Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
A rule of thumb is - the arc length should be the same as the diameter of the electrode. 3/32" electrode = 3/32" arc length. 1/8" electrode = 1/8" arc length etc. The thicker the electrode coating the shorter the distance from the end of the electrode to the work. Drag rods are contact rods. E-7024 is one.

The length of arc ACB is 57.2.
The arc length is the radius times the arc degree in radians
(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
It just means length.
find the arc length of minor arc 95 c= 18.84
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
It is: 72-lenghth of major arc = length of minor arc
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. -
Arc length is the distance from the tip of the electrode to the workpiece.
Arc length = pi*r*theta/180 = 17.76 units of length.
20/360=arc length/2pi*50; 1/12=arc length/100pi. 100pi/12=arc length. arc length=25pi/3 centimeters, which is approximately 26.17993878 centimeters.
