11401202 - Tweco 14H-35 Heavy Duty Contact Tip .035 (25-Pack)

Tweco 14H-35 Heavy Duty Contact Tips (25-Pack)

Upgrade your MIG gun consumables with the Tweco 14H-35 Contact Tip, a heavy-duty solution for 0.035" wire welding applications. This package includes 25 high-quality copper tips, identified by the stock number 1140-1202. As part of the renowned Tweco 14 Series, these tips are the industry standard for medium to heavy amperage welding, fitting seamlessly into Tweco #2, #3, and #4 MIG guns, as well as compatible systems like the Lincoln Magnum 200-400 series.

Heavy-Duty Construction for Extended Life

In high-amperage or high-duty-cycle welding, heat is the enemy of consumable life. The 14H-35 distinguishes itself with a heavy-duty profile (0.250" Outside Diameter), offering a substantial improvement over standard thin-wall tips. The increased copper volume acts as a superior heat sink, drawing thermal energy away from the wire exit point. This results in reduced spatter adhesion, less frequent burn-backs, and a longer service life per tip. For shops focused on efficiency, this means fewer tip changes and more arc-on time.

Precision and Compatibility

Electrical conductivity is paramount in GMAW (MIG) welding. Tweco manufactures these tips with tight tolerances to ensure the bore diameter provides optimal contact with the welding wire without causing drag. This consistent electrical transfer is critical for maintaining arc stability and preventing micro-arcing inside the tip. The 14H-35 is threaded with a 1/4"-28 UNF base, ensuring a secure fit into standard gas diffusers. Whether you are welding mild steel, stainless, or using flux-cored wires, these tips provide the reliability required for code-quality welds. Invest in genuine Tweco parts to maximize the performance of your welding equipment.
