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.
Welding is done with a high current and low voltage. The voltage of a 500 amp welder might be 10 v so the power rating in that case would be 5000 watts.
A welder requires high current at the expense of voltage, The transformer reduces the voltage allowing a higher current to operate the welsing machine.
Usually the rating of a welding machine is expressed on the DC output side. What you need to state is what the input in voltage and amperage is. It is this side of the welder that is connected to the supply breaker. On the nameplate there will be a voltage, amperage both stated for an AC supply connection.
Both use electrical current to melt the base metal and the filler metal. Both could be considered ARC welding. Most welding is done with an electrode (stick) and as the electrode becomes consumed the weldor has to stop and replace it with a new one. MIG welding uses a spool of wire and can be run for hours on end. MIG is usually easier to learn.
Yes it can. I use flux core wire because there is no need for gas with flux wire.
the basic principle of welding is 1. first we have some broken material 2. a welder 3. welder should know how to weld
The type of welder is dependant on what you want to weld with the machine. Welding heavy steel will take a bigger machine than one that is used for light metal.
The other welder will also fail.
In the United States, the three top welding schools that prepare students for structural welder and master welder certification are: Tulsa Welding School (in Tulsa, OK and Jacksonville, FL), Hobart Institute of Welding Technology (in Troy, OH), and Lincoln Electric Welding School (in Cleveland, OH). Completion of these programs will provide qualifications for more advanced (greater than entry level) welding jobs.
There are a few places online such as Welding Web, Grainger as well as Lincoln Electric offer websites that someone looking to purchase a Pressure Gauge for a welder can be purchased.
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.
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
they moved their location somewhere and the welder is quite valuable i believe.
Graduating from a welding school can open up various job opportunities in the welding industry. Welders are in demand across sectors such as manufacturing, construction, oil and gas, automotive, aerospace, and more. Some potential welding jobs that can pursued after welding school are: 1.Welding Instructor 2.Welding Technician 3.Welder/Fabricator 4.Structural Welder 5.Pipe Welder 6.Welding Inspector
