SILATU 65A CNC Plasma Cutter
The SILATU 65A plasma cutter is designed for CNC work, combining blow-back pilot arc with a non-HF start to minimize interference with CNC control systems. It supports 110V or 220V input with automatic voltage detection and a 60% duty cycle, enabling versatile operation on a single-phase supply. The unit provides two connectors—a 2-pin arc voltage output and a 5-pin control interface—facilitating straightforward connection to CNC cutting tables. In 110V mode, it cuts materials up to about 14 mm (0.55 in) at 40 A with 45 PSI air; at 220V, up to 25 mm (1 in) at 65 A with 70 PSI. An air pressure display and a rear air filter with a 1/4 NPT quick-connect aid setup. Compressor not included.
bestarc 80A Non-HF CNC Plasma Cutter
bestarc’s 80A non-HF CNC plasma cutter is built for demanding CNC workflows with dual voltage operation (110/220V) and inverter IGBT technology for clean cuts on iron, steel, aluminum, and copper. It can handle up to 5/8″ (16 mm) at 110V and about 1.57″ (40 mm) at 220V under proper air pressure (around 70 PSI, 250 L/min). The unit features a blow-back pilot arc that reduces high-frequency EMI and supports CNC table starts without touching the metal. An integrated air sensor shows pressure on the front panel, and a rear filter with quick-connect 1/4 NPT simplifies setup. Compressor not included.
LOTOS LTP6300DCNC 63A CNC Plasma Cutter
LOTOS LTP6300DCNC is a CNC-enabled plasma cutter with 63A cutting power and non-HF blowback start plus pilot arc for reliable starts on painted or rusty metals—great for workshop reliability. It includes pre-installed CNC port outputs for Torch Height Control (THC) and ARC OK signals, enabling straightforward hookup to most controller boards. The unit handles up to 3/4″ (19 mm) clean cuts and 1″ (25 mm) severance, with 110V/220V input. Drag cut capability helps maintain kerf control on shop floors. Built-in air regulation and filtration plus a 1/4 NPT quick-connect support fast, clean setup.
bestarc 50A CNC Plasma Cutter
Bestarc’s 50A plasma cutter offers a compact, CNC-friendly option suitable for beginners and hobbyists. It runs on 110/220V and supports a clean cut up to 1/2″ (12 mm) at 110V or 3/4″ (18 mm) at 220V, with a safe power limit of 40A at 110V and 30A at 220V. It uses a pilot arc with non-HF start and includes an air sensor plus a rear filter; manual air pressure adjustment via the regulator ensures stable starts. The unit is designed to integrate with CNC cutting tables for automated workflows; compressor not included.
GZ GUOZHI 55A CNC Plasma Cutter
GZ GUOZHI’s 55A non-HF plasma cutter emphasizes CNC readiness with non-touch pilot arc and Torch Height Control (THC) enabled interfaces. It supports dual voltage (110/220V) inputs and can cut up to approximately 1.2 inches (30 mm) while delivering clean, rapid cuts on stainless steel, alloy steel, mild steel, copper, aluminum, and more. A safety feature is an automatic drainage function to protect electrodes and nozzle. It offers 2T/4T modes for easier operation and a straightforward air regulation setup via a rear quick-connect; compressor not included.
Buying Guide
Key purchase considerations
- Cutting thickness and materials: Match the machine’s maximum clean cut and severance capability to the materials you routinely work with (steel, stainless, aluminum, copper, etc.).
- CNC readiness: Look for THC or ARC OK signals, CNC ports, and compatibility with your controller or breakout board.
- Start method and EMI: Non-HF, blow-back pilot arc reduces interference with CNC systems, improving stability on automated setups.
- Voltage flexibility: Dual-voltage models simplify installation and future-proof a workshop that may change power supply; confirm if automatic voltage detection is present.
- Air system requirements: Verify required air pressure and flow (PSI and LPM), and whether an external air compressor is included or must be purchased separately.
- Controls and feedback: Front-panel air pressure display and built-in regulators ease setup and ongoing operation in variable shop environments.
- Consumables and maintenance: Consider electrode/nozzle life, availability of replacement parts, and ease of servicing.
- Safety and certifications: Ensure protective features, proper grounding, and user safety guidelines align with your shop’s policies.
