This is an excellent 200A multiprocess welding machine. Perfect size for making it portable. Welds everything I've put in front of it (1/2" SS Plate, so far). Doesn't struggle when trying to start cold. The Flux Core gun is one of the best I've ever seen. They certainly didn't go cheap on the quality. I would buy again and I'd definitely recommend this machine to family and friends!

For the money, you can't beat this little welder. It functions as it should and will serve anyone well for small jobs and lighter duty welding. Components are decent, the only thing I would like to see are better leads and connections. Upgrade the stinger and ground clamp and you'll be satisfied.

Waited a while to write this untilI really got some use out of welder. Bought it to use while my Hobart was being repaired, as it was taking a long time to source parts for repair. Mig on this machine is good,I have used much better, nèeds wire speed and heat adjustments, seperate. But heres where this little machine shines, I fabricated and made lift system and arms for my tractor, and welded up a new 8 x 16 foot trailer in 1 day using stick welder, burnt up almost 10 lbs of 7018 rods in 1 day. Did hit the overheat light a few times. I've done got my money back outof this machine. Just waiting to see how long it lasts.

The machine looks in excellent condition and welds with good power. The only thing I don't like is the cable connectors are too thin for a power of 200A. For the rest, everything is fine.

First one stopped feeding the wire after third use. I contacted Amazon and they were real quick to get another one out here to replace it. New one works OK so far with the stick haven’t used the wire yet. Hope it works as now it’s out of warranty. They only give you one month to find out so you need to try it out as soon as you get it.

Bought this for my husband for Christmas and he absolutely loves it! He said he can pretty much do anything he needs with it! Definitely good if you have to re-teach yourself if it's been awhile or for beginners!

コスパ最強で短時間溶接なら問題なく動作します。細かくスポット溶接の様にワイヤーを送ると本体ワイヤー入り口でたわんでワイヤーが折れてしまいますが、調整次第では解決するかもしれません。安いので、評価は満点です。

Just got it today no set up instructions I been wire welding since 1972 the cable on the front bottom left was my only issue. I did not know where it went so I went online to youtube it.After that I could get it welding. I just plug it in using the 115 volt standard house plug in. I was shocked at the first setting I blew thru 1//8'' metal so I put 2 haft inch dia. round bolts together and adjusted the setting lower made a perfect weld with the flux core wire. I cant even imagine what this machine will do plugged in to 230 volt !!! I just hope it holds up to future use. For the money you cant beat it. I'm going to buy another one and put it in storage.

i wrote a bad review at first talk to customer service with no avail. alot of peopel had problems with this thing.. i thought it was oiperator error so i didnt want to rush to get angry or return it i really needed a welder around ehre and this things was 200 bucks for a 4 in 1 welder.. so i bought it..i had problems woreking it at first becasue well.. operator error, so when welding in tig or mig settings you have to constantly hold the trigger as the wirse is feeding or it wont weld it will only spark..thats soemthing peopel had problems with so continuosly hold the trigger and itll weld.. as for the stick welding i havent tried it much yet but last time i did all it did was spark so as for the Mig and flux core settings i figured those out. i have done stick welding before but ill have to retry and paly aorund wiht the settings on it. it welds ok and has worked for a few projects so far...at 200 bucks it was a good buy but 400 idk ... the gun for stick welding also came broken and they said theyd sed me a new one but it never came..big surprise.

My welding machine arrived damaged, but it seems to be fully functional after I purchased a replacement stick holder. This is my very first time ever welding and I have had no formal training. The machine made it easy for me to make a first go at it. I did a practice run using the stick welding function as well as the mig function; all on just 110-120v 20amp outlet. The circuit breaker triggered only once, when I had the power setting on max at 200. Once I turned it down to 195 or less, I had no problem with the circuit breaker triggering off. I found the welder works well at 195 for stick, and 185 for flux/gasless mig.I purchased a box of 6013 and a box of 7018, but only tested with 6013 so far. The welding stick during my stick welding did get stuck a handful of times in the beginning, but it was easy to unstick just by moving the stick back and forth or side to side. I learned that the arc starts best when I slide the stick instead of tapping.The included roll of mig flux wire was nice, as I did not have to figure out what wire to purchase. I learned that I need to take off the mig cable to help thread the wire into the cable head, else it would get stuck and make a mess inside. I also learned that I need to take off the nozzle and manually work a piece of wire through the tip before using it else the wire would get stuck on it and the feeding mechanism inside the box would just bunch it up. Apparently, the included nozzles are not made to tolerance, but by pushing wire through it, it clears some copper at the tip that would otherwise cause the wire to not feed through.As stated, today was my very first time ever using a welding machine, and I think I did OK with the help of this easy to use machine. I did some research and bought nozzle gel as well as anti-spatter spray. I don't know how much it helps because I have nothing to compare against, but from what I understand, it makes the welding process a much better experience and I guess I have to agree because I did not have the problems of spatter clogging the nozzle nor spatter getting stuck on everything around me. The construction crew that built a stairwell for me left some waste pieces of structural steel, and I used four of those pieces for my first welding practice today. I managed to weld two pieces together using stick, then using mig. I felt the stick was much better for filling in the large gaps between the two pieces of metal that I was welding together. Once filled, moving the mig wire back and forth was great for creating a nice flow shaped weld, but by then, I learned I could slowly run stick weld to accomplish something similar. Eventually, I will try using the machine on a 220v circuit.All in all, this is a nice welding machine that is easy to use. Reliability and longevity is yet to be proven.
