OP, I think we really need some more context here. What type of welding are you looking to do? And how often do you plan to do it?
As stated (repeatedly) anything Lincoln or Miller will be great. A lot of other good brands also, but I’m unfamiliar with those. I run RED myself.
But, when you say “welding equipment” rather than “welding machine” I assume you are talking about PPE (jackets, sleeves, gloves, helmet), electrodes, torches, clamps, hand tools, etc. I’m not loyal to any one brand for most of these items, but when it comes to electrodes I stick pretty tightly to Lincoln. I’m also partial to Tillman gloves, but not so much that I don’t try on other brands when I see them. I’ve got several different hoods of varying brands, and I don’t think I could confidently choose a favorite. Different types of work call for different types of equipment.
