A number of years ago I bought a Lincoln P-135 + Mig welder and use it for mainly ornamental items. As I am not a pro my number one rule is to never stand under anything I have welded. I don't weld anything that is life safety related. I may tack something together to have it later properly welded by a pro.
I have good results with thinner mild steel, sheet metal etc running mig mode but when I try flux core on heavier steel 1/8" or so I have concerns. I run Lincoln Innershield .035 NR-211-MP wire and find it brittle when I do destructive testing of my welds. The weld looks OK but when bent the weld bead breaks while the base metal bends.
The bead also wrecks my cold cut blades, I assume from hardness.
Is this normal? Any suggestions?
