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. ### ⭐⭐⭐⭐ Valorar *by J***N on Reviewed in the United States on July 5, 2022* Excelente ### ⭐⭐⭐⭐⭐ great product for the money *by B***L on Reviewed in the United States on July 10, 2022* great product works good . great for the price --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/26698994-riverweld-pt-31-plasma-cutting-torch-head-body-20072-cut](https://www.desertcart.co.th/products/26698994-riverweld-pt-31-plasma-cutting-torch-head-body-20072-cut) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
