Tweco 1023-1140 Mig Gun 250A Air Cooled 12 Ft

Product Description

The TWECO 1023-1140 is a 250-amp, air-cooled MIG gun from the Tweco Spray Master Series, designed for demanding spray transfer and pulse welding applications. It accepts wire sizes from 0.035 to 0.045 inches and comes with a 12-foot cable. The gun delivers an 80% duty cycle when used with argon/CO2 or mixed gas, making it suitable for sustained production welding. A heavy-duty, thick-walled contact tip and diffuser extend consumable life and reduce downtime during tip changes. The compact, ergonomic handle is balanced at its center to ease positioning across multiple weld angles and reduce operator fatigue during long shifts.

This gun is built for professional welders in fabrication shops, maintenance and repair operations, and production environments. The standard 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced without disturbing the conduit, keeping workflow efficient. A fully insulated Mig-Kwik rear connection with a simplified direct rear plug allows quick connect and disconnect at the wire feeder. The extended trigger keeps the operator's hand farther from the arc, reducing radiated heat exposure. Applications include farm, garage, shop jobs, artistic metalworking, and general maintenance and repair.

Key Features

• 250A rating with 80% duty cycle at argon/CO2 or mixed gas
• Accepts wire sizes 0.035 to 0.045 inches
• Thick-walled, three-layer conductor tube acts as a heat sink and improves electrical conductivity
• 360-degree swivel conductor tube removable without removing the conduit
• Fully insulated Mig-Kwik connection for fast connect and disconnect at the wire feeder
• Steel spring strain relief front and rear to minimize wire feed issues
• Split-half handle case for field-repairable access to internal components

Compatibility

Designed as an OEM-style replacement or direct-install MIG gun for wire feeders equipped with a standard Tweco rear connection. Front-end consumables are interchangeable with Tweco Classic No. Series and Tweco Spray Master Series guns, reducing spare parts inventory requirements.

Installation Notes

Installation should be performed by a qualified welding technician or trained operator. Disconnect and power down the wire feeder before connecting or removing the gun at the feeder plug. Verify the conductor tube angle and swivel position are locked before initiating a weld. Follow applicable AWS safety standards and the wire feeder manufacturer's guidelines for cable and connection specifications.
