I'm using a HH175, flux core and the helmet in the Weldit package(dark green lens) . I'm having a devil of a time seeing the wire melt. Tried different positions, dragging, a strong back light close to the work and its not too often that I can see whats happening. Will solid wire make a noticeable improvement? Disclosure: I'm over 50 and the eyes ain't what they used to be. But still, anything I can do to see the action better? How close is your face to the work?
