welder question-what to buy? Options

[rfuerst911sc]

Now that I have dug into my 914 project I'm going to have to do some sheet metal repair on the rear trunk floor. Also in the future will be various chassis reinforcements being added and possibly flares for the wheelwells. I have a oxy/acetylene along with a old 300 amp stick welder but I'm thinking a mig welder is what I want? Today I looked at Lowes,Home Depot and Tractor Supply at Lincoln and Hobart 140 amp migs that run 110v. So can I do this work with my oxy/acet unit or should I go mig? And if I go mig any preference to brand? I know that shielding gas is preferred over flux wire.Help me out guys. Thanks

I've been thinking about buying one of these Millermatic 175's . Does anyone know if you can buy an electrical cord (say 20 feet long) that you can plug into the electrical outlet for a dryer to run a 220V welder?

Ditto on the custom extension cord.
I went to Home Depot and picked up 25' of their heaviest gauge multi strand wire/cable and 2 A/C plugs. One male for the dryer outlet and one female for my welder. They have a few different types of plugs so make sure you get the right ones.

Remember:
Wire of a certain gauge is rated in ohms/ft. 6g wire is rated at 0.00048 ohms/ft. Remember V=IR, so V = 100 * 0.00048, or V = 0.048v. This is the amount of voltage "lost" due to the resistance, or the "voltage drop". The rule of thumb is the voltage drop should be no more than 2% of the original voltage
