I read that it can go up to 80 Volts, any more and it becomes a shock hazard to the operator.

What component of a welding machine changes AC current to DC current?
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
Can you use home generator to power arc welding machine?
As long as it is rated for wattage output for required voltage for welding machine
Difference between two phase and three phase welding machine?
Three phase uses a safety circuit away from the machine, two phases uses you as the safety circuit
Who invented the first welding machine?
Advani company was manufactured the first welding machine
What is a welding transformer?
A welding transformer is an electrical transformer used in welding power supply. It pulls relatively low current drawn from the mains power (typically limited to 15 A to avoid tripping the circuit breaker) and converts it to the typical 50 A to 500 A used in arc welding and higher currents used in spot welding. The main difference between a Normal Step Down Transformer & a Welding transformer , is Not only to Step Down ( lower ) the outlet supply voltage and at the same time increase the Available Output Circuit Current, but to be also able withstand the Short Circuit Conditions on the Welding Output Side and especially for the Magnetic ( Iron Lamination Core ) Part of the Transformer. This Magnetic Path difference prevents the Supply side Electrical Circuit from Oveloading , espcially during the Striking of the Arc, when the Welding Electrode & the Welding Job touch to initiate an Arc, after which the Welding Electrode is lifted slightly by Experience, to maintain the required weld flow. A Normal Transformer of equivalent rating will not be able witstand this operation without burning out.

What is ocv with MMA welding?
Open Circuit Voltage
How do you set up a welding rectifier?
A rectifier is a type of welding machine. Fairly new development that changes common electrical supplies to voltage and amperage that can be used to weld. It uses less electricity than standard welding machines (usually transformers). It will require a certain supply (voltage - amperage) that you connect the machine to and should state the minimum requirements somewhere on the machine.
Why do we need a transformer if we use a welding machine?
A welder requires high current at the expense of voltage, The transformer reduces the voltage allowing a higher current to operate the welsing machine.
What type of welding machine does not have positive and negative terminal connection?
Transformer type welding machine
Difference between two phase and three phase welding machine?
Three phase uses a safety circuit away from the machine, two phases uses you as the safety circuit
What is the higher voltage at the electrode before the arc is struck called what is it's advantages to welding?
Open circuit voltage is the voltage at the electrode before striking an arc (with no current being drawn). The higher the open circuit voltage, the easier it is to strike an arc because of the initial higher voltage pressure.
What is the power rating of 500 amperes welding machine?
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.
How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
What size wire feeder should be used for 300 amps welding 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.
