What is cheaper to buy ac or dc welder?
A dc welder is a lot cheaper by fair of the two
What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
How does a welder know what electrode he is using?
Almost all electrodes have a series of numbers to tell #1 what the tensile strength of the weld will be, #2 what electrical current to use, #3 what position/s it can be used in (ie: flat, vertical etc.) Ex. E - 7018. E = electrode, 70 = 70,000 lbs tensile strength, 1 = all positions, 18 = AC or DC reverse polarity current. (welding lead +)
When welding with DCEN the electrode is positive and the work is negative?
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
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.
When welding with 7018 rod is the electrode holder positive and the ground negative?
Yes, the electrode holder (stinger) is positive and the ground is negative which means you would be welding DC positive.
Explain welder polarity?
Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.
What is cheaper to buy ac or dc welder?
A dc welder is a lot cheaper by fair of the two
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
What is meant by anode and cathode?
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
Why is the positive electrode used up in electrolysis?
Thise electrode is the cathode.
What do you call a negative electrode?
Cathode- is the negative electrode.Anode- is the positive electrode.
If zinc electrode is dipped in zinc sulphate the electrode will become positive or negative?
if it is dipped the zinc electrode looses the electron in to the solution as zinc ions and it attains negative charge on th electrode and it absorb the positive ions in the solution.so w can see a bundle of positive ions just around the zinc electrode
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
How is electrolysis of water used?
Electrolysis, passing an electric current, through water separates the water into its elements: oxygen and hydrogen. When Direct Current (DC) is used, oxygen precipitates (comes out of) the water at the positive electrode and hydrogen precipitates at the negative electrode.
In a wet cell electrons move from the negative electrode to the positive electrode?
A wet cell refers to a primary electric cell wherein the electrolyte is a liquid. It is true that in a wet cell, electrons move from the negative electrode to the positive electrode.
