Suitable sharpening length depends on welding current which is used most often.

Low currents

Mean currents

High currents

Always make sharpening grinding lengthwise of electrode.

2.5.2.  A.C. welding

In A.C. welding the temperature of electrode tip rises a little more higher than melting point of 

tungsten and brings about formation of ball-shaped curved surface. On basis of tip formation 

and arc behaviour you can determine suitability of welding current for used electrode size and 

material.

Low welding current or big electrode size. Arc will be unsteady and is not directed 

on welding object.

Suitable current.

Too high current or too small electrode diameter.

You can speed up the tip formation by electrode change e.g. with following:

Adjust welding current a little higher than usually.

Burn arc to waste piece by keeping the torch in vertical position.

Arc is extinguished immediately after the electrode tip has become round.

Current is reduced to be suitable for work and welding is started.

You can grind the electrode partly at its tip at which the tip will be better ball-shaped and 

the arc more steady.
