How do you calculate arc length between electrode and charge in arc furnace?

Arc Length depends on the secondary voltage of furnace transformer. Thumb rule is for 500V the Arc length would be 500mm(20"). The purpose of arc length is to give maximum power to the melt, without arc flare. -

Is Welding set a high voltage or high current load?

The arc utilized for arc welding is low voltage high current discharge. The voltage required for maintaining an arc is less than for striking the arc. Voltage drops & current increases as the arc is developed. The voltage required to strike DC arc is about 50-55 V & for AC is 80-90 V.It is difficult to maintain the arc with voltage less than 14V or more than 40V.READ ELECTRICAL TECHNOLOGY BY B L THAREJA / AK THAREJA

What is the proper ampere rating of circuit breaker for electric arc welder?

The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.

How is an arctangent a crater creator?

In a crater, the slope of the side of the crater is simply the arc-tangent of the height difference divided by the horizontal distance.

If a lunar crater has a diameter of 1 minute of arc what is that in kilometers?

The diameter of a lunar crater with 1 minute of arc is roughly 1.6 kilometers. The actual size of lunar craters can vary widely, so this is just an approximate value.

Can the unaided eye resolve a crater on the moon whose angular diameter is 1 arc minute times 60 arc seconds. Take the pupil diameter to be 5 millimeters and the wavelength........?

I can resolve 100 arc seconds. If craters are 60 arc seconds I'd bet that there are people whose eyes are good enough. 60 arc seconds is certainly within the 20 arc second maximum capability of the eye.

What is end return in a weld?

Not exactly sure what you're asking but this may be the info you want. When stick (SMAW) welding as you progress with the bead directly under the arc a slight depression forms. Called a crater. When you get to the end of the bead if you pull the electrode away the crater is there which promotes crater cracks. By pausing at that point and actually backing up a little the crater is filled. With practice the weld is the same height and width all the way to the end. Hope this is what you are asking about.
