Main Consumables and Spare Parts

Main Consumable

The consumables for the Unitorch EL120 plasma torch are designed to ensure optimal cutting performance, extended consumable life, and consistent arc stability. These components wear over time and need periodic replacement depending on usage intensity and material type.

Key Consumables:

Electrodes
- Function: Conduct the electrical arc and transfer current to the workpiece.
- Material: Usually made of copper with a hafnium or thoriated insert for enhanced arc stability and durability.
- Replacement triggers: Arc instability, poor cut quality, or visible wear.
Nozzles (Tips)
- Function: Shape and constrict the plasma arc to increase cutting precision and focus.
- Variants: Available in multiple o rifice sizes to suit different material thicknesses.
- Material: High-grade copper for heat resistance and conductivity.
Swirl Rings
- Function: Control the flow of plasma gas to stabilize and cool the plasma arc.
- Material: Typically made from ceramic or heat-resistant composite materials.
Retaining Caps
- Function: Hold the electrode and nozzle securely in place within the torch head.
- Material: Heat-resistant plastics or composites.
Shield Cups
- Function: Protect consumables and the workpiece from spatter and improve gas flow.
- Material: Heat-resistant materials designed to withstand high temperatures and impact.

Note:
Consumable life varies based on cutting parameters, material type, and operator technique. Regular inspection and timely replacement help maintain cut quality and torch longevity.
