Another Mopar Off My Bucket List - Barracuda Fastback

Seriously,it happens 66..... I had a shopmate,who ran an 80 foot 110 extension cord combination,to wire wheel an Ford Maverick front suspension for clean up. They cables weren't even touchable... I told him to plug into his brother's 110 outlet,or I was going to raise his rent. Yes,it can happen....

I'm not trying to start an argument here but if you get an extension cord with an adequate amperage rating, you should be fine. If the cross-section area of the copper is large enough, the losses can be kept at a safe level. Use the shortest cable possible, too. It's probably best to only have have AWG 12 extension cords in the shop. Or maybe even AWG 10. They are pretty beefy, though ...
The duty cycle is important, too. If you're running an angle grinder, you're running it continuously. The welder prbably doesn't see more than 20-50% duty cycle.
Here's a good guide I found:
