Forney 42300 Flux Core Mig Wire, Mild Steel E71TGS.030-Diameter, 2-Pound Spool, Silver, Pack of 1

Forney 42300 Flux Core Mig Wire, Mild Steel E71TGS.030-Diameter, 2-Pound Spool, Silver, Pack of 1

Q: Will this work with a cheap 90 amp harbor freight

It works better than the wire that came with my HF welder. I did upgrade the wire feeder with one I found on Amazon. Also, I am using a 0.030 tip instead of the 0.035 that came with the machine. Machine is 8 years old and runs better now than when it was new.

Q: can I use this with my 125 amp flux core welder from harbor freight

Danny, This wire would be perfect to run in your flux core welding machine! Thank you for your question.

Q: can I use this to solder?

By solder you mean electronics? Like motherboards and so? You dont need shade for that but i am sure you can use an auto darkening helmet since it is clear it will stay that way

Q: What is the diameter of the center hole.

I believe .030/.8mm and .035/.9mm
