Default Re: Welding newbie need advice

A mig is constant voltage. The wire speed is the current.

In MIG welding amps are adjusted by changing wire speed. The higher the wire speed the more amps.

For thinner metal you would want to slow the wire speed down and adjust the voltage.

If the voltage is too low the wire will hit the puddle. If the voltage is too high the arc will be too big and there will be lots of spatter.
