3. ENERGY CONSUMPTION.
Shop welding operations are almost always electrically powered. Field operations may be electrically
powered or powered by generators. Some field welding equipment is directly engine driven. Power
requirements depend more upon electrode diameter than welding process. SMAW, FCAW and GMAW
welding equipment draws essentially the same current ranges, and SAW, ESW and EGW draws more
current to provide the higher deposition rates achievable and desired. The total power consumption
difference between processes for a given joint configuration is negligible. To save energy, the minimum
weld size and minimum groove cross-sectional area adequate to carry the load should be specified.
