The longer you strech the arc, the smaller the voltage. Current rises though.

What is arc voltage or arc length?
It just means length.
How do you find the length of an arc in geometry?
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
Does the arc length equals the measure of the arc?
No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
What is the difference between arc measure and arc length?
Arc measure is the number of radians. Two similar arcs could have the same arc measure. Arc length is particular to the individual arc. One must consider the radius of the arc in question then multiply the arc measure (in radians) times the radius to get the length.
What is the arc length if the length of the arc is 95 degrees?
Find the circumference of the whole circle and then multiply that length by 95/360.
What is arc voltage or arc length?
It just means length.
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. -
The length of arc AB is 28.61 What is the length of arc ACB?
The length of arc ACB is 57.2.
What is an arc voltage in a circuit breaker?
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
Arc length equals the measure of the arc?
The arc length is the radius times the arc degree in radians
Which welding process uses a constant current power source?
smaw and tig(gtaw) are using CC source. because these both types using manual wire feeding. so welder can not able to maintain constant arc length. change in arc length will change voltage. so it needs power supply which should not affected by this arc length = voltage changes. that's why CC type is used for these process. in CC type source change in voltage will not change current much.
Who to arc length Radius of the circle 4756 and angle 45deg find arc length?
(arc length)/circumference=(measure of central angle)/(360 degrees) (arc length)/(2pi*4756)=(45 degrees)/(360 degrees) (arc length)/(9512pi)=45/360 (arc length)=(9512pi)/8 (arc length)=1189pi, which is approximately 3735.3536651
How does arc length affect a weld?
Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.
What is the arc length of the minor arc of 95 and 18.84?
find the arc length of minor arc 95 c= 18.84
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 controls the maximum gap the electrons can jump to form the arc?
The distance between the electrode and work and the type of atmosphere surrounding the arc. Voltage pushes the current across the gap and the longer the arc length the higher the voltage has to be. In the TIG (GTAW) process Helium is lighter than Argon which allows less resistance to the arc allowing it to jump greater distances. Both have limitations as to how far the arc will travel across a gap.
How do you find the length of an arc in geometry?
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
