Tweco 3040-1103 Automation Mig Gun 400A 6 Ft

Product Description

The TWECO 3040-1103 is an air-cooled automation MIG gun and cable assembly rated at 400 amps at 60% duty cycle. Designed for automated welding applications, this unit ships as a complete assembly with a 6-foot cable and accepts wire sizes from 0.035 to 0.045 inches. The gun is field repairable and furnished with TWECO rear connector plugs, making it a practical choice for production environments where minimizing downtime matters. Welding automation integrators and maintenance technicians working on robotic or fixed-automation MIG cells are the primary installers of this assembly.

This gun assembly is suited for industrial automated MIG welding systems where consistent, high-amperage output is required over extended duty cycles. The 6-foot cable length accommodates typical reach requirements in fixed-automation and semi-automated welding cells. The unit comes standard with a 24CT-62S nozzle, a 54A gas diffuser, and a 14H series contact tip, so it is ready for installation without sourcing additional consumables separately. Applications include robotic welding fixtures and automated production line weld stations.

Key Features

• 400-amp rating at 60% duty cycle supports sustained high-output automated welding
• Accepts wire diameters from 0.035 to 0.045 inches
• Field-repairable design reduces downtime in production environments
• Furnished with TWECO rear connector plugs for direct integration
• Cabelhoz outer jacket is a tear-resistant, radiation cross-linked polymer extruded over copper stranding for durability and flexibility
• Hytrel center core tube supports copper stranding and provides flexibility; inner core serves as both shielding gas carrier and wire conduit support
• Includes 24CT-62S nozzle, 54A gas diffuser, and 14H series contact tip as standard

Compatibility

Designed as an OEM-style automation MIG gun assembly compatible with TWECO rear connector plug configurations in automated and robotic MIG welding systems.

Installation Notes

Installation is typically performed by a qualified welding systems integrator or maintenance technician. Disconnect and lock out all power to the welding power source and automation controller before connecting or disconnecting the gun assembly. Verify that the rear connector plug seats fully and that the cable is routed to avoid sharp bends or contact with hot surfaces during operation. Inspect the contact tip, nozzle, and gas diffuser after installation before resuming production.
