Any welders or metal hobbyists here?
I am a 20 + year welding and metals teacher and welding inspector. I also have a website www.weldguru.com. I always enjoy talking anything metals related be it it fabrication or art as well. Any other metalheads out there?

http://www.weldguru.com/110-volt-mig-welders.html Be cautious of "flux core" wire for thin materials. I will be honest harbor freight or northerntool migs are quite useful as long as you watch the duty cycle. Personally if I were looking for a sheet metal machine on the cheap I would by a cheap one WITH gas input and get a bottle of 75/25 AR/CO2 mix and learn to be a really good spot welder . Use .023 solid core wire. You will be amazed what you can do.

Welder buddy is like that too. I'm just glad I've got someone like him on hand to teach me. My welds used to look like a mud daubers nest but he has straightened most of that out for me.

http://www.weldguru.com/flux-core.html Long story short - be sure you are runing it DCEN if it is gassless wire (electrode on negative) - Use a long stickout (3/4 to 1 inch between end of contact tip and metal) this preheats the core - You do not need the nozzle with gassless flux. - use side to side (weaving) motion do NOT back up and weld over the slag - voltage = weld width - wire speed = penetration + filler this is true on all wire welders

http://www.northerntool.com/shop/too...5145_200485145 Interesting, I have been eyeing those power sources, would love input from a welder on them. Have you tried the spool gun on alum yet? We have several different alum wire setups, a major learning curve there ! All setup.
