Oxy-Mapp torch constantly loses puddle.

[Louie1961]

Made a quick cut on 1/4" plate with the new torch. Worked great.

Bit annoyed that victor made the propane regulator go to like 100psi when you use 4-8psi. Much harder to determine where 4-8 is on a scale to 100.

Curious how long the cones/primary flame should be expected to be? Granted the tip is recessed about 1/16 it only comes out around 3/16-1/4" total at best. Seems plenty hot regardless once it was set to a whistling configuration.

Watch the video I posted earlier in this thread from Victor (or Smiths?) They demo the "star" test for adjusting a propane flame. Setting up an oxy propane flame is very different from setting up an oxy acetylene flame.

I believe Victor torches already have a built in arrestor, adding another may lead to excessive restriction.

I believe that working with propane the risk are much less than with acetylene.

The torch with the Victor Medalist 250 he bought does not incorporate integral flashback arrestors.

You can see when one or both are incorporated into the handle. Nothing there.

There is a torch available with another Medalist 250 kit that incorporates check valves into the handle but they are only check valves and you would still need flashback arrestors if you wanted that protection.

Victor of course does have torches with both built in.

I added the quick disconnects and flashback arrestors at the torch end... it does add a bit of length but not to the point of being problematic. Stick with the name brand stuff and you should be alright. I ran into some cheap Chinese junk that had different hose ends for the hose and arrestors. Hose ended up in the trash in less than a year anyway. I do like my quick disconnects for using multiple torch heads though...

[BrooklynBravest]

I called victor they said the medalist 250 has arrestors built into the handle.

Not sure how, but that’s direct from Esab…

[smithdoor]

I think all Victor torches have arrested built in today. Some time late 1980's Victor was building into torches.

All my Victor torches do not have arrested built in. I purchased the torches new before the late 1980's.

Better to research it yourself. I didn't think it had check valves but it actually does.

It does not have flame arrestors. You can't CALL anywhere anymore and get accurate information.

Did you tell them you had a Oxy-Propane Medalist 250 kit with a WH411C torch handle. It has only check valves but it does not have flame arrestors. They are not the same thing.

Only this Victor Oxy-Propane Medalist 250 kit has handle that has flashback protectors.

https://store.cyberweld.com/victor-m...0384-2544.html

This is decent medium handle with them built in. Cost almost what the kit cost though.

The info you're stating is what I found.

I'll have to get some I guess. Kind of silly to sell a torch without them if its considered a critical safety feature.

[smithdoor]

This torch was purchased around 1980 and was used everyday to 2004.
Still in good shape today.
Victor will last a life time.

Yes sir you would think.

We used the oxy-acetylene for 100 years without check valves or flashback protectors though. I guess if you try hard enough you could mess up.

Learn the rules and follow them and pretty hard to have a issue.

[Welder Dave]

Not a big deal to add flashback arrestors. Some safety police require them on the torch and the regulators. Are they critical, not if you observe the proper safety protocols. Otherwise every torch sold would require them. Are they a good idea, definitely! If you're running propane there is way less chance of having a flashback. I still shake my head about when a guy came into the welding supply and wanted to get quick couplers for his O/A hoses so he could hook them together when he took the torch off. He said they're different and was thinking of using air hose couplers because they are the same. He would have had to cut the hose ends off and use barbed air fittings because fuel gas is left hand thread and the threads are a special size (B). I'm kind of glad he talked to me first before he just went and did this. He may not have ever had a chance to talk to anyone after the explosion. A branch manager was mad at me and even complained to my boss because I wouldn't give him a part number for a high flow acetylene regulator. His customer was using a large rosebud and wasn't getting enough acetylene. I asked what rosebud and what size of cylinder or if he had 2 cylinders manifolded together, etc. Couldn't in good conscience give him any part numbers or what he wanted. I'm not telling him how to make a bomb! Likely the regulator his customer was using got blocked by acetone coming out of the cylinder due to too high of withdrawal. It may have saved the guy/idiot's life. My boss thought I over reacted until I found an article online explaining exactly what I said. It even mentioned someone going into a welding supply and talking to someone unfamiliar with how dangerous it is. My boss had a change of heart after reading the article.

To your point of proper, i was always told you crack the fuel gas, ignite it and then add o2.

To my surprise victors video on propane says lightning both together and adjusting is acceptable. I really only have done that on a windy day as a last resort.

[Welder Dave]

Propane is harder to light than acetylene and by adding O2 the flame won't go out right after it's lit. It's perfectly safe.

But with acetylene, should they be a no-no?


Side note, anyone know if these are loctited on? The double male nipple for the connections. It’s driving me nuts that they aren’t at the same height, and i can’t budge it. Don’t want to add head and ruin something…

It’s petty, but with the quick connects on the stems look wrong.

i think it is deliberate.

being so close together it would be hard to slide the quick couplers back to disengage if they are both the same length.

They’re off by maybe 1/8” at best, i think it’s a quality control error honestly. They have plenty of space to slide the collars.

my misaligned couplers would drive you around the bend LOL

[whtbaron]

My handle is the WH-411C and they do appear to be even, but it is older. What you really need is a yard full of eff'd up farm equipment to take your mind off things...

[BrooklynBravest]

Thats a nifty holder. What's it for? Forging work?

I kind of regret not buying the western matching brass color disconnects they were $14 more though with equal reviews.


I tried heating the nipple lightly (which is also the check valve) and couldn’t budge it still.

[Lis2323]

.

yes and acting as a third hand in general for heating things up.

i don't use it nearly as much as i thought i would which just reinforces the sad fact that i'm nowhere near as smart as i think i am.

What would you do to fix them though ? They are different length pieces and both are already bottomed out. They may be pressed in or could have a hardening sealer..

You will be even more upset if you mark up your new torch or break one off trying to correct it. I agree that that sucks man. Bummer for sure.

Some torches advertise that inlets are replaceable. Thinking these may be are the ones that are not that way.

Look down through them you should be able to see if threaded in if threads exist up in beyond the fitting.

[BrooklynBravest]

They're definitely replaceable as they are the check valves.

I'm gonna call victor tomorrow and ask.

I don't think theyre bottomed out, the fuel one is screwed in further. Hard to see in the pic, you can see the rim with your eye looking at it in person.

[whtbaron]

I think it was just a change of fitting suppliers or styles in the assembly line... 2 totally different styles... They were very accommodating with warranty issues when I talked to them, but is that really worth sending the handle back over?

[danielplace]

I do see it plain as day now. The long one isn't threaded to the shoulder like the short one.

All thread lock types are removed with heat. But does it require more heat than the check valve can handle.

You want to remove and reinstall the same one that may be a issue. Maybe a heat gun could soften it with a more controlled heat and get it out so you can try to get it in further the next go round or see why it didn't go in all the way to begin with.

Typical of Chinese products to have irregularities. Does the manual show the check valves have parts numbers and are replaceable?

I doubt they have anyone anymore that is repairing these at Vitcor/Esab to know anything about how they come apart. Warrantees are probably just replaced.

Then again take a look at this Victor design. Almost ensures to get valve orientation correct almost no way the lengths would end up the same. I don't think even length fittings concerns them.

Damaging the check valve was my concern.

Oddly enough i have a second kit coming tomorrow because Amazon is ridiculous,

The price dropped $40 immediately after I bought it, so I called them to adjust it and they said the only way is to buy it again and return one. Which seems wild to me but I guess it somehow works for them,

Anyway, I’ll see if that one is the same.
