noob here that ain't so new. i just joined to learn again. i'm not a certified welder. just certified retired. best friend back in the 70's and his family owned a sawmill. i taught myself to weld while working there on an airco gas and will say i got pretty dang good at it. problem though is that was 40-45 yrs. ago. now i wear bifocals because i can't see but i'm practicing with a titanium 125 flux from ahem...cough...harbor freight. it's actually it seems a decent rig. i've been welding 2x2x1/8 and it looks sick but you can't break apart. just picking up tips and helping out if i can.
