I've had one for a number of year's, bought it back when they were still called a Dillon Torch. With the control you have concerning the heat range, you can weld light gauge mild steel, and chromolly with ease. With aluminum and stainless, the proceedure is much the same, but dose require the proper flux for each. The only thing that is an issue, is the fact that the gauges are not included. Low pressure gauges are what is needed, the ordinary oxy/ace gauges won't read low enough. (Two to four pound range) The low pressure ones are available, but are real pricey. I big difference I found was the pistol grip design, compared to a regular torch handle. Takes some getting used to, but is great in tighter spots since it's so short overall. I prefer it to the regular torch now.
