Frequent Flux-Core Issues

🔥Flux-Core Troubleshooting Guide

📋 Problem: Excessive Spatter

• Is the voltage too high?
• Stick out too far?
• Is polarity correct?

🔧 Fix: Lower voltage slightly, shorten arc length, make sure leads are hooked up right (DCEN - ground on positive and electrode negative. This is opposite from MIG solid wire welding so make sure to do this when running flux-core wire).

📋 Problem: Burn-Through

• Are your settings too hot?
• Is travel speed too slow?

🔧 Fix: Turn down settings, move steadily, avoid stopping in one spot.

📋 Problem: Inconsistent Bead

• Are you maintaining a consistent pull angle?
• Is your travel speed consistent and steady?
• Are your settings hot enough?

🔧 Fix: Keep a consistent pull angle, make sure travel speed is steady and consistent, try cranking up the settings to run hotter so puddle is more fluid and fuses into material better.
