Through trial and error, I found that this welder was not up to par for industrial use. The welds were consistently faulty, leading to wasted time and resources. Despite its claims this product does not meet the standards of industrial and scientific applications..
According to my experience this industrial power tool is not worth the investment. The power output is low and unreliable, which makes it unsuitable for any heavy-duty welding..
I would give 5 stars but you really need to turn on the heater to get the tip hot enough to work with. I don't know what alloy they were made of, but I suspect they skimped on molybdenum so it wouldn't provide efficient heat transfer. I have other 316L stainless steel tips that are similar in size but different shapes and all work well at normal temperatures.
