Arc Welding is The Most Recognized Welding Process Throughout the World

By Peter Smith

If you are using an arc welder you are not alone as that welding process is being used right around the world. You can see an arc welder in virtually any workshop or farm shed. Manual metal arc welding is also know as stick or arc welding, this is how we commonly reffer to it.

Don't go around saying that you are manual metal arc welding or using MMAW. You will come across as a bit of a weirdo, and people will think you are missing something. Just call it either stick or arc welding nothing else.

The arc welder is basically a big power transformer. Power goes in at one end, this end has a higher voltage and then it comes out the other end at a lower voltage. Usually it will transform you street power from 415v, 240v, 220, or 110v down to a stable welding voltage.

The majority of arc welding machines in the world use a DC welding output. This originally was an AC waveform that has now been converted and transformed via the "transformer" into the DC source. This is now a lower voltage source of power that does not change polarity, making it great for welding with.

You can actually weld using two car batteries buy hooking them together. If you add the two together you will get 24volts and the raw amps that a single car battery can put out is huge. Now you have two of them and you can actually weld with this.

As most people who go four wheel driving quite often have a dual battery setup, all you need to do is make sure you have a set of thick jumper leads and a pack of welding electrodes in the back. This way you can do emergency break down repairs. A good rod to use is either a E6012 or E6013 in probably 2.0mm diameter size.

Any smart traveler will have a set of jumper leads in the back of the vehicle. So all you have to do is join the two batteries together using some existing wiring from the vehicle. This is done by joining the positive terminal of one battery to the negative terminal of the other battery.

Then simply clamp the jumper leads to the now larger 24volt battery, and you have a quick and simple arc welding machine that you can use to make roadside repairs in the middle of nowhere.

Yes arc welding is easy but you must learn how to arc weld right the first time. - 21396
