Weld finishing:

Arc welders use electric current generated by a transformer or a generator to produce a uniform, clean welds that almost never require finishing. This is not the case with gas welding. Gas welding operates using the heat generated by the ignition of a gas mixture (oxygen and acetylene) to melt the welding material or to simply fuse two parts together. This process often results in a bad surface finish. Gas welding can require additional work involving hours of grinding and polishing the welds.
