I'm using rackmount Olympia b flux core .045 wire with millermatic 211 and using co2 so its duel shielded. I am noticing quite a bit of cracking in the welds and I'm pre heating the excavator bucket like recommended to 420 degrees f. not exceeding 450 degrees f. and using a heat gun and torch to control the cool down. I'm assuming this is normal for 65rc rating, since I test the welds and they will chip off parts of my chipping hammer and not the welds. just looking for opinion's on this product and advice on better techniques/use of this product.
