The ITW Miller Tregaskiss 403-27-35 is a heavy-duty, Extended Life (LF) contact tip from the TOUGH LOCK series designed for 0.035" (0.9 mm) wire. It features a tapered, high-conductivity copper alloy design and utilizes Dual Taper Technology to optimize heat dissipation and electrical conductivity. The tip is manufactured using a mandrel-drawn process to ensure precise tolerances and includes a locking feature to prevent loosening due to vibration. It is compatible with 404 series gas diffusers and can be used on Tregaskiss, Bernard, and other MIG gun brands via conversion adapters.
Features
Dual Taper Technology: Increases heat dissipation and maintains cooler contact tip temperatures
Taper Lock Design: Creates a secure, high-contact surface area between the tip and diffuser
Vibration Resistance: Locking feature prevents the tip and retaining head from loosening during operation
Mandrel-Drawn Construction: Controls tip tolerances for consistent wire feeding
Enhanced Conductivity: Large mating surface ensures optimal current transfer
Thermal Management: Improved heat transfer to the diffuser reduces wear and extends service life
