Frequent Flux-Core Issues

🔥Flux-Core Troubleshooting Guide

📋 Problem: Excessive Spatter

• Is polarity correct?

🔧 Fix: 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.

📋 Problem: Inconsistent Bead

• Are you maintaining a correct consistent gun angle along the joint?
• Is your travel speed consistent and steady?
• Are your settings hot enough?

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