinder includes a filling fee, and a charge for the actual gas.  I back calculated the costs from KMS price list, and their price seems to be:

For Argon-CO2:

$30 filling fee, and the gas (C25 Argon-CO2) is $0.32 per cu. ft.

For oxygen:

About $18 per fill, plus $0.14 per cu. ft.

For Acetylene:

About $35 per fill, plus $0.46 per cu. ft.

 

For the back yard user, the smaller tank might still make sense.  Larger tanks cost more to re-test.  So if you only use one tank every 5 years, you'd be re-testing after every second fill. 

The propane has the advantage because you probably have at least one propane bottle already, and you can use it for the BBQ when you-re not cutting off an old exhaust system.  

I think I'll look into getting some propane tips.

 

Sorry for the long post.  I got carried away.
