Ooh! Ooh! I know, welding, cutting, grinding maybe even metal work/forming?
What are you asking or looking for?
Most good shops will have many options, some may even have machining capabilities.
All depends we manufacturer and in the shop we use a miller 252 it does aluminum stainless flux price is about 4 grand if i remember rite but its only 60% duty cycle in the field we use a miller bobcat. flux is your strongest weld i believe but mig is your most used in the manufacturing sector at least our part but im sure some have different opinions
