Lincoln Weld-Pak 90i FC
#6 in 120 VFull review
A light, cheap flux core welder for occasional repairs around the house and farm. Buy the 90i MIG instead if you might want gas welding later.

Pros
- Holds 100 A for 60% of the time, long enough for full beads on sheet metal without stopping
- Auto-Set picks the settings from wire and thickness for quick, clean welds
- Detects a spool gun on its own for aluminum
- Runs full output on a 5,000 W generator
Cons
- Costs far more than most 120 V MIG welders
- Tops out at 3/16 in steel in one pass
- Three year warranty, shorter than Hobart’s five
