Never. I've seen reviews saying is excellent and others disagreeing. I guess its among the better wires.Have you ever used the HF shielded wire? Adequate?
My favorite is INETUB BA71TGS .030.
This is from an Italian company specializing in quality welding products, so its definitely better than any bargain wire.
I've seen posts guessing Harbor Freight's wire is re-labelled INE wire - not verified.
I see it's expensive at the moment. I paid 25% less, recently.
Camelcamelcamel, a price tracker for anything on Amazon,
shows price history and can email you a notice next time its on sale.
Definitely start with quality wire until you have some experience, to reduce the number of variables you have to figure out!
