Hi Again. I'm doing a review of the S7-250 DC Arc Welder I purchased second hand but it was never used, well according to the hours shown on the machine. I wanted to know how good this little tiny 8lb welding machine can actually run on 3/32 and 1/8 rods. So I burn a few to find out.
I used this little inverter welding machine to run a series of videos I have been interested in for rejuvenating 12 volt vehicle batteries. If you would like to watch them then give it a watch. just click on my channel and run through the videos. It is a good watch and shows from start to finish how I ran my set up.
Thanks for the review, this machine seems to work well for you 👍 what did you set the arc force to?
I set it to the max. Deeper penetration
Hey so I got the exact same one, using it off my dryer outlet and a breaker box thing. But it will not stay on once I cast my arc. Tried changing my grounds changing amperage and I couldn’t get anuthing to work. Any suggestions?
Are you using the 120 volt outlet. The small prong or the larger adapter one for 220 volts. I only use the large adapter plug in as the little 120 volt one doesn't have enough juice to keep a strong arc in my opinion. If you use 3/32nds it may hold the arc but definitely won't work for 1/8" or larger rods.
@@brassskills6084 I feel i may have gotten a faulty welder as my friend uses the same setup no issues
@@vincentbarnes111 yeah. Should return it if you can and see if they'll give you another one
@@brassskills6084 thanks man! Giving you a subscribe
Absolutely useless. Machine has many parameters, and you didn't discuss any but one!
What parameters did you want to know? It can weld 3/32, 1/8, e6010. 7018, 6013. The basics. It's able to do a complete 14" electrode. It's a little welding machine. It's worth the money! It was $70 at a pawn shop. It's $110 right now on Amazon.ca. weld one full rod. Let machine cool a couple minutes. Weld again. It's not rocket science!
I want see the welder machine bro
It's an s7 arc welding machine. Costs $110 on canadian amazon.ca. you can switch the stinger and ground for electrode positive or negative. Good little machine for hobby work.
Thanks bossman I need one
For the small works 👍
I got the Yellow version of this little hotbox!!! Haven't tried it out yet but on immediate unpacking, I tried flexing/squeezing the electrode clamp, the clamp broke out of the handle housing it. Upon inspection of the broken mount point, I recognized the handle material was made from high temperature glass impregnated plastic...the same type of plastic used for housings of copy machine fusers (heat bonds toner to paper). Anyway, this plastic is not resilient to high impact or flex stress...breaks quite easily. While replacing electrode holder with a Harbor Freight one, I discovered what I believe the lead wires to be CCAW--Copper Coated Aluminum Wire, which in my opinion is quite the no-no for current heavy devices...should be pure copper!!! Thanks for the Video!!!😁👍🏻
How much did you purchase your machine for. And dam....the clamp broke 💔 lol that's brutal. I tend to just take it easy on any equipment I purchase. This one I found so cheap so I just ran with it. What do you expect for $60. I wasn't expecting much but I was pretty darn surprised at what this little machine did for me. I wasn't expecting much but it sure gave me a hell of a lot more the nothing lol. I read reviews on these things. Like them not working after first arc strike and what not, but in my case it hasn't done that to me. Luckily "cross my finger and knock on wood"
Hi, how do you connect your S7 to 100 or 220? Also where do you connect positive - to work piece or holder? Instructions show positive connected to holder, but it looks like you connect positive to work piece, is there any reason for that? Thanks.
Hey man. Yeah I use 220 volt. Should have an adapter that came with the little unit. You should be able to weld either DC + polarity (reverse polarity) or DC - polarity (straight polarity). It all really depends on what type of welding electrode you are using. Each electrode has different manufactured recommendations that you want to follow. DC+ is what I prefer when using E6010 and it gives deeper penetration on thicker metal. Let me know how it goes. Or if you need any pointers. Make sure to put your arc force up to max and the hot start on. Will make for less sticking and easier arc striking
Hey yeah. Now I remember why it looked funny. I was recording myself so it showed mirrored. I am right handed but when I recorded this way it showed me welding as a left hander lol. So positive for the electrode and negative for the ground. But everything can be welded with different polarities, just gives you different results.
Does it weld stick alumineum?
It should. Haven't tried it though. But welding stick aluminum won't look nice. Just for minor fixes. Good question though
