Frequently Asked Questions
Can I use flux core wire with my MIG welder?
Yes, most MIG welders can accommodate flux core wire. Ensure your welder is set up for flux-cored welding, which typically involves switching the polarity to DCEN (Direct Current Electrode Negative).
What materials can I weld with flux core wire?
Flux core wire is commonly used for welding mild steel and galvanized steel. It's suitable for various applications, including structural work, fabrication, and repair tasks.
Do I need to remove slag after welding with flux core wire?
Yes, flux core welding produces a slag covering over the weld bead that should be removed after welding to inspect the weld and prepare the surface for any subsequent coatings or treatments.
