[ENHANCED CUTTING CAPACITY] - Equipped with a 3nd-Gen MCU, this plasma cutter delivers powerful output across both voltage options. On 120V, it supports a cutting range of 10–16 mm when the air pressure is kept above 55 PSI. Switching to 240V unlocks heavier performance, cutting 16–26 mm (up to 15/16" / 24 mm) with the recommended 55–75 PSI air pressure. The arc remains stable on stainless steel, carbon steel, aluminum, and copper, producing smooth edges with minimal slag and reducing follow-up grinding.

If pressure drops below 20 PSI, the machine triggers an E80 warning; if it rises above 80 PSI, it shows E81 to prevent unsafe operation. Before cutting, you can switch to pressure-detection mode to ensure the pressure stays within the recommended range. [Recommended pressure: 0.3–0.55 MPa or 0.4 MPa (57.5 PSI)]
[ADVANCED PILOT ARC & TORCH CONTROLS] - Customize performance with adjustable pilot arc duration—extend time for mesh cutting or shorten it to conserve consumables. Post-flow time (5–15 s) keeps the torch cool and extends its lifespan. Choose 2T for short, quick cuts or 4T for reduced fatigue during long passes.

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
