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 +)

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
Is a dc welder electrode positive?
In a DC welder, the polarity can be either direct current electrode positive (DCEP) or direct current electrode negative (DCEN), depending on the desired welding characteristics. DCEP, where the electrode is positive, is commonly used for processes like TIG welding, as it provides better penetration and a hotter arc. Conversely, DCEN is often used for processes like MIG welding, providing a different heat distribution and weld bead profile. The choice of polarity affects the welding process and the type of materials being welded.

How much electricity to run a 140 amp welder?
To calculate the electricity needed to run a 140 amp welder, you first need to know the voltage it operates at. For instance, a common voltage for welders is 230 volts. Using the formula Power (Watts) = Voltage x Current (Amps), a 140 amp welder at 230 volts would require approximately 32,200 watts or 32.2 kilowatts. However, this figure doesn't account for efficiency losses or duty cycles, so it's advisable to consult the welder's specifications for more accurate power requirements.

What does welder do?
Welder as in the person: A welder joins metal together using Oxy-fuel or more commonly Arc processes. Welder as in the Machine: A welder converts electricity from your home/workplace and turns it into suitable voltage and amperage for welding operations. That is to melt the base metal and add filler metal (electrode) In the case of gouging the arc is transferred between the carbon electrode, melts the base metal and a stream of compressed air carries the molten puddle away. A Welding machine may also be a fuel driven machine often used on job sites away from electrical connections.

What does the welder do?
Generally the title of 'fitter' is applied to the person who does the layout, preparation and positioning of parts to be welded. They may also do the cutting of the parts to be assembled and the tacking the parts in place. A 'welder' then comes behind the fitter and welds the parts together. A 'fitter and welder' does the entire job and all the aspects of it.
What is the name of non consumable electrode?
There are no , non -consumable electrodes, there are slower consumed electrodes, as in TIG (tungsten inert gas) welding in which a Tungsten electrode is used , and in the hands of a very skilled welder , last the longest of all electrodes , but are in the end consumed.

Is TIG Welder is also considered as Co2 welder?
No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
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 Rods should i use with an ac welder?
For an AC welder, it is best to use electrodes specifically designed for AC current, such as 6011 or 6013 electrodes. These rods provide good arc stability and smooth welding characteristics when used with an AC welder. Be sure to follow the manufacturer's recommendations for electrode selection based on the thickness and type of metal you are welding.
What does the term single hand welder mean?
A "single hand welder" is any person welding on a job that is not using their own personal equipment. I.E., welding with a company welder or rented welder until you can afford to buy your own welder.
Can you tig with 250 dialarc welder?
Yes, you can TIG weld with a Dialarc 250 welder, as it is capable of delivering the necessary amperage for TIG welding. However, you will need to use a suitable TIG torch and gas setup, as the Dialarc is primarily an arc welder. Ensure you have the appropriate gas supply and tungsten electrode for the materials you are welding. Proper setup and technique will help achieve good results.
How should the values found using the zinc electrode as a standard compare with those based on the standard hydrogen electrode?
Perhaps a rephrasing of the question would help; I've never seen a hydrogen electrode so I don't know how it compares to zinc. The process being done would probably also help (are you electroplating or separating oxygen from hydrogen or ...?), as would the solution the electrodes are immersed in (does the solution react with zinc at room temperature, is it being used in a gas, ...?)
