This welder will also weld all standard door frames to 14” wide and will weld hinges up to 18” in overall length when necessary. The standard weld control is designed to fire three transformers simultaneously for load balance and like the FRW1202A, it can be outfit with other name brand weld controls as well as being available in voltages from 208VAC through 600VAC for both AC and MFDC welding. This welder is interchangeable with the LORS brand Model 790.
