What is current adjusting wheel of an welding machine?
Regulating the medium of welding according to the needs
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
What is a typical open circuit voltage for an arc welding machine?
I read that it can go up to 80 Volts, any more and it becomes a shock hazard to the operator.
Who invented the first welding machine?
Advani company was manufactured the first welding machine
Why thyristor used in resistance welding machine?
For firing current between the the moving arm of the gun and the fixed arm
What is typical open circuit voltage for an arc welding machine?
voltage available to the welding current via the machine
What is current adjusting wheel of an welding machine?

Do I need regular oil changes on an oil cooled welding machine?
no
What is AC welding machine?
An AC welding machine is one that uses electrical power from house or shop and has a controlled output in AC or Alternating Current.
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
What type of welding machine does not have positive and negative terminal connection?
Transformer type welding machine

What is a welding lead?
the welding lead is the cable coming from the welding machine that either feeds the wire and shielding gas (mig) or or provides current to the electrode through the holder
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.
