we will have straight polarity and reverse polarity,we can produce the weld with good quality

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.
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.
Why Dc welding sets are prefered over AC welding sets?
Often because with DC, it is possible to change the direction of the weld current for the task at hand.
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
What is the effect of AC and DC in arc 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.
The majority of SMAW welding is done using what two polarities?
DC-
What are the three types of machines used in manual metal arc welding?
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
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.
Normal welding machine out put DC or AC?
Can be either, or even selectable.
Which type of welding is preffered ac arc welding or dc arc welding and why?
Both currents have their ups and downs but both are used in the maufacturing industry, in reality it depends on your base metal and electrode.
Can a DC motor be turned into a welder?
A dc is an acronym for direct current & 2 be put in to use,changed to ac which could then be used in welding
