the only way you can weld aluminum is with AC current and high freak setting on the welder , if your welder does not have theses setting then it will not weld aluminum. Good answer! AC is a must! The only other way is if you have an oxy/ace setup (very low psi) or alot of mapp gas, but you have to spread a flux paste on the material (looks like drywall mud) EXTREMELY MESSY!
Check the nameplate on the welder, if the voltage that runs the welder is 240 volts then the two black wires connect to a 240 volt supply and the green wire connects to the ground of the supply.
The size of the circuit breaker and the wire that will feed the welder is based on the amperage that is needed by the welder. The voltage only explains what the insulation factor of the wire should be.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
6010 penetrates deeper than 7018 does. It is a "fast freeze" rod - the puddle solidifies quickly. There's not much slag and it chips off easily. It also requires DC electrode-positive polarity. If you have an AC-only welder like a Lincoln AC-225, get 6011 which is almost the same rod but it will run on either AC or DC. Most guys who use 6010-series rods are welding pipe. Guys who weld bridge decking grab this rod first because of its penetration. 7018 is a rod with low-hydrogen flux. It produces a LOT prettier weld than the 6000-series rods do, but it's got to be stored in a rod oven because moisture in the air changes the way it welds. These are generally used for structural welding. These are two of the most general-purpose rods out there.
The meter should be on the AC scale. In Canada and US the reading should be 240 on the outside blade holes and 120 volt from the outside blade holes to the center blade hole. The U shaped pin is the ground. No voltage from it to the center pin.
Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.
A dc welder is a lot cheaper by fair of the two
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.
There are several tools which are used by welders. Some tools include a cutting torch, helmet, AC Arc welder, and metal cutting tools.
A dc is an acronym for direct current & 2 be put in to use,changed to ac which could then be used in welding

It produces alternating current AC. It is cheaper to build than a DC or an AC - DC welder. Most electrodes can be used with DC. Some can be used for both. Very few are AC only. DC produces a smoother arc, is easier to strike an arc and most machines in industry are DC. Surprisingly a lot of AC machines are on farms as they were cheaper to buy.
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.
For output, either one. Most machines produce Direct Current DC. It is much easier to use and most electrodes can be used with DC. Almost all use Alternating Current AC for a power source - input. Hope this helps.
That would depend on the model , age and condition or hours .

You probably mean "... where there should be a DC output ?",and the answer is "No. They don't work in reverse.".
