I will not give a complete review until issue is resolved. I sent a email to Tech Support waiting answer. Issue is plasma cutter comes on initially, will not reignite for second cut. All connections are tight and metal is new and clean.Air is ample and only air comes out with no spark. Not sure, but power light stays on even when unit is in off position. Review is for plasma only. welder is good so far. Alot of plastic in construction of both units which reduces cost but makes for lesser quality than metal housings and connections.Get this resolved and I will give a much higher review.
