The 1.4mm Back Striking Contact Tip is a high capacity plasma consumable engineered for heavy duty industrial applications. Optimised for the 80-90 Amp range, the 1.4mm orifice allows for a massive flow of plasma gas, providing the thermal energy required to pierce and cut through heavy carbon steel, stainless steel, and aluminium plate.
Built for torches utilising Back Striking (Blow Back) ignition technology, this tip ensures a reliable pilot arc without the need for high frequency (HF) interference. This makes it the standard choice for high amperage CNC plasma tables and industrial workshops that must protect sensitive electronic equipment from electromagnetic noise. Constructed from premium, high density copper, this tip is built to withstand the extreme temperatures of a 90A arc, maintaining its orifice integrity for squarer cuts and reduced secondary grinding.
Key Features
High Amperage 80-90A Capacity: Engineered to handle the intense thermal loads of high power plasma systems.
Back Striking Ignition: Designed for blow back start torches, ensuring consistent starts and reducing electronic "noise" on CNC systems.
Industrial 1.4mm Orifice: Provides a wide, powerful plasma jet for fast travel speeds and maximum penetration on thick plate.
Heavy Plate Specialist: The ideal consumable for structural steelwork, heavy equipment repair, and shipbuilding.
Premium Copper Construction: Exceptional thermal and electrical conductivity for a stable arc and extended tip life.
Reduced Bevelling: Precision machined to ensure a centred, laminar gas flow for cleaner edges on vertical cuts.
