OVERVIEW

Professional Grade MIG Gun Adapter for Fabricator Series

Welders seeking to enhance their equipment setup know that the connection between the machine and the torch is critical. The Tweco W7004966 Adapter is the specific solution designed to mate the popular Fabricator 141i and 181i power sources with the industry-standard Tweco #4 MIG gun backend. This component is vital for shops and hobbyists who wish to move beyond the proprietary or stock torches included with their machines.

Seamless Integration

The Fabricator series of welders are workhorses in the light-industrial category. However, consumables and torch preferences vary wildly among operators. This adapter converts the machine's output receptacle to accept a Tweco #4 power pin. This means you can easily attach a more robust gun, potentially with a longer cable or different neck angle, to better suit your workspace. The adapter handles the transfer of welding current, shielding gas, and trigger signals reliably, maintaining the integrity of the arc.

Robust Construction

Cheap adapters can lead to resistance heating, poor arc starts, and gas wastage. The W7004966 is constructed from high-grade brass and durable polymers to resist thermal expansion and mechanical wear. It locks securely into the wire feeder mechanism, providing a stable platform for the gun. This stability is crucial for consistent wire feeding, especially when using softer wires like aluminum or when welding in out-of-position scenarios.

Application

This part is ideal for:

  • Repair and Maintenance: Replacing a broken stock gun with a readily available Tweco #4 unit.
  • Fabrication Shops: Standardizing all MIG guns in the shop to Tweco #4 for easier consumable management.
  • Custom Setups: Users who require specialized gun lengths or heavy-duty cycles not offered by the stock equipment.

Don't let a proprietary connection limit your welding capabilities. The Tweco W7004966 Adapter gives you the power of choice and the reliability of the Tweco brand.

FAQ

The W7004966 adapter is specifically designed for use with the Thermal Arc / ESAB Fabricator 141i and Fabricator 181i multi-process welding machines.

This adapter allows you to connect any MIG gun that features a standard Tweco #4 backend connection (power pin) to your Fabricator machine.

No, this product is the adapter only. The MIG gun must be purchased separately.

Yes, this is a genuine OEM part manufactured by ESAB/Tweco, ensuring perfect fitment and safety.

You would need this adapter if you wish to replace the stock Fusion gun that came with your welder with a standard Tweco style gun, which may offer better durability or consumable availability.

While the 211i is in the same family, this part is explicitly listed for the 141i and 181i. Please check your 211i manual or parts list to confirm if it shares the same adapter part number.

Installation is generally straightforward and involves seating the adapter into the machine's drive roll area. Always disconnect power before installing.

Yes, the adapter is designed to pass shielding gas through to the gun, provided the O-rings and connections are properly seated.
