I thought (based only on watching welders on youtube) that touching TIG
electrodes to the work was a real no-no?
You don't want to dip the electrode into the weld puddle, but that
different from striking the arc against the (solid) work before the
puddle has formed.
Does anyone really use the terms SMAW/GMAW/GTAW rather than
stick/MIG/TIG, or is that just an American thing, or a professional
welders thing?
Colleges seem quite keen on using the "proper" terms - to the point of
calling MIG, MAG in many cases (since most "MIG" gases have some active
(i.e. O2) gas content as well).
