new design welders
I have 4 welders, there is a big difference in what they will do.
The new inverters are a lot smaller and lighter. The old Lincoln ac tombstone buzz box does ok for farm machinery repair. It can be moved out to a power pole we have at a pump on the farm. I bought a used Lincoln Square wave Tig 255 , it is a big heavy machine, It will do tig and stick It has ac balance for tigging aluminum. My Lincoln sp200 Mig is also a big heavy machine, both need a forklift to move. I have an old Airco ac-dc hi freq I keep in the other shop. Not as good as the 255 but I can stick weld with Hi freq, easier welding rusty dirty farm machinery. I like the Duty cycle on the bigger welders, I can weld all day with one and not overheat it.
