Contact Tip 0.035 Tweco Heavy Duty
Radnor contact tips come in a 25-piece pack for MIG welding guns that accept the Tweco-style 14H35 series. The copper construction suits general fabrication and repair work where a 0.035-inch wire diameter is specified.
Installing the tips
Thread each tip into the diffuser until it seats firmly; a loose fit causes arcing and uneven wire feed. Over-tightening strips the soft copper threads, so stop when resistance rises sharply rather than applying maximum force.
Practical limits of the 14H35 series
The tip bore matches 0.035-inch solid or flux-cored wire only; larger diameters will not feed and smaller wire increases burn-back risk. Copper wears faster than chrome-zirconium alloys, so high-amperage or continuous-duty cycles demand more frequent tip changes.

Questions about this item
How do I confirm the Series 14H35 contact tip is performing correctly after installation?
After fitting a tip from the Series 14H35 pack, start the welder and check that the wire feeds smoothly through the .035 copper tip without sticking or burning back into the contact surface.
What comes in the Radnor Contact Tip 0.035 Tweco Heavy Duty PK25 package and what must I supply myself?
The box contains 25 copper contact tips stamped Series 14H35 for .035 wire; you must provide a compatible Tweco-style heavy-duty welding gun, drive rolls and shielding gas.
Which version should I choose between the Series 14H35 .035 tip and other Radnor contact tips?
Select the Series 14H35 .035 copper tip when your welding gun takes Tweco heavy-duty consumables and you are running .035 diameter wire; other Radnor series fit different gun styles or wire sizes.
