A 220v welder will take about half the amperage of a similar 110v welder. **90-100 amps** is fairly common, but you can find smaller (and larger) welders. An air compressor will probably take a lot less current, maybe 20-30 amps for 220v or 20-50 amps for 110v.

Also, How do I calculate wire size?

Divide the voltage running through the **cable** by your target current. If, for instance, 120 volts will act on the **cable**, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. Multiply the **cable’s length** by its material’s resistivity.

In this way, How many amps does a 240 volt welder draw? For small **welders** that run on 115 **volts** can produce up to 140 **amps** and will **weld** up to 1/4″ thick steel. For 220 **volt welders**, you can expect around 200 **amps** and **weld** up to 1/2″ material. Of course, this depends on the **MIG welder** you have and what you **weld** with it.
