2014/3/25· We use .030 on occasion and as a general rule and per specs 150 amps should be the max you want to use for that wire. On the .023 I would have to say do not exceed 100 amps+/-. Your wire feed speed will be a lot higher with the smaller wire thus you will burn the spool out faster.
Welding - Wikipedia
Welding is a fabriion process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
How to TIG Weld With Flux Core Wire – Welding …
FCAW, Flux Cored Arc Welding, the higher-level term for TIG flux core welding, is commonly used when the strength and advantages of flux core wire outweigh the additional costs. Above I already listed frequently added micro-alloy elements, slag building chemicals, gas building elements, and additives that are blended in the powder.
All You Need To Know About Flux Core Welding | WelderIT
When working with thick materials, flux core welding guarantees a good and strong weld with a single pass. The FCAW is recommended for outdoor use due to the shielding gas produced by the wire. Welders feel that FCAW is convenient for them because they
