An AC welding machine is one that uses electrical power from house or shop and has a controlled output in AC or Alternating Current.

Dc welding can be used for non consumable electrodes with consumable electrode heat is transferred from electrode to work by molten metal. Ac welding is desirable for aluminum and magnesium, because it helps break up oxides AC is more stable than Dc.
Transformer type welding machine
In a welding machine, the rectifier is responsible for converting AC into DC. AC current fluctuates, but DC provides a steady flow, making welding smoother and easier to control. Many welders prefer DC for its stable arc and reduced spatter, which leads to cleaner welds. Some machines even offer both AC and DC options, allowing welders to choose based on the material and type of welding they need to perform.
Usually the rating of a welding machine is expressed on the DC output side. What you need to state is what the input in voltage and amperage is. It is this side of the welder that is connected to the supply breaker. On the nameplate there will be a voltage, amperage both stated for an AC supply connection.
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.

Yes it is available
Can be either, or even selectable.
6010 is intended for DC welding. It has no additives in the covering to keep the arc going each time the AC voltage reverses, so it is very hard to keep the arc struck. The result is usually poor quality welds. The solution is to switch to a rod designed for AC, such as 6013.
You can do Shielded Metal Arc Welding (stick) with an appropriate electrode. If the machine has a high frequency arc stabilizer then you can also TIG (tungsten inert gas) weld aluminum. Wire feed processes require a DC machine
Transformer type welding machine
They sell a spot welding gun that plugs into a DC arc welder. If you have an AC225 or some other AC-only machine, this won't work. In general, tho, spot welders have their own power supplies so you don't need to reconfigure your stick welding machine for this.
