I do not have a torch as it costs too much to lease the bottles and refill the tanks so my Lincoln AC-225 becomes more of a tool for me than just a welder alone:
In lieu of a torch it is possible to crank the welder up and use 6011 rods to cut steel and to burn holes in steel. The Lincoln manual even shows a recommended sawing technique on how to do this. Some people claim soaking the 6011 rod in water helps when cutting although I have never soaked my rods when cutting or burning holes. Savey users can cut/burn holes such that almost zero grinding is required. Less savey users (like me) have to do a little grinding but it does work. I have an uncle that claims he can cut thinner sheet stock that requires no grinding(almost as good as plasma) by incorpoarting a straight edge and other techniques - I need to get him to teach me his tricks on this.
I also use my AC225 to heat metal with a Twin Carbon arc torch (NOT to be confused with carbon gouging or Arcair gouging which is totally different process). The Twin carbon arc torch will NOT cut metal but can be used to heat metal for bending/straightening, removing rusted nuts with or without flame, and to braze or silver solder. Savey user's can even improvise tig weld with one (I can NOT). My flames are more similar to oxy/acetylene with a rosebud tip, but I do not practice to attempt to make alternatively better flames either. Twin Carbon Arc can actually burn 1000 degrees hotter than oxy/acetylene's potential if desired. Buying electricity is still cheap comapered to buying gas for the infrequent user. FWIW Twin carbon arc is the one process where AC power actually works better than DC power. The two rods burn/consume evenly on AC power. DC power can be used too, but one rod will burn/consume twice as fast as the other one making it a little harder to maintain the ideal flame.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
