The ampere rating of wire would depend on the diameter, length and usage of wire for specific purpose. Without additional input to the question. it will be hard to give an accurate answer.

#6 You can use number 6 copper if you wish,you will definitely not overload it or you can figure the wire size by the duty cycle. If your welder has a 100 duty cycle rating use wire good for 52 amps or a number 6. If the duty cycle is 90, multiply the amp draw by .95 x 52 or 49.4 amps or a number 8 wire. These are a few more of the duty cycle multipliers 80 duty cycle(.89) 70 duty cycle(.84) 60 duty cycle(.78)Duty cycle takes in to account that most welders do not weld continously at maximum welder output all the time.
The larger in diameter the wire is, the larger the current carrying capacity the wire has.

A #4 aluminium wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively.

The Inverter is a sort of Backwards device.Let's say if you wire up a button to an Inverter and the Inverter is wired up to a Wiring door. When the Button is turned off, the door will open. When the button is turned on, the door will close.
You put it togather. If the lighter outlet is rated at 120 watts [that's 10 amps at 12 volts] maximum, then that means that the receptacle, wiring to it, and the fuse cannot carry a 300 watt [25 amps at 12 volts] load, AND SIMPLY PLUGGING IT IN, as suggested in answer 1 should result in blowing the fuse for that circuit. Do NOT let anyone talk you into replacing the 10A fuse with a 25A fuse, as that is a guarantee for burning up your wiring, and possibly your car. However, you do not mention whether the 300 watt rating for the inverter is the OUTPUT or INPUT RATING. IF, and ONLY IF, when you check the INPUT wattage rating [should be on a label or stamped into the outer cover of the inverter], if it indicates an INPUT rating of 120 watts [10 amps at 12 volts] or less, then you can just "plug it in." If the inverter input current rating exceeds 10 amps at 12 volts, then it will not work. To provide adequate power for your inverter, it would be necessary to add-on a new circuit from the battery, or the main fuse panel, with properly sized wire[s] for the load, a proprly sized fuse to protect the wire[s], and a socket also properly rated for the electrical load.j3h.
