Review on SeeSii Upgraded Stick Welder 250Amp: Intelligent MMA Welding Machine with Digital Display, LCD and Hot Start Features - 110V Inverter, Electrode Holder, Work Clamp Included by Ricardo Fast

Revainrating 3 out of 5

Increase the amperage: Welding and soldering

I am new to welding and it has taken me a while to figure out the best way to use the Seesii welder. The welder itself is easy to use. There are negative and positive terminals that screw into the transformer, with a power switch on the back and a current regulator on the front. Clamp the negative jaw onto the workpiece and the positive jaw onto the end of the welding electrode. I used E6011 3/32" electrodes for mild steel and scrap metal. In terms of performance, it works, but it's not the easiest to use. The electrode is rated for 40-90 A DC/AC, so I set the scale to the first 70 A. The electrode stuck strongly and jerky welds formed when it wasn't sticking. The arc was difficult to adjust. I've increased to 90A with similar results wherever it stuck the electrode. Only when I increased it to 200A did it start to form puddles of melted water and it became easier to start the arc. There was still a bit of sticking, which decreased as we approached 250A, but this caused the electrode to melt more with molten metal spatter. So I don't think the current rating is too accurate, but I'm a beginner so maybe take that with a grain of salt. As always, surface preparation prior to welding is important to achieve the best results. I use an angle grinder to remove the surface oxidation. I've tried welding on both unprepared and prepared surfaces. The unprepared surface takes about 20 amps more to melt, has impurities and a slightly stronger melt, but is weldable. The construction is relatively solid, although it will take time to determine if there is any wear and tear. The electrode clamp is strong, but after only 10 tries up to 90A, the "copper" jaws seem to have worn down a bit around the edges. I'm not sure if they are all copper or just copper plated. The negative clamp isn't the best either. It's a "vampire" with two fangs on the sides of the jaws, so it touches the workpiece through 4 points that are in Harbor Freight (15 lbs). I'm not sure why there is such a huge weight difference between budget welders, but it raises some questions about the quality of their construction and performance. It is not that easy to use for a beginner. I've also seen cheaper ($76) Revain welders that seem to be more durable, but at the same time Revain welders' budgets vary. up to $200. It takes some practice and a significant amount of amps, but you can't get good welds in my opinion.

Pros
  • Hot arc start and welding power 20-250A
Cons
  • Some problems
