My guess is that the Econotig might do your job. Not the best for very low current use, but a lot of performance for the money. In our part of the world, you should expect to pay about 5-600 for the welder, 850 or so for the complete package with either foot or hand control. weldersales
I know where you can get a used econotig with foot control,fingertip control,regulator with 2 flow meters,(not guages).Also has the stick holder that has never been used.If you are interested,e-mail me at tool_man67@hotmail.com and I will contact my brother.You can deal directly with him.
