Size: STC850P MAX
Features
- CNC Function: The STC850P MAX plasma cutter machine is equipped with blowback technology and Non-HF (non-high frequency) pilot arc, which are compatible with CNC systems. This setup minimizes the risk of high-frequency signal interference, thereby improving cutting stability. The non-touch blow-back pilot arc initiation ensures that the arc starts without the need for physical contact with the metal. The plasma cutter features two connection ports: a 2-pin connector for arc voltage output at 1:1 ratio and 5-pin connector for signal control. This design facilitates seamless integration with CNC cutting tables
- Powerful Cutting Ability: This blowback pilot arc plasma cutter from SILATU includes an automatic voltage detection system that works with both 110V and 220V inputs, operating on a single-phase power supply with a 60% duty cycle. It is optimized for cutting materials up to 15mm thick at 40A on 110V with 60 PSI air pressure, and up to 35mm thick at 85A on 220V with 70 PSI. For electrical safety, it requires a big current circuit breaker for 110V operation and a 50A breaker for 220V. The versatility of this SILATU plasma cutter makes it suitable for a wide range of materials, including stainless steel, alloy steel, mild steel, copper, aluminum, etc
- Air Sensor Technology: An integrated air sensor displays the air pressure on the machine's front panel. Users can manually adjust the air pressure using the air regulator, as automatic adjustment is not available. An air filter is installed at the rear of the unit, featuring a quick-connect 1/4 NPT air fitting for easy setup. When connected to an air compressor, the recommended air pressure should be set to around 70 PSI, with a flow rate of approximately 250 liters per minute(Note: Purchase the air compressor separately)
- PT/2T/4T/PA Function: The post-flow cooling time, adjustable between 3 and 15 seconds, extend the life of the torch head and consumables. The 2T mode offers semi-automatic control over the torch trigger, whereas the 4T mode enables fully automatic triggering, freeing the operator's hand. The PA setting adjusts the duration of the pilot arc. Additionally, the SILATU plasma cutter model STC850P MAX incorporates a mesh cutting mode designed to prevent arc interruption when cutting mesh materials
- CNC Cutting Torch: Under the CNC function, we recommend using a straight torch, which is an optional accessory and not a standard component. The straight torch offers greater convenience, although it comes at a higher cost. We recommend either the PTM80 or the PTM60 models. Of course, the handheld cutting torch that comes with the machine can also be used with the CNC system, it just needs to be securely fastened

This plasma cutter has been a great addition to my shop. It starts reliably, cuts cleanly, and handles both 110V and 220V without any hassle. I really like the pilot arc feature because it makes cutting smoother, especially on metal that is rusty or not perfectly clean. The digital screen is also very helpful since it shows the pressure, voltage, and current clearly, so setup is quick and straightforward. The 2T and 4T modes are a nice bonus, and the machine feels practical for both short jobs and longer cutting tasks. Overall, it’s a strong, easy-to-use cutter that delivers very good performance for the price.

This plasma cutter really exceeded my expectations. It’s easy to set up right out of the box, and the dual voltage feature works great with both my workshop and garage outlets. The LED display is bright and accurate, making it simple to adjust settings. The HF non-touch pilot arc cuts cleanly through various metals without slag or burn marks, even on thicker pieces. I’ve used it for a few DIY fabrication projects, and the results have been impressive every time. Reliable, smooth, and definitely worth the price—highly recommend for beginners and hobby welders alike.

Made several cuts & so far happy happy with the results. I like the pilot ark feature well worth the $ for my needs. Just a hobbyists playing with projects around the house. Now what can I make ?

Cuts nice but the instructions are lacking. Does anyone know how to hook up the signal control for the trigger?

So far, this thing is incredible. I hesitated for a long time to buy one of these budget plasma cutters. I had such a good experience with a budget Chinese welding machine, though, that I decided to give a plasma cutter a try. This Silatu 55A cutter is cheaper than most on Amazon and has good reviews, so I decided to give it a try. Some things to note: it's small and lightweight, which is nice. The power cord isn't real long, so you'll need an extension cord if you plan to move it around your shop. You need a large air compressor. I'm running a 26 gal Craftsman compressor, and it kicked on every 5 minutes or so while I was using it for the first time for about an hour. This thing cuts like butter through about anything that a DIYer in his/her garage shop would throw at it. In fact, I had the amperage and air pressure cranked all the way up, and it cut through 1/4 steel a little too fast. Once I turned both down, it was controllable and still cut really well. I've not tested it on 1/2 steel, but I'm sure it would do fine. That's all on 220, by the way. I've not tried it on 110, and I probably won't. As reviewers have noted on here and on Youtube, you won't get the full power and capability on 110. It is nice to be able to use it on 110 if you're in a pinch, though. One note on the HF Non-touch feature. Pay attention to this. There are cutters that require contact with the metal and the cutter tip. Those require the metal to be free of paint and/or rust. This one, though, does not require contact (and has the metal frame thing around the tip to provide space). That's an important feature that's worth paying a bit extra for if need be. I have cut through steel covered in paint and rusted steel just fine with this one. Amazing. Overall, you can't go wrong with this budget plasma cutter. I'm a DIYer who works in my woodshop and metal shop in the evenings and on the weekends. I'm no expert, but I'm guessing I'm just the type of guy who would buy this. I can't speak to the durability of the machine, but I'm hopeful it will last a long time at the rate at which I use it. If I get 5 years out of a $115 plasma cutter, I'll be overjoyed.

I know very little about cutting metal or welding, but learning. And one thing I have learned is that this plasma cutter is top shelf. Still learning how to use it, but love it so far. The air supply took a bit to put together, but instructions were clear. A good buy.

You do not want to pass this up this is a real Beast. It chews through 5/8 inch steel like a hot knife through butter I have a 50 amp plasma cutter that just does not compare this is the real deal.
