Re: Best portable engine drive welder

I like 6010 5P+ the best for this type of application. Better toughness and ductility.
Not according to Lincoln, and my hunch is that their engineers and metallurgists know better than anyone here.

From Lincoln spec sheets:

7018
Elongation: 25-37%
Charpy V-Notch: 121-332 J at -20°F

6010
Elongation: 22-29%
Charpy V-Notch: 51-93 J at -20°F

A pretty big difference, with 7018 being FAR more ductile/"tough."
