Actually, duel welding would be a trade skill. You would need to learn it from a journeyman welder and buy a Lincoln Arcwelder to start out. Later you could attack members of your own faction (hence the duel nature of welding). This could be feasible if you connected your opponent to ground and then got close enough to generate an arc to him/her. Could be like the Gnomish deathray. Come to think of it, maybe it would be part of the engineering branch.
Unless of course he meant dual wielding. Funny how people who can't spell have trouble finding the right forum. I wonder if he is playing Star Wars Galaxies and stumbled into WOW forums instead?
