GWEIKE M800
#7 in Up to 1,500 WFull review
For a small shop that wants air cooling and a two year warranty at a fair price. It is heavy, so plan on keeping it on a cart.

Herolaser T700 Air-Cooled
#12 in Up to 1,500 WFull review
For a hobbyist with no 240 V outlet who welds thin sheet. It is the lightest full-function welder here, but the missing warranty is a real risk at this price.
