Flux core wire eliminates the need for gas supply because it has internal shielding properties. Flux core welding is great if the welding is outside and where there might be a breeze as gas won’t blow away. This process is best for welding thicker material with a single pass. 1 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
