30amp v. 50amp
Lots of good advice. What amp plugs did you go with? 30 or 50 amp?
I assume you're referring to individual outlet capacity. Really depends on your workflow.
For 120v outlets, I am fine with 30amp. Most benchtop and portable tools are anywhere from 7-20amps individually. I sometimes use a power strip to get an extra outlet for a shopfan, which can push the limit, but I'm typically below 30amps.
If you can, 50amps is better. Then you'll never have to worry about motors bogging down before the breaker trips (which can allegedly cause motor damage, but never has for me). If I'm cutting thick lumber on my table saw, running a fan, and a dust extraction off one outlet, that'll happen.
For 220v outlets, I'd definitely lean toward the 50amp or higher capacity. 220v machines I'm interested in buying draw 30amps individually. If you don't need 220v machines in the near future, just make sure you build the shop in a way that'll easily facilitate a 220v upgrade. Welding
If the Hobart works well for you, keep with it till you have a reason to upgrade. Maybe get a Lincoln 4c shielded mask as your first upgrade, then a new welder when it's time.
One reason MIG + flux core is cool is you never have to worry about refilling gas tanks. MIG + bottled shielding gas is supposed to reduce spatter a little bit, but then you've gotta buy more equipment and be mindful of gas usage. Welding and Woodworking Air Extraction
Make sure you're responsible with sawdust collection. Sawdust is extremely combustible. Don't ever let the welding get near the wood and sawdust. And keep a fire extinguisher on site, just in case.
Welding and woodworking should have separate air extraction systems. That way welding fumes don't ruin the filters on your dust extractor, and you don't have to worry about molten spatter starting a fire in the ducts. Downdraft table, PAPR airshield helmet, ventilation hood that blows air outside - all viable solutions. Maybe even just a shop fan with a flexible duct (i.e. Fans | Blower Fans | Flame Retardant Flexible Duct 32 Ft. for 12 Inch Diameter Fan | 246345 - GlobalIndustrial.com
) would do it.
Feel free to ask anything else!
