Rated 2.9 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by you would be surprised I bought this torch with my FIRST robotics team in mind thinking it would be fun to try some welds on this years robot and see if it worked. To put it in short, from my preliminary test i will mention, this torch dose a lot more than i thought it would be capable of. I have never welded before but i was able to figure out how to use it in a timely manner. In my tests i was able to weld regular steel nails together with no difficulty using only the brazing rods that came with the kit and i'm still trying to break the weld by bending and smashing it on the ground. My bend test only succeeded in bending the nails leaving the welds untouched. I was also able to cut fairly easily through the nails and ended with a clean cut. So after working with steel i decided to root around in our scrap metal bin in our robotics shed and get some useless aluminium. I was able to get a good weld on it with a lower burn and cutting the aluminum was a lot more fun than it should have been but hey i was experimenting. I finally ran out of the oxygen after an hour to hour and a half of continuous use and i think it would have lasted longer if i was more conscious of weather or not the oxygen is actually off or not, and that is really my only complaint is that the system of regulating the gases is a little haphazard but it you adjust slowly and in equal increments its only a minor nuisance. So if your a person looking for a slot of power in a small package, or a total welding newb like myself whose interested in getting into the craft this is a fantastic way to start. December 12, 2013
Rated 2.0 out of 5.0 by not the best this torch set is good for lite projects and maybe heating up a bolt or two but I found it a pain in the butt to use the oxy cylinders don't last long and the control knobs are touchy ive been a welder for years but wont recommend this for anything but a small project also if you braze metal use a respirator the fumes from the flux on the rods are not good to breathe for your health..

Rated 4.0 out of 5.0 by It worked for me It worked wonderfully for me. i have been using mapp gas to do some hvac brazing on copper but it always took a frustratingly long time to get the joint heated enough. I know most people use a b tank but its too big for my uses. this worked perfectly and fittings were hot enough to braze in less than a minute . its as good as using a b tank. i will admit the oxygen adjustment is a little troublesome but the key is to make about 2 or 3 complete turns of the dial then slow down until the oxygen comes in . if the flame goes out while adding oxygen then dial back one turn only on the oxygen then relight and begin to turn the oxygen again slowly, do not turn the oxygen all the way off to start over, its much easier to do it that way.

Rated 5.0 out of 5.0 by works just fine i have had no problems with this unit. it works well for soldering large copper like the three inch i bought this to do. you have to turn the oxygen on slowly like ridiculously slowly. it will work and it works well. April 19, 2015
Rated 4.0 out of 5.0 by Good for what it is, don't expect the unreasonable for 60 bucks Keep in mind, this is not a professional welding outfit (regardless of what Worthington's online video states). It is meant only for LIGHT home use and for short projects (10-15min working time). If you want to weld, cut, or braze any average project, you NEED to buy a professional setup. If you are working on a tiny project, and are thinking "I need something much hotter that Map/Pro or Propane alone, but don't want to speed hundreds on a professional setup" then this is PERFECT. It gets the job done so that you don't have to send out your repair to a shop. Also, this is PERFECT for DIY guys. The short burn time is NOT a knock against the torch, its CHEMISTRY. Why do you think you need to refill a 300 cu ft tank of oxygen several times, while refilling your 20 lb propane tank once in a oxy-propane professional setup? Realistic knock on the Expect to spend at least the first 10-20% of burn time trying to figure out how to light the torch. After you get the hang of it, it is pretty easy. And it is very cool to be able to have a torch capable of welding and cutting (sheet) metal with only 60 bucks investment. The major problem is the oxygen regulator design, it is sharp and sensitive. From an engineers point of view, this is probably for your safety. According to their documentation, the torch tip has a flame arrestor, but to increase safety, they probably want you to be able to shut off the oxygen tank completely and quickly in case of a flame out. It takes almost 2.5 full turns of the regulator until the oxygen starts to flow. Open the fuel and light so that the flame is ~1/2 inch from the tip. Then turn the oxygen regulator on 2 full turns, then VERY SLOWLY open is more. Bring the flame down to the tip by adjusting the fuel (map/pro or propane). Then add more oxygen, then more fuel, etc, until you get it to how you want it. I cannot stress enough SLOW valve movements. The torch is not well designed and quick gas changes induce resonant waves in the torch that make your flame dance from reducing to neutral like a strobe light. I cannot speak to it's durability, as I have only owned it for a few days. But the cylinder threads and regulators are cheap, so do not HE-MAN the tanks on the fittings. Last, keep the tip clean. It helps more often than you think. And if you like it, buy an oxy-acetylene or oxy-propane professional outfit, welding is fun! January 16, 2014
Rated 1.0 out of 5.0 by not worth it I've been using a propane torch to bend and form 1/8th" round stock for decorative wall hangings, and wanted more heat to be able to heat longer sections, this torch worked great, for 30 minutes, and then i had an empty oxygen tank. Replacing a $10 oxygen tank after a half hour versus replacing a $3 propane tank that after HOURS of use is still running strong is not cost effective at all! Returning this tomorrow and i just bought it tonight! I'll just have to work with propane even though it takes longer, because the O2 regulation is terrible with this set and i would spend at least 10x as much money just replacing O2 tanks!

Rated 1.0 out of 5.0 by Almost completely worthless The cylinders while coming from an unopened package were light as if they were not properly filled. The adjustment valves could not adjust the flame well enough to keep the torch lit so that I could braze. I am ashamed to see that the product claims to be made in America. Such terrible quality. I will be returning my purchase to the store for a refund. July 24, 2014
Rated 4.0 out of 5.0 by Great for small jobs Bought this torch to make small repairs on my garden tractor which require some bends to the steering linkage. I am experienced at welding and cutting and know how to quickly adjust the flame. If this is your first time with this type of equipment, you might find it difficult but a good mechanic should not have a problem. For larger jobs, get a bigger system.. but for an occasional home task this is great. January 4, 2015
