  • Very good for the money
Review of the Simder 4050 MINI: This could be a great little welder or a bad welder, depending on your expectations. If you are looking for a Flux cored arc welding (FCAW) machine, then it will do well. If you need a MIG welder, look elsewhere, but don't expect to find a good one at this price level. This 4050 MINI can weld 1/8'' mild steel with E71TGS.030-Diameter wire and 120V and 3/16" with E71TGS .035 wire and 220V. An experienced welder, probably could weld 1/4" mild steel with E71T-11 035" (multiple pass welding). This welder can also be used for ARC welding, it has the same limitation as FCAW (only goes up to 140 Amp). Skill Level: Beginner Build quality: does not look cheap, one step above the ones selling at lower price (for example, the SSIMDER 140A MIG selling for 30% less the 4050 MINI) but not the same build quality as the step-up welders priced around 3 times higher. Ground Cable: low quality and short. Cables are expensive so OK for the price. I replaced the clamp for around $7 at my local tool store. I am not going to expend money on a grounding cable. I have a good quality jump cable (two 6-gauge cooper cables in parallel) that I am going to clamp to the short ground cable when I need to extend it. Welding gun: Comes with only one 8.mm tip installed (no spares or 0,9 mm tip included) The cable is a little short but longer that the grounding cable. Place it on a small welding cart or table and it should be fine. The gun comes with a MIG metallic nozzle. Replace it with a Gasless Flux Core Nozzle like the Vulcan that I got from my local tool store. I bought a kit from Amazon. It comes with a couple of threaded metallic gas diffusers and Gasless Flux Core Nozzles. Replace both parts. The gas diffuser that comes with the welder seems of better quality so I switched to the Vulcan slip-on nozzle. Power: you need a dedicated 120V 20 Amp circuit or better a 220V 20 Amp circuit. I also got a 25-foot 10 Gauge extension cord because I work outside. For most city dwellers, I don’t recommend doing this in your garage. User’s Manual: Poor. Not much info there. Settings chart: not available from manufacturer. Search for “HF Titanium Unlimited 200 settings chart”. Use the Flux Cored raw as a starting point. Divide de Wire Speed by 2 and use it to set the AMPS in your 4050 MINI. For example, for 1/8” steel the Wire Speed is 250. Set your welder to 120-125amps. Keep the Voltage at 0 adjustment value while you are learning basic welding. Warranty: One year. Unlike most other sellers, SSimder has a nice Web Site with a phone and email contact. I emailed them but did not get a reply. I doubt they are better in case a warranty claim is needed. Most machines failures occur at the beginning or the end of life. I tested the welder using 120 and 220V and up to 140 Amps 220V and 90F outside. It is still working. Hopefully it will be a reliable welder. PPE: Don’t imitate what so many youtubers do. Use the proper PPE for your eyes, head, hands, feet and body. Learning Welding principles: If you are a beginner I recommend Learn to Weld: Beginning MIG Welding and Metal Fabrication Basics Hardcover – Illustrated, October 10, 2014 by Stephen Christena (Author). About $15 from Amazon. It is a MIG book, but most of what he teaches applies to Flux Cored Welding. Get this welder or any other you like, at the same price level, all have the same limitations and similar capabilities. The 4050 MINI build quality seemed to me a little better than the lower priced welders. That’s why I bought it and decided to keep it. ... show more

  • It is pretty good
Style: SD4050Pro(2024)
I've been using it alot. I sometimes just go outside and practice on random metal it does well with anything I throw at it. Once you get over the fact of how much it is I think it will be great. The amount of features that come with it is great. I was always afraid of having to carry around multiple machines, but with this I only have to carry one! ... show more

  • Amazing beginner welder (read edit)
***The unit now pictured is not what was sent to me mid 2021*** - My unit had ONLY MIG and was blue in color also 160amp that was listed as 140amp. So This review may or may not be for the unit listed and is kind of a sketchy practice. I've been welding for 20+ years semi-professionally mostly exhaust and minor auto fabrication/bumpers etc. This thing is small and leight weight. Weld consistency is very predictable. The gauge may or may not be accurate as it states up to 165 amps and I feel like it hits pretty close ,but I've got no way to measure. Ordered what was supposed to be a mig 140 and received mig-160 as others have stated. It welds 1/4" steel fine. I wouldn't run long passes at max like that. I also have used it on a 20 amp breaker at 100 amp for long periods with no issues, cords didn't get warm welding 16 guage trailer fenders for several hours(3- 2lb spools). It welds better than my vulcan 140 I feel. -cons - short power cable and short ground cable. But the unit is light and cheap. ... show more

  • Inconsistent and unsatisfory MIG performance!
I purchased the Simder 140A SD 4050 Mini 3 in1 welder to have a MIG welder that was light and portable. The 90 amp Lincoln MIG welder I have works very well but is too heavy to be easily moved around. The Simder 4050 Mini stick welding function seemed to work very well. I did like the duel voltage input feature. The MIG function was inconsistent and erratic. Settings and adjustments were checked and rechecked without much improvement. The 4ft. Ground cable and 6 ft. Stick welding cable are too short to keep the welder safely out of the immediate work area. Poor quality ground clamp and stick electrode holder leave much to be desired. After all the time spent working with the Simder 4050 Mini I will say that it has potential, but I only give it 1 star and will return it. ... show more

  • "Cheap" meets good, but so for absolutely blows any harbor fright welder out of the water.
The only downside to this welder is the way you hook up gas is a little odd the hose just gets hose clamped, I've tried everything except stick and the plasma cutter and everything seems to work pretty dang good even on 120v so far doesn't get hot, no issues with any buttons. And actually like the way the display is set up just no real instructions. And a metal thickness to Amp diagram on the machine would be nice for us new guys. ... show more

  • Works but is very finicky, lied about amperage control
Style: SD4050Pro(2024)
I needed this for thin wall TIG welding. I wanted to use a foot pedal, it is only built for on/off pedals not amperage control ones. While I can still do the work required, it is not what I wanted. I would return it but it has been more than 30 days. THE FOOT PEDAL DOESN’T DO AMPERAGE CONTROL. It is only on and off. ... show more
