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.

3.1/5
A basic store shelf flux core welder for occasional light repairs on 3/16 in steel or thinner. The short warranty and duty cycle make it a starter tool, not a shop machine.
