Very pleased.
The machine seems well built with sturdy hinges and handle. The shell of it is solid without a "tinny" feel to it. I have been mig welding 3/8 steel. Works great. The plasma cutter worked good on 1/2" steel and was very clean cutting on anything under 1/2 inch. This combo machine had the highest duty cycle in this price range. I have it at maximum settings on a 30 amp 220v breaker and it hasn't tripped it. So far I am very impressed. It's very impressive the capabilities of what this can do for this price. Now hopefully it lasts a long time.

Great little machine.
I've used this welder a few times. Have used the plasma cutter, the MIG welder and the stick welder. So far. This thing works awesome with no issues. Very pleased with its performance and its duty cycle.

Powerful at a weak price
At its price point, this is one of the most impressive machines I have used to this day. Iโve been welding for close to 20 years now and this thing lays down when you want it to. I run it as a piggy back machine off of my older miller trailblazer (generator 220v power) and Iโve put about 100 pounds of wire through it so far 10 10# spools in a few weeks time only had it over heat 1 time because it was sitting next to the trailblazer which was throwing off substantial heat. Iโve now relocated and havenโt had that problem since. I ran it nearly maxed out welding 1/2 plate steel to 1/4 plate steel for about 4 hours straight with no issues and excellent penetration. If you are having problems with this machine itโs more than likely user error or wrong settings, do yourself a favor and do some research on proper settings and technique. The plasma cutter on it performs well with light duty cuts but will struggle cutting heavier plates for a long distance. It will cut through 1/4 plate like butter but anything thicker requires a little more attention. The only real flaw I can find with this machine is it is not capable of AC current (tig aluminum) other than that it exceeds performance expectations for anyone looking for a home or garage welder. I use this thing to make money and itโs paid for itself 13 times already in just a few weeks. At that rate Iโll buy one once a month if I have to.

All in one welder
Love this welder! Would be great if you could buy as a complete bundle with welder,spool gun, and gas regulator in one package.

Gentle
I blew my life savings on this hunk of plastic. 110 stick was hard to arc at first then nearly impossible however Iโm sure much easier with 220. MiG gun was fine. Easily to operate and figure out without reading instructions. Be careful with gas I blew the internal gas line with only 60 psi of argon. I had to fix it myself since the warranty changed from 90 to 30 days after purchase. I do like consistency. If treated like porcelain figurine it may last a year id love to wrong though. Good luck

Sunstac , great all in one machine so far....
I really like this all in one machine, it does a remarkable job for the price , it had a few items that was missing but the seller took care of the problem, I also ordered the yeswelder. 030 and .035 flux core wire it did such a good job I have ordered a total of 9 rolls of both sizes of wire , I would recommend this all in one machine for anyone that needs to work on equipment or vehicles or anything made of metal, everyone have a great day, and a big thanks to the company for their great products.

Junk
VeasaaaI bought this welder recently , it was missing a couple of air line / regulator fittings, and tubing, for the plasma cutting feature a flippin nightmare to resolve. Very long story short- I now the have the stuff,and installed same. For some weird reason, I like this little toy. looks like I am ready to connect, or separate some metal . I will update this post as soon as I have a chance to actually use it. 5/5/25. Tried welder today. At any wire speed, or heat, the wire quits feeding thru the liner/gun as soon as arc is struc, Changed feed roller, adjusted roller tension, ect. Sending this crap back.

Input Current Ratings, they differ for each feature and input voltage
Though I have yet to weld or cut anything, I wanted to share the electrical ratings given in the manual to help potential buyers make a more informed decision about current draw and what size circuit breaker might be needed for each feature of this machine. For the record, I plan to do nearly everything on 220 volts AC, but at the moment, I only have a 30 amp 220 circuit and a 30 foot 40 amp RV extension cord and all of my cutting and welding will be done outdoors. Also, I will only be using the Plasma, MIG, Flux and Stick welding features (yes I know about shielding gas in windy environments, I'll try to make accomodations when possible). Also, understanding how much functionality is packed into such a cheap machine, I will be very cautious and try not to overdrive it in hopes of making it last for as long as possible all while using it semi frequently all year in every weather condition from hot/humid, warm/rainy (under a canopy) to frozen/snowy all outdoors as I have no garage/shop (yet), but always have need to fabricate and construct or repair heavy equipment for other local small contractors in asphalt paving. If something goes ZAP and it is larger than an integrated circuit, I am competent to repair it myself. All of the above being said, I preemptively gave this unit 5 stars as it's everything a steel welder could hope for in one cheap lightweight box, and it's way more visually pleasing than my baby blue Yeswelder TIG205-DS. Should my expectations be sorely mistaken, I will edit my review appropriately.
