Best Answer

Alternating current flows from the welder through the torch into your welder, through the grounding cable, and back into your machine. It then flows in the exact opposite direction. The result is deep penetration, and removal of impurities in the weld. It is used mainly on aluminum and alloys. Direct current has both a positive and negative setting: the difference is the direction of the current. One flows from the welder, through the torch, through the material and back into the ground; the other flows in the opposite direction.

What component of a welding machine changes AC current to DC current?

Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.


How AC is converted into DC in welding machine?

rectifyer


When to use dc welding machine and ac welding machine?

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.


Normal welding machine out put DC or AC?

Can be either, or even selectable.


What is the difference in welding rods for ac welders and dc welders?

The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.


What is the difference between ac arc and dc arc welding?

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.


What type of welding can you do with an ac welding machine?

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


Can you use Stick Welding machine for Spot Welding if yes how?

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.


How it is convert from ac to dc in normal welding machine?

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.


I have a chicago electric 180 acdc arc welder can i use the same welding rod for either ac or dc welding?

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.


What is the difference between ac and dc grounding?

The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.


What is the difference between AC and DC choke?

There is no difference between AC AND DC chockes
