What happens to the weld as the electrode extension is lengthened?

To determine

The effect of length extension of electrode on the weld.


As the welding is done on Constant potential (CP) power supplies the welding current changes as the length of wire changes. The slightest change in the electrode extension can affect the weld. As the extension or reduction of electrode can increase or decrease the resistance of wire respectively.

As wire extension increases the increased electric current heats up the wire and creates a heat buildup zone at the tip of electrode. In CP supply the voltage remains constant thus; the amperage changes as wire shorten or extend from the contact tube...
