Plasma Cutting-The use of an electric arc to cut metal.

It is very widely used on all types of metal to achieve high-quality cuts and high levels of productivity. Under certain circumstances, it can achieve a comparable quality level to laser cutting, but at considerably lower production cost.

INWELT can offers different types of Plasma cutting manual power sources, such as our LT & PT ranges.

Anyway Plasma is mostly used in automation, so we have also a wide range of automated installations to answer the most demanding needs.

Principle of the process

Plasma cutting uses the 'transferred arc' mode. The arc is constricted between the electrode and the material to be cut, due to the gas flow used, causing the energy flow density and the temperature of the plasma jet to rise even further.

The gas flow consists of active or inert gases or gas mixtures.

(FAQ): Manual & Automated Plasma Cutting Torches

Q1: What is the difference between manual and automated plasma cutting torches?

A: Manual Plasma Torches are handheld tools ideal for flexibility in repair shops, construction sites, or artistic metalwork. They prioritize portability and ease of use.

• Automated Plasma Torches are integrated into CNC machines or robotic arms for high-precision, repeatable cuts in industrial manufacturing (e.g., automotive, aerospace). They deliver faster speeds (±0.2mm accuracy) and reduced operator fatigue.

Q2: What materials and thicknesses can your plasma cutters handle?

A: Our systems cut conductive metals up to 50mm thickness, including:

• Mild steel, stainless steel, aluminum. Copper, brass, and galvanized steel.

Automated models support piercing up to 25mm with PMX-compatible consumables for clean edges.

Q3: How does automated plasma cutting improve efficiency?

A: Automated torches feature:

• AI-driven arc stability to reduce dross and rework.

• Collision avoidance sensors for uninterrupted 24/7 production.

• 30% faster cutting speeds vs. manual operation (e.g., 8m/min on 10mm steel).
  This minimizes material waste and labor costs.

Q4: Are these torches safe for indoor use?

A: Yes. All models include:

• High-frequency (HF) noise suppression to protect electronics.

• Fume extraction compatibility (ISO 15012-4 compliant).

• IP54-rated components to resist dust and splatter.
  Automated systems add emergency stop and thermal overload protection.

Q5: What power supply is required?

• A: Manual Torches: 110V–240V AC, 30–80A (portable for generators).

• Automated Torches: 3-phase 380V–480V, 100–400A (industrial-grade).
  Both support IGBT inverter technology for 85% energy efficiency.

Q6: How long do consumables (nozzles, electrodes) last?

• A: Lifespan varies by material and amperage:

• Manual Torches: 1,500–3,000 starts (copper nozzles) or 500+ pierces (hafnium electrodes).

• Automated Torches: 2x lifespan due to optimized gas flow (argon/hydrogen mixes).
  A real-time wear monitor alerts users to replace parts before quality degrades.

Q7: Can beginners use these systems effectively?

A: Absolutely.

• Manual Torches: Include drag-and-cut technology for steady hands-free operation.

• Automated Torches: Preloaded cutting profiles (e.g., DXF files) simplify setup.
  Free online training covers safety, maintenance, and troubleshooting.

Q8: What certifications do your products hold?

A: We comply with:

• EU: CE, RoHS, EN 60974-7 (arc welding equipment).

• US: UL ANSI Z49.1 (safety in welding/cutting).

• Global: ISO 9001 (quality management).

Q9: What warranty and support do you offer?

A: 3-year limited warranty.

• 24/7 online technical support.
