no, this isnt martha stewart. i thought since i have not seen anything posted about this ,lets throw some ideas out there to help out when in a pinch. a few examples that come to mind ; a grinder can run off welding leads,if a cord isnt handy.used to carry a female end of a power cord about a foot long with two wires sticking out to ground to and clamp the rod holder on for power when working up in pipe racks.now i only used this when power through the cord gets lost or someone walks by and unplugs it to plug theirs in.and when your 50 foot up in a rack it can be a pain to keep climbing down to check on it.need at least 100 amps for a grinder to be effective.
althought there has been many threads on sharpining tungsten,another way which has not been mentioned is using a torch.by holding the tungsten and spinning it by your fingers or drill,while the torch is in the cutting mode will work much like sharpening on a grinder .now i know its impractical ,but it is possible and can make a very sharp point.
getting porosity in a weld is never a good thing,getting it in a weld that is to be checked by x-ray or u t is a repair and a strike.there are times when an end grinder or side grinder wont fit to grind it out.you can tig over it with stainless to suck it out, done this many times,and yes i know this isnt procedure.
one more for the road,a tig torch makes a great temporary electrode holder ,the collet size dictates the size of rod to hold.prett self explanatory.
soooo,lets hear some others out there.
