RIVERWELD PT-31 Plasma Cutting Torch Head Body 20072 for CUT 40 50 CT-312 Plasma Cutter

There are two sections to this review. The quality and the installationQUALITY:Overall this replacement torch is very sound and feels very durable. The product is well made. It is sturdy and comfortable to hold in your hand.There isn’t a safety cover over the button. If you barley push it and it turns on. Would this be good with someone starting out? Yes. As long as they remember safety. Would this be good for someone with experience, most definitely.Would I recommend the replacement, yes IF AND ONLY IF IT IS COMPATIBLE WITH YOUR O2 LINEINSTALLATION:I mainly purchased for the spacer. I wanted to use the original torch that came with my welder and I didn’t want a spacer that dragged on the surface I was cutting nor was I able to locate a double roller spacer made for the PT-31 under $15. I attempted to first install the roller but the diameter was too small. I figured it would have fit because it came with another PT-31. It did not. I noticed the diameter on the description later. Then I thought I would switch out just the heads. My version of the PT-31 has notches around the top that the head uses to slide into the handle. That wouldn’t work unless I filed the head down on the sides. Then I decided to go ahead, and switch out the handles. I unsoldered the switch on my OE torch. The. soldered it to the replacement.Everything was good. I was getting excited, then I went to install the head on the O2 line and found that the screw on spacer/head holder they include doesn’t allow you to tighten the nut on the line. It makes the line sit too far in. The nut on the incoming line has a swiveling nut so all it did was spin. The copper connector wasn’t long enough to push all the way through to let you tighten the coupler. I decided that I’d cut the spacer but before I did, I realized it held the head in between two plastic clips molded in the handle. If I cut it the head could pull on the O2 line and possible pull out, push in, or twist easily.I ended up put everything back in the original handle and decided to file the head to a square so it would fit in my OE handle since I was passed the return date.It took some time. I was able to get it to sit in my torch handle. Everything lined up well and works.After changing the head out I hit the tips mixed up but as I sat there playing with them discovered the tips were different and didn’t interchange between the two heads.I thought I should have returned it. Now I have to replace all my tips.I checked the listing for the tip types and discovered I could have returned it. Good job, Remedy!All of that said:1. If you want the rolling spacer, check the internal diameter of your head. Not the ceramic piece. the actual plastic portion.2. If you decide to use the whole torch in place of yours verify your O2 line will fit before you unsolder the switch.3. If you decide to modify it to fit your current one make sure the tips are interchangeable.4. Return it if you are not comfortable modifying the head to fit yours.The last photo shows the spacer and riverweld handle. The riverweld head stopped at the indented portion and did not come out as far as the original.

Excelente

great product works good . great for the price

It will work for me a hobbyist not heavey enough for pro

I bought this product in the hopes of using it with my LT5000D plasma cutter. However, I found that the gas fitting on the LT5000D is larger than the fitting on a normal PT-31 torch head. This product, while identical in outward appearance, feels more solidly build in the hand than the LT5000D torch. To use this with a LT5000D plasma cutter you will need to change the gas fitting to one that's compatible with the LT5000D gas line.Optionally, I suppose you could modify a complete PT-31 torch assembly (lines included) to make it fit the gas and electrical connections on the LT5000D chassis.

I bought this plasma head unit, so I can use it with my lotos lt3500, because their consumables are to expensive. Easy to switch out. And worked great.With a slight modification i wanted to use the gun casing from the lotos, because I like the trigger on it. Here are a few pics of how I converted it.and the good thing about this is i can use lotos or most any consumables.2nd pic shows the blue one now has the lotos lt3500 internals and the red one is the one I can use now with most any consumables.3rd pic shows the internals before the switch.Last pic shows the top one is the lt3500 head.Lower is the esab

AWESOME

I have a yellow "CUT 50" from fleabay. The ceramic cup broke, the internals were contaminated with slag, and the switch wasn't staying in place.It took about half an hour to adapt and install this. It's working much better than the contaminated original. The switch could be better: it has a mushy feel and sometimes my cut doesn't start and I have to realign and start over.

Air seal terrible, arced onto guide on first try, no use... Cup Not interchangeable with other pt31 ones..

The torch itself is great for the money but the spares that come with it don't seem to want to get a decent touchdown no matter what setting I use but still worth the price

very good torch works well

Absolutely brilliant and great price also.

The delivery time was good, only half the product arrived disapointed, no time to return , due no time,
