Pulse MIG with Flux Core Wire

[Vambo]

Hi All

My understanding of using the pulse option on a welder is that it would help with welding thinner sheet metal. However I'm curious to know if anyone has used the pulse option with a self shield flux core wire? If so what parameters and details can you advise on to get a good result.

Cheers, Vambo

Try it and find out? People can give you pages of settings to follow, but every welder is different and what works for one may be too hot/cold for the other...if your travel speed or technique is different that will also have an impact on performance.

Flux core runs best in spray transfer (it makes a hissing sound instead of bacon frying sound).
Pulse mig is effectively pulsed spray transfer, so potentially pulse could work, but standard mig works so well with it that I'm not sure there will be any benefit. Pulse is generally quite hot on most machines. If you try to run FC too cold, whether in pulse or standard, it won't run properly.
Ultimately, if you want a good low amps process, you need solid wire, gas, and short-circuit transfer, which is the bacon frying sound.
