Tweco 1140-1440 Robotic Contact Tip 0.035 in 400A 25 Pack

Product Description

The TWECO 1140-1440 is a robotic MIG welding contact tip rated for heavy-duty applications up to 400 amps. Designed to accommodate 0.035-inch wire diameter, this contact tip delivers consistent electrical conductivity to maintain arc stability and protect weld quality. The part number and wire diameter are marked directly on the tip for fast identification during changeover. Each pack contains 25 tips, making it a practical stocking unit for high-volume robotic welding operations. Licensed welding technicians and robotic cell operators rely on this tip to sustain production uptime in demanding industrial environments.

This contact tip is suited for robotic MIG welding setups running 0.035-inch wire in heavy-duty industrial and manufacturing applications. At a 400-amp rating, it handles sustained high-current duty cycles common in automated welding cells. The compact dimensions — 1.5 inches in length and 0.3 inches in width — fit standard robotic MIG gun configurations. It is sold in a 25-count pack, appropriate for scheduled maintenance intervals or bulk consumable inventory.

Compatibility

Designed as an OEM-style robotic MIG welding contact tip for use with 0.035-inch wire in heavy-duty gun assemblies rated up to 400 amps.

Installation Notes

Contact tip replacement is performed by welding technicians or robotic cell maintenance personnel. Always power down the welding power source and allow the gun to cool before replacing a contact tip. Use the appropriate tip wrench or pliers to avoid cross-threading; do not overtighten, as this can restrict wire feed and cause premature tip failure. Inspect the gas diffuser and nozzle for spatter buildup during each tip change interval.
