12101342 - Tweco 21-62 WeldSkill Nozzle 2-Pack

Tweco 1210-1342 Replacement MIG Nozzles

Upgrade or replenish your welding supplies with the Tweco 1210-1342 WeldSkill Nozzle, Model 21-62. Sold in a value-oriented pack of two, these nozzles are an essential component for any welder using Tweco WeldSkill MIG guns. The nozzle features a 5/8-inch bore, which is the industry standard for many medium-duty welding applications. This size provides a generous envelope of shielding gas, effectively protecting the weld puddle from oxygen and nitrogen in the air, which can cause porosity and brittle welds.

Constructed from durable copper, the 21-62 nozzle excels at heat dissipation. During welding, the nozzle absorbs significant radiant heat from the arc; the high thermal conductivity of the copper helps prevent the nozzle from overheating and melting, while also reducing the adherence of weld spatter. When spatter does accumulate, the smooth surface finish makes it relatively easy to clean, especially when used in conjunction with anti-spatter dip or spray. The slip-on fitment ensures that the nozzle stays securely in place during welding but can be easily removed for contact tip changes or cleaning.

These nozzles are specifically designed for the Tweco 21 Series platform found on many WeldSkill guns. Whether you are working on automotive body panels, farm equipment, or general metal fabrication, having a fresh nozzle ensures your shielding gas is delivered exactly where it is needed. A damaged or clogged nozzle is a common cause of poor weld quality; replacing it with a genuine Tweco 21-62 restores optimal gas flow dynamics.

The package of two provides excellent convenience for the busy welder. Keep one on your torch and one in your toolbox as a backup. With Tweco's reputation for reliability and the WeldSkill line's focus on value, the 1210-1342 nozzle set is a smart investment for maintaining the performance of your MIG welding equipment.
