Is your MIG gun sputtering, feeding wire erratically, or overheating at the neck? It might be time to replace your conductor tube. The Tweco 64A-60 (part number 1640-1110) is the legendary 60-degree gooseneck found on the classic Tweco #4 and the popular Spray Master 450 MIG guns. Over time, conductor tubes can become bent, clogged with liner debris, or suffer from thread damage that ruins your gas flow and conductivity. Swapping out your old, beat-up neck for a fresh 64A-60 is one of the quickest ways to make an old gun feel brand new again.
The 60-degree angle on this tube is the industry favorite for a reason—it provides the perfect balance of reach and comfort for most bench work and out-of-position welding. Whether you are fabricating heavy structural steel or running long beads on pipe, this angle helps keep your wrist in a neutral position while allowing you to see the puddle clearly. The heavy-duty copper construction handles the heat of high-amperage spray transfer welding without breaking a sweat, ensuring that the power from your machine actually makes it to the wire.
Installation is straightforward for any welder familiar with Tweco gear. Simply loosen the set screw or locking nut at the handle, slide out the old tube (don't forget to check your liner length!), and insert the new 64A-60. It comes ready to accept your standard Tweco diffusers, tips, and nozzles, so you don't have to change your entire consumable inventory just to fix the torch body. The durable outer insulation stands up to the rough and tumble of the shop floor, resisting cuts and burns that would short out lesser equipment.
Don't let a bad neck ruin your welds or your day. A compromised conductor tube can lead to micro-arcing inside the gun, which destroys liners and causes frustrating bird-nests. By keeping a spare Tweco 64A-60 in your tool crib, you ensure that you are always ready to tackle heavy fabrication jobs with a torch that performs as good as it looks. Trust genuine Tweco parts to keep your arc smooth and your production line moving.
