Re: New welder with quick question

Being technical here, to my knowledge there is no such thing as "gasless" wire. When the term is used describing self-shield as gasless, it is not correct. To quote the link provided earlier "As their name implies, gas-shielded flux-cored wires require an external shielding gas suppl...

Re: New welder with quick question

Here's a link to what looks like a good explanation of FC wire types. http://www.thefabricator.com/article/arcwelding/start-with-the-basics-understanding-flux-cored-wires Since you'll be working without shielding gas, you can avoid the wire types that require gas... so it seems like then your choic...

Re: New welder with quick question

OK... I think I found an answer to the wire size question... The heavier wire will carry more current which will affect the welding capability (this makes perfect sense). But .035 may be pushing the limit on my 140 amp welder. I think I should stick to the .030 wire size correct?

Re: New welder with quick question

Hey, With the wire classification, the 70 refers to the tensile strength of the weld metal, and the last letter, in Aus, an M or a C. It is m for mixed gas (argon based) and C is for pure carbon dioxide. Mick Thanks Mick, Yes I think I understand the coding system. I'm just not sure which wire to b...

New welder with quick question

I just bought my first ever welder and need some advice on buying consumables. I don't have gas (yet) so I'm going to start with flux core wire. Been researching on the internet and am completely overwhelmed with the selections available. I will probably be doing general welding (repair and fabricat...
