O/A cutting tip

[trackwelder]

I have an old oxweld,and a newer smith outfit.The oxweld is tougher than nails and has been abused by myself and previous owners.This is the one I let friends use when they stop by looking for a warm place to repair there snowplows.They know the smith is off limits to them I have been very pleased with the smith outfit and all the local shops have parts and accessories.

I've got a large Union Carbide/Linde/ESAB (each name is on at least one piece), and it holds it's own. Also got a oxy-weld full size cutting torch and another compact set with the MC cylinder. Regulators are all Smiths Hardhat. I can't tell a big difference, but **** I learned to braze using a cutting tip. I am a big fan of a rosebud tip though. About all I use is the rosebud tip and what ever tip in in the cutting atachment. For brazing, i like the smaller torch, or just use the cutting tip.

Smith has cool brazing tips that let you get in and out super fast.

i love victor, i have a set that was made back in the late 30's and it works better than the new set my freind just bought.

dont let ANYBODY tell you to use that HARRIS for a doorstop! what HORSESH!T ! i carry a 48" HARRIS "washtorch" and a 20" regular cutting torch [both model 62-3] on my truck and i`v had NOTHING but EXCELLENT service outta both of them! and i use them **** near EVERY DAY!lighter than a victor and more durable than a smith! i do love the smith mdl A cutting torch for comfort but they have a short lifespan out in the feild compared to a HARRIS CALORIFIC![and the tips are astronomicly priced compared to a harris tip] victors feel like holding a 3lb sledge to me[but they are quite durable and forgiving torchs]

I do own and like all three and I use Smith.... and I can't disagree with anything you have stated here.

I checked out that cool photo, and it prompted a question. I am not as experienced with my Victor Journeyman outift as I would like to be, just need to set aside a few afternoons and practice doing all kinds of stuff other than cutting with it. But, the caption in your photo said you were using 40 pounds of Acetylene to throw that flame. Is that psi? I thought we were limited to 15 for safety because of the instability of C2H2.

I agree Mack. I sure hope that was a "typo" And will be cleared up by Kllrjo.
Information like that is dangerous. Acetylene is dangerous when not desolved if the pressure is above 15 psi.
The pressure for Harris with the bigest tip on my chart, a 6S heavy heat is 70-90psi oxygen, and 10-15psi for acetylene.
Boys and girls you should never use acetylene above 15psi PERIOD!!!

[kllrjo]

know what? that was a typo [of sorts] the yard where i was doing this runs ACETAGEN, you haveta run a LP tip with this fuel.. they have the whole yard plumbed with manifolds for air/oxy/acetagen/water and the starting pressure on the acetagen is 40psi, manifolds are setup for gauges or straight hook-up [and you better have a **** good oxy/acet hose or youll have leaks everywhere, on straight hook-up!]

this is for "washburning ONLY!!!"

DONT EVEN THINK ABOUT TRYING THIS AT HOME!!!!!!!!!!!

as most of you guys know, you prolly couldnt get 40psi out of a acet regulator for ALL the reasons stated above! The only time i have seen these pressures run in a oxy/acet system is in shipyards, and for the aforementioned procedures ONLY!!!! get caught using a straight hook up for ANY other purpose and you will be DOWN THE ROAD![both literaly and figuritivly]
straight hook-up does NOT refer to hooking up your full oxy bottle to a torch hose sans reg!!! but, rather to hooking up to a regulated[albeit, high pressure] manifolded sys!my last oxy came with 2000lbs pressure, i ASSURE you that this is a MAJOR MISTAKE!!!

you guys do a great job in watching that NO misimformation is spread to the newbys and i appreciate that fact..and while nobody really chewed my butt for this, i`m kicking meself now for allowing it to happen[ never really had to worry about dangerous misimformation, or somebody acting upon that before]
again, i dont know WHAT the actual pressure at the manifold was,[although, i`m sure it was above NORMAL SAFE working pressures] just asked the yard employed helper what the pressure was for the photo captian...and yes, this torch has "flashback" arresters as do the straight hook up on the manifolds..[for that fact, so do the torches on my rig!]
the maritime repair industry is full of procedures that are considerd UNSAFE [and rightfully so!] but yet when used with DILIGENCE and by the right personel, can be used effectivly,,, ALTHOUGH the lost-time injury rate for the ship repair industry is ASTRONOMICAL!!!!!! [L5 laminectomy, myself]

i will endeavor to watch my postings MORE carefully from now on!

ps, i dropped 236 sq ft of hull plate in a total of 6.5 hrs while cleaning all welds off the chimes/skegs and keel, leaving all surfaces relativly clean for refit[after a quick brushing with the grinder to remove slag/rust]

[Fla Jim]

I'm just a dumb old mechanic. But I've never heard of "Acetagen" before.
Could one of you guys enlighten us more on this. I did a search and came up negative.
What is added to the Acetylene to keep it from dissassociating above 15 PSI?
Back when I retired from the Navy in the early 80's I worked at a Shipyard in Tampa for two days. I was working second shift on a LPgas tanker from the Islands, that was in drydock. The first night a guy was working on scuppers on the side of the hull. Another worker using a manlift managed to knock him off of the scaffold onto the dock. The Ambulance hauled him off. One of my coworkers said that happens frequently, no big thing.
The second night, while they were still purging the Big LP gas tank on the well deck with Nitrogen. We went down to the engineroom to remove the propeller stub shaft off the engine. I notice there was a signicant amount of diesel fuel in still in the bilge. we couldn't get the shaft loose with a portapower. The leadman came down with an extremely large rosebud torch (I don't know if he was using Acetagen) and proceed to heat the shaft coupling and also the diesel in the bilge, which if I remember was starting to smoke.
The third night I turned in my badge, tool tags and helmet and quit. At thirty eight I thought I was too old for that kind of life, I survived my South East Asia Adventure and didn't need to change that due to stupidity.

[kllrjo]

been there, seen that, jim!
dunno what yrd you were at, but if it was GULF TAMPA DRYDOCK then you were using ACETAGEN...its an LP gaseous form of ACETYLENE, came in a LP style tank, they used to make it right there in the port authority yard, right beside the "inclined ways"[huge concrete ramps, that they pulled ships up on for repair back in WW2] think its mainly used now in the phosphate industry as most yards have gone to straight LP[in the manifold sys, with ACETYLENE in bottles for critical burning]
when i worked the T5 tanker project for TAMPA SHIP during the mid 80`s we leased the old WESTINGHOUSE bldng and "prefit" sections of the ship in the bldng then disassembled,and barged the prefit sections to the main yard for final assembly...the westinghouse plant was on the gas lines that fed the area`s [natural gas?]homes for cooking/heating and such...TALK ABOUT A "COLD" FUEL! this stuff wouldnd hardly burn paint! and i was well used to LP as a burning fuel...ACETAGEN is more on the level of MAP gas, lots hotter than lp, but nothing like ACETYLENE!

scariest thing that ever happen`d to me in the yards?
burning into a fuel tank[that was listed in the ships "docking plan"as a "void" area...over a ton of diesel, luckily i burned in BELOW the liqiud level or i woudanae be here now!
BIGGASS FIRE[for a little while!]
or the time i "dawdled" going into a barge[that had just came in] and the pipe crew went first, and ALL PASSED OUT! fire rescue came and strapped on the 5 min. "bubble style" oxygen resperators, went down to retreive the stricken pipe crew, took too long and PASSED OUT TOO! apparently the last cargo had been something with a high degree of BENZINE and it would be absorbed through the skin and knock you out too! 1 firefighter died and 2 pipefitters never worked again....
craziest thing i ever saw anyone do WILLINGLY?????
watched a guy from texas put on an old style rubber diving suit and brass helmet and go down the ladder 40' into a tank full of UNLEADED GASOLINE to free a sump valve whos reach rod had broken so the tanker could offload that tank!
VERY IMPRESSIVE!
