Flux core wire?

RRR I have had a few hoods in my time... Miller, Jackson and Speed Glass(now 3M) I just replaced me original Speed Glass with the above mentioned hood after better than 20 years of service with only replacing the head gear once and the batteries several times. IMHO the Speed Glass is the best hood on the market. I hope this one will serve me as long as the last one and should in all possibilities be the last hood I purchase in my life. Nothing wrong with Miller or any of the above mentioned hoods but this is just my preference.
