    • Great little stick welder +/- with 7014 3/32 rod
Style: 110V
I am completely amazed at this little S7welder does very well+++++I have been welding since 1978 different projects from utility trailers to 1/16" flat plate and ALWAYS used the "OLD TRUSTED LINCOLN Red 220 A/C welder" AND always will (my Dad showed me how to weld back in 1971). So for the past 4yrs have been seeing advertisements all over the internet for these SMALL tiny welders, and always said ARE YOU SERIOUS????/ So was not sure how good they perform. And yes i have bought 4 DIFFERENT welders and they all seem to pretty well the S7 is the last welder/ It works very well and i could not resist the price i looked at it for 3weeks before i finally give in to it. I WILL NOT give up the original Red Lincoln 220 welder (old reliable) owned since 1978 ... show more

    • Easy to use, does a good job
Style: 110V
This welder performed great, I grew up on a farm and had some experience welding so I was not a true beginner, assembly was simple and the product performed as described, the only downfall was took a little time to dial in the right temps as the guides leave a little to be desired for details, it performs best with small diameter rods, for a hobby welder or people looking to add the ability to do some light welding this tool should do the job, I am unsure if it would hold up with daily use, but for myself who uses it maybe once every two or 3 months, it was a great value and worked well. ... show more

    • Stuck in a hard place
Style: 110V
I wanted to remove the head from the engine block of my2006 ScionXb. I tried to remove it using screw extractors but they didn't work. Bolt head extractors wouldn't work because they were to big to fit into the area where the striped head bolt was located. I knew I neede to tack weld a bolt onto a rounded out bolt head on an engine block in order to remove it, but my wire feed welder couldn't reach down in there, so I needed another option. I started seaching online for a stick welder because a welding stick could definitely reach the bolt. On the first page of search results I found this little stick welder for $69.00. I ordered it on a Friday and it was supposed to arrive on the next Monday. It actually was delivered before 10am on Sunday morning. I rounded out the bolt head some more so I could push another bolt in and weld it to the damaged one. It did exactly that with no problem. This welder is very small and lightweight so it can't be used to weld I beams on skyscrapers. But for tact welding and any other small projects that don't need continuous welding of beads, it is perfect. Crawing under a building with this unit would be much easier than trying to lug a millermatic 140 with you. I give this product 5 stars! ... show more

    • Easy to use for a first time welder.
Style: 110V
Took a few tries to get the setting right for the thin steel I was welding. But after that it worked very well. Compact design, I’ll keep this with my camping gear for repairs in the field on my mining gear.

This welder is VERY small, so I didn't expect it to be as impressive as it is. I ran through a little 3/32" 6011 at work just to fool around and see how it'll behave, no hesitation with the right amperage. 7018 in the same size was used to weld the hammer in my photos with this little guy. That's a 4lb head, schedule 40 steel, one pass after a tack weld. If you're a hobby welder, a mechanic looking for an easy little machine to use as needed but don't want to spend thousands, or even a farmer needing a small machine to do quick repairs anywhere, this guy is great. AND it's 110v, which allows you to work anywhere with a 110 outlet nearby. My only complaint is the welding leads are a little short. However you also get 2 extra connectors, so if you bought additional welding cable, and clamps, you can make longer ones. Thus this is a really small issue considering the price point. All told, no I didn't expect high dollar welder performance, or even harbor freight performance, but it beats those things with ease. Even for a novice it isn't hard to use. Absolutely worth the $70 or so. As I said, I'm considering getting another one later for work. Just to have it because what good mechanic doesn't have a welder in his shop? ... show more
