996105 - ESAB 996105 Contact Tip 3/64 for ST Torches (5-Pack)

Keep Your Arc Smooth and Your Bead Straight

Every welder knows that the contact tip is the unsung hero of the MIG gun. It takes the most abuse, handles the most heat, and is usually the first thing to blame when your machine starts acting up. If you are running 3/64" wire through an ESAB ST-style torch, the ESAB 996105 Contact Tube is the exact replacement you need to get back to laying down smooth beads. These aren't generic knock-offs; they are genuine ESAB parts designed to handle the heat and current your machine puts out.

Why does a fresh tip matter? Over time, the wire sliding through your tip wears out the hole, turning it into an oval shape. This "keyholing" ruins your electrical connection. One second you have a hot arc, the next it's sputtering and popping because the wire is losing contact inside the tip. This leads to erratic feeding, ugly spatter, and frustrating burn-backs that weld the wire right to the gun. Swapping in a fresh 996105 tube restores that tight electrical connection, ensuring the current transfers smoothly to the wire so you can focus on your puddle control rather than fighting your equipment.

This pack comes with five contact tubes, which is perfect for the toolbox. You never want to be down to your last tip on a Friday afternoon when a job needs to go out. Having a 5-pack on hand means you can swap them out the moment you suspect wear, keeping your welds clean and consistent. Whether you are welding aluminum, mild steel, or stainless, if you are using 3/64" wire, these tips are the correct size to prevent binding while ensuring good contact.

Don't let a worn-out $5 part ruin a critical weld or waste hours of your time troubleshooting. These copper tubes are built to withstand the thermal shock of start-stops and the friction of high wire feed speeds. Pop a new one in your ST gun, check your drive rolls, and get back to welding with confidence. Reliable, durable, and essential for any serious fabricator using ESAB gear.
