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.

Some electrodes (welding rods) can be used AC or DC. Some are strictly DC. You may find that most electrodes run smoother on DC. Most industries purchase machines with DC capability.

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.
A welding rectifier is a m/c which converts A.C. supply to D.C.supply. Rectifiers are used for heavy welding work. An invertor is a welding m/c which converts A.C. supply to D.C.supply and then again converts D.C. to A.C. The wt. of invertor welding m/c is less than a welding transformer.
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.

Can be either, or even selectable.
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.

Both are shielded metal welders but differ in the electricity they use. Ac welders can weld heavier metal while dc welders are better for thinner metals. Ac welders can weld magnetized metals. Dc welders can not. The arc in an ac welder is harder to control because of the pulsating current. Dc welders are more expensive. Some welding machines offer both options.
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
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.

Well, first of all it's entirely possible to weld with ac as well. But if you want dc it's usually accomplished with diodes in something called a bridge rectifier.
A dc is an acronym for direct current & 2 be put in to use,changed to ac which could then be used in welding
DC WELDING:We gain a smoother welding because of constant and linear direction of current.The arc will be more stable and easier to handle.DC welder can use both AC and DC welding rods.AC WELDING:The arc is not stable here and needs to be stuck again because of the fluctuating nature of AC.It is not as smooch as DC welding.These welders cost less when compared to DC welders.
