Here are my thoughts... I don't claim to be an expert, but was in your shoes a few years ago. I took a class to learn how to weld and borrowed a buddies welder until I could afford my own. I have been welding now, at least once a month, for several years. I am by no means a great (or even good) welder!
I agree with some of the advice that has been given... others (like buying a cheap welder) not so much.
If you buy a cheap welder, especially as a beginner, it can be difficult to know why welds are or aren't turning out good. Is it because the machine sucks? Is it because the cheap ass harbor freight wire that came with the machine sucks? Is it because my skills suck? Is it because the machine setting are wrong?
There are lots of variables in welding and welding is hard enough without wondering if a cheap machine is to blame for poor welds. If you buy a quality machine, and at least one size larger than you think you need - you eliminate MANY potential headaches and can focus on improving your skills. And you will wind up with a welder that should last a lifetime.
I think you should learn the basics before you strike an arc - maybe you already have; I don't know. I think GMAW/FCAW welding can give folks an undue sense of success since making a good looking weld doesn't take that long. Keep in mind that there is much more to welding than a good looking bead... and this is why reading and/or taking a welding class is invaluable.
I think you will get advice from three types of people on this...
- Some bought the cheapest thing that will get the job done. There is nothing wrong with this, just some drawbacks as mentioned above. I am not going to sit here and tell somebody that they wasted there money on a HF welder... Many people have had good luck with this approach. Who am I to tell them otherwise... Hell, i picked up the $150 HF band saw. Its a piece of crap in terms of quality and usability, but works great when its running good.
- Some will buy the absolute best (within reason). More power to them, at least they know they are getting quality. Only problem here is that most of us can't afford this. I think this is the type of mentality you find on Pirate quite a bit - "if you dont have the best then dont bother". I also think this is part of the "Keeping up with the Joneses" thinking. For many of us, a Miller 210 would be nice, but just not necessary.
- I fall in the middle... Give me the best bang for my buck. This usually means I spend a little more than I originally wanted, and get a real good quality product that may be a little undervalued (or deeply discounted). I did a bunch of research before I bough my welder and I found that the Hobart 180 and 210 are REALLY good machines for the money. Are they the best? Certainly not, but its a quality machine and I fully expect my welder to last for many, many years. I went with the 210 and couldn't be happier. Made in the USA, many parts are interchangeable with Miller machines, etc
The point of my ramblings? This questions comes up all the time... and If you can figure out what kind of person you are and what you want to do with your welder, you will get much better advise on a welder that will suit your needs.
