Product Details

Tungsten Electrode Set Screws for AMI Orbital Fusion Heads

Maintain consistent arc gaps and dependable weld repeatability with our replacement set screws. Built to serve as direct replacements for standard Arc Machines, Inc. (AMI) hardware, these 18-8 Stainless Steel fasteners ensure your tungsten electrode remains firmly locked inside the rotor assembly throughout the automated welding cycle.

Reliable Clamping for Orbital Hardware

Automated tube welding setups require reliable electrode security to prevent rotation issues. These replacement clamping screws feature a deep socket pocket that accepts a standard 1/16" hex key wrench, giving operators the positive engagement needed to apply uniform torque against the tungsten electrode. This reduces common field problems like slipping, arc gap drift, or thread seizing within the housing components.

Key Features:

  • Secure Electrode Holding: Cup point tip design bites cleanly into the tungsten welding electrode to prevent shifting during rotation.
  • Standard Hex Drive: Features a 1/16" socket drive pocket to ensure easy adjustments with standard shop allen wrenches or torque tools.
  • Standard Fit: Sized to thread smoothly into standard rotor assemblies and tungsten extenders with no modifications required.
  • Flush Seating: Seats properly within the internal gear components to eliminate the risk of rotational interference inside the closed weld head chamber.
