The Hard Core HC300/400 M8 Contact Tip is the premier choice for high amperage MIG/MAG welding. Specifically designed for the HC300 and HC400 torch series, these tips feature a robust M8 threading, providing superior electrical conductivity and a more secure mechanical fit than standard M6 alternatives. This increased mass allows for significantly better heat dissipation, making them ideal for high duty cycle spray transfer and pulse welding.
Available in a comprehensive range of sizes to suit any wire diameter:
- 0.8mm & 1.0mm: Perfect for precision fabrication and automotive assembly.
1.2mm: The industrial standard for general structural steel and heavy duty manufacturing.
- 1.4mm & 1.6mm: Engineered for high deposition welding on thick plate and large scale structural components.
Each tip is precision machined from a specialised, high density alloy designed to resist "keyholing" and wire micro welding. This results in a more stable arc, reduced spatter, and a much longer service life compared to economy grade consumables.
Sold in packs 25 - great for everyday use or stocking.
Key Features
Heavy Duty M8 Threading: Enhanced surface area for better current transfer and cooler operation.
HC300 & HC400 Compatibility: Designed as a direct fit for Hard Core industrial MIG torches.
Extreme Heat Resistance: Formulated to maintain structural integrity during long, high amperage welding runs.
Precision Bored Orifices: Ensures smooth wire feeding and minimises "burn back" for more consistent arc starts.
Full Size Spectrum: Available in 0.8mm, 1.0mm, 1.2mm, 1.4mm, and 1.6mm to cover all industrial wire diameters.
Extended Service Life: Reduces downtime by lasting longer under the abrasive friction of hard facing or flux cored wires.
