*Flux Cored welding is relatively inexpensive, pretty easy to learn, and pretty versatile. But it
has it's limits, so I recommend having a stick welder too.
* It's not a new process, being dated back to the 1920's.
* Instead of having the arc stabilizing flux on the outside as in stick rods, the flux is at the core.
At the local Weyerheauser Timber Company we would sometimes build car sills for railroad boxcars. Heck of a big job! We would use wire feed welders to do a lot of it. These units were basically 100% "duty cycle", meaning that we could run beads as long as we wanted without stopping for the machine to cool down.
For some of the flat type welding positions, we would also run "jet rod" (7024), which produces great beads and is very easy to knock off the slag.
I prefer flux cored welding over the use of MIG, using gases as the shielding method. A personal preference.
I recommend starting out at a bit higher Amp settings to help ensure that it's a bit easier to run, and to learn the eye-hand coordination.
Low end unit. Fewer
settings, lower Amps.
My unit. Good quality, more settings, higher Amps.
Higher end flux cored/gas welder, better for a business!
