Item Details

  • The PROFAX 64007046 (OEM 16-500) is a replacement MIG gun trigger housing assembly designed for the Profax 1260 series and industrial self-shielded, flux-cored (SSFC) arc welding guns. It consists of a split-shell dual-clamp housing that isolates internal electromechanical components, including a silver-plated contact block and an ergonomic trigger lever, to facilitate arc activation in heavy industrial environments.

Features

  • Zero-flex split-shell engineering prevents handle twisting or separation under cable tension
  • Self-cleaning mechanical contacts utilize micro-wiping action to clear airborne particulate and flux dust
  • Ergo-curve blade design reduces finger pulling force for continuous welding runs
  • Integrated safety guard overlap protects trigger from accidental activation if dropped
  • Direct drop-in maintenance design with molded wire routing channels to prevent pinched leads
  • Silver-plated contacts prevent oxidative skin resistance and surface pitting
