4. Connect the copper interface to your machine’s mating connector and verify secure electrical contact.
5. Set wire feed speed to a low starting value and perform a test feed to check for smooth motion and no birdnesting.
6. Increase wire feed speed to match your welding parameters and perform a short tack or bead to confirm proper feeding under weld conditions.

Tips for smooth feeding

If you spend a little time dialing in the setup, you’ll avoid common feeding headaches and get better welds. Small adjustments to tension and groove selection can make a big difference.

• Use the correct groove wheel (V for solid wires, K often for flux core depending on wire profile) to prevent slippage.
• Keep the feed tube straight and free from kinks; smoother paths reduce drag.
• Adjust tension enough to prevent slipping but not so tight that it deforms the wire.
• Start at lower feed speeds and trim rates before moving to production speeds.

Maintenance and care

Treating the feeder well will extend its service life and keep performance consistent over many months of use. Regular checks and a few simple cleaning steps prevent the most common issues.

• Clean the drive wheel and gear surfaces periodically to remove dust, flux, and metal particles.
