I know you can use acet tips for propane, how about the other way around? Won't work, lousy to work with, unsafe? And what are the 2 or three TEN tips most commonly used for lugs and fillets? I know its been posted before but I dont want to battle the "search engine" endessly if someone can give me a quick answer

thanks,

Brian

I've never seen anyone talk about that. I am not sure we have had a thread about propane/oxy torches here. I would be perfectly happy with a Smith AW205/Victor 1/Harris 3 as my only acetylene tip, so I guess I wouldn't mess with the screw on tips

Brian - This topic has seen a lot of postings over on Velocpede Solon in their framebuilders section. Doug Fattic has talked a lot on this. Andy.

I'd read the link on Velo before, read it again(which I didn't mind in the least) but didnt find anything about using the TEN tips with acet. Anyone have a specific location for it? I have some on order so I was wondering, I'll give them a try when I revceive 'em.

I haven't used acet on the TEN tips. The recess on those is because the propane flame burns a bit further from the tip; the recess prevents blow outs. IF acet burns closer, then there might be a risk of overheating the tip?

One of the problems in using a TEN tip to practice with acetylene is that it is probably the wrong orifice size. A Victor #0 or #1 tip is what I would be using to practice with oxyacetylene and a TEN-2 or TEN-3 to practice with propane. It would be one hot flame using a TEN-2 tip with acetylene that would require faster reaction time to keep the joint within the proper temperature window. When one is learning how to braze they have difficulty reading the heat indicators and then adjusting the flame fast enough. For learning purposes, it is better to start with a smaller flame so things heat up more slowly and it is easier to understand the heat stages the joint is going through.

To specifically answer your 1st question I do not know if a TEN tip works with acetylene. I wouldn't use that combination myself as I have all the right equipment. My suggestion - if you already have the UN-J mixer/elbow - is to get the TE acetylene tips (not to be confused with the TEN propane tips) designed to work with a UN-J mixer in a #0 size to start out with.

To answer your other question is that a TEN-3 tip is the one I most commonly use with propane (compared to a #1 with acetylene). I can use that tip for almost everything. For big stuff like fork crowns to steerers, I use a #4 and little things like braze-ons I'd use a #2 (if I am ambitious enough to change the tip).

Thanks for the info Doug. I have a Victor 100c torch and acet tips for it but this is my first venture into propane and smaller torch handles, therefore the questions. While not too heavy the 100 series handles balance is poor, holding it at the bottom mounted control valves balances it but its pretty lousy to work with it from that position. When holding the middle of the handle you're fighting the bottom valves weight and the hose weight. I know I'm not telling most of you anything new, just putting it out there as general info.

I mentioned above I got the Uniweld 71 and also ordered a Victor UN-J, TEN 2,3, 4 tips and a light weight hose(hose is the $45 one from TM Technologies). I got a bonus of sorts from work, couldn't think of anything I'd rather have than the propane set up, really looking forward to trying it out. I'll use my acet regulator for the bbq propane bottle but will stick with the oxy reg and bottle for awhile to see if I want to get an oxy concentrator.

the problem with using a j28 for me is that the tips are so expensive. But you do see the tips occasionally on ebay. Granted, there are a lot of clones so finding every one is tricky. Like I said in one of my previous posts, once you get reasonably good, you only need one tip for most work, two will definitely do it. Sometimes I'm working and think I should change to a smaller tip, but it's not something I would do if the torch was already lit

calstar 

Yes they are. I decided to also get some, Victor TE series or clone. I've found this place with some knockffs for about 1/3 the cost https://www.atlweldingsupply.com/Tip-Ends_c_229.html anyone buy from them? Or if you have an alternative to whats here(used is good) excepting the Gentec please let me know.

Thanks, Brian

when I was looking on ebay, this chart was very helpful. I ended up with a pretty complete set of victor/harris/turbotorch tips for just a little more than the cost of one tip. Wasted some time doing it, no doubt

I have some Gentec TEN tips and like Doug (in the Vsalon thread) I found they aren't as nice as the Victor ones. Totally usable but you get what you pay for. I'm tempted to buy some TE tips (they are cheaper) and drill the recess myself.

calstar 

This is least expensive place I found for the TEN tips, $23. https://www.buyweld.com/ten.html I cannot find the TE tips(they seem to be less common than the TENs) for cheaper than about $32, if there is a source for the TEs for a better price I'd like to know.

thanks, Briain
