  If the Tweco Soldering Gun drive rolls are turning but the wire isn't feeding, consider these potential causes and solutions: * **Incorrect drive rolls:** Ensure the wire diameter matches the stamping on the drive rolls. Replace if necessary. * **Incorrect drive roll pressure:** Adjust the pressure screw clockwise until the wire feeds without slipping. * **Worn or dirty drive rolls:** Clean or replace the drive rolls. * **Incorrect wire spool friction:** Adjust the friction nut on the spool shaft for proper wire tension. * **Worn or dirty outlet liner:** Clean or replace the liner. * **Rusty or dirty wire:** Replace the wire. * **Partially arced, melted, or improper size contact tip:** Replace the contact tip.

Why does my Tweco Spool gun have a variable arc?

  A variable arc in your Tweco Soldering Gun can be caused by a worn or incorrect size contact tip, so try replacing it. Another potential cause is incorrect wire feed speed. Adjust the wire speed by turning the speed control knob clockwise to increase the speed or counter-clockwise to decrease it.
