No Homework No Reason To Complain...
The issue with many, such as this fellow, is the simple fact they didn't take the time to do some homework & research.
Not all Chinese products are junk....although many are.
I own (3) Riland welders, a MIG250L 250A spoolgun unit that has run superbly for (3) years now(130+ 2lb rolls) without any issues.
My TIG unit is a Riland WSE200P 200A ACDC that I use for all the custom AL D/plate craft/auto accessories I make.
I have used it for 2 1/2yrs and has run 80+ lbs. of CS/AL/SS TIG rod flawlessly. My 3rd unit is a newly purchased Riland Cut60J 60A plasma cutter that got broke in cutting 1700ft. of 16ga shelving material & 750 pcs. of 1/4" stock.
I used (2) tips & the 2nd one is as new & still in use. I found this company to be one of the premier mfg. companies that does indeed put out a quality product for the fraction of cost of the big name brands.
I am a Miller man with (4) Miller units & use a Lincoln at work, so I know the ruggedness of these units.
The Rilands allowed me to expand my operation & provide a much better production ratio without the loss time to constantly change welding parameters/materials.
If you want a good product, simply do some homework & investigate company reputation, feedback, usage, & customer satisfaction with any product.
Another parameter I researched was the issues inherent with the combo, TIG/Plasma units that have a high failure rate because of component/design failures.
I found the individual TIG/MMA units & individual plasma units were much less susceptible to failures.
If you need both, then simply buy separate units.
now that is a good post.
