Anyone run cellulosic E6010 electrodes in TIG 210Ext?

Do you have to always keep tight arc or can you long arc on 210EXT? Like 1 or 2 inches of arc length? Sometimes I need to strike away from where I'm going to weld, then long arc over to start the bead..

I thought VRD was for safety reasons... turning it on/off affects the arc?

Thanks in advance.

Inverters have protection circuits that will shut off the arc if the voltage gets too high from too long an arc.

VRD is for safety, but I can see how it might make for a hard start depending on how fast it reacts.
