I read the reviews listed with the welder and it seems most were happy with the machine. Several commented that it's barely hot enough to burn 1/8" rod, they had better success with 3/32". It should be ok for most sheet metal repairs and work ok for material up to maybe 1/4" but if you want to weld anything heavier it won't be very satisfactory. My experience has been hotter is better for good penetration and strong welds, especially on heavier metal.

The squeaky wheel may get the grease but it's usually the first to be replaced!
