S-Gun 250 amp Semi-Automatic Air-Cooled MIG Guns

The Bernard® S-Gun™ 250 amp MIG gun is designed to meet the needs of the shipbuilding and construction industries. This semi-automatic air-cooled MIG gun offers a locked rotatable neck that cannot be easily removed by the welding operator, but is still readily serviceable by maintenance personnel. This means that welders will spend less time looking for or replacing MIG gun necks at the beginning of their shift.

  • Features a steel monocoil cable for superior wire feedability
  • The locked rotatable neck is easily serviceable by maintenance and eliminates downtime at start of shift due to missing necks resulting in reduced operator costs
  • Back end with durable rigid strain relief; easily interchangeable direct plugs and trigger leads connect to wire feeders and machines from major manufacturers and allow simple maintenance
  • Unicable equipped with Stay-Tite™ technology and internal gas hose that resists kinking, and improves gas flow and feedability
  • Jump liner allows for replacement of only most commonly worn or clogged liner area, which reduces the amount of time a gun is offline and minimizes inventory
