More than one welder is the norm for me. I have found out that there is no do everything welder. I have 4 welders (5 if you count the O/A torch set), a Lincoln Tombstone AC, a generator DC welder combo for using where there is no commercial power, a HF wire feed for light quick work and a Hobart 187 handler MIG that I use the most. They each have their place in my shop.
