S7 Soldador MIG de 200 amperios, 110 V y 220 V 3 en 1 MIG & ARC & Lift TIG inversor gas/sin gas multiproceso de doble voltaje. máquina de soldadura

Works very well , compact and easy to use. It puts out enough to weld 1/4 inch steel no problem

Absolutely Love my welder. It's a Great Deal and best all around welder to learn on and beginner welders to get comfortable.Works excellent! Very happy with this welder for the price.

Thus far I'm shocked at what this lil guy can do on 220v.Only comes with a 1# spool of .030 flux core wire but boy howdy, almost no spatter and ran smooth. The dang argon/CO2 tank costs twice as much or more than the welder.Now that I've gotten a tank of 75/25 and solid wire I can say it's a darn good Mig welder as well.Only real down side is the wire speed dial doesn't have numbers but no big deal.

No inicia arco en modo flux, y no hay algún manual que enseña como usar la máquina, con electrodo revestido funciona bien pero con micróalambre no empieza a soldar.

Si cumple con las prestaciones que promete, es perfecto para el que va iniciando y si trabaja durante un buen tiempo, lo recomiendo ampliamente, hasta el día de hoy no he tenido ninguna falla, es de buena calidad.

Es una planta para soldar con excelente rendimiento, ideal para trabajos caseros, se la recomiendo mucho

Cumple con su objetivo, solo que la clavija trae un adaptador muy estorbos

El envío fue super rápido, lo recomiendo al 100%. La máquina está muy bonita, muy bien empacada y trae todo lo que promete, aún no la estreno pero espero que funcione bien y sea duradera.

Se recomienda al 100

Hasta el día de hoy me ha funcionado a la perfección

I'm a novice welder and bought this multipurpose unit to repair a couple of items for a friend who owns a golf driving range. I have done AC stick welding and some DC TIG (45 years ago) and can generally stick things together that won't come apart but the welds aren't very pretty...This unit arrived well-packaged and without damage. The unit auto-detects voltage, has good fit and finish, synergic operation, and is comfortably quiet with a five second or so cool down fan delay when the unit is powered off. It comes with an adequate stick stinger, an adequate ground clamp, an adequate MIG torch, a 2lb roll of 0.030 flux-cored wire, one 0.8/1.0 v-knurled flux core roller, three 0.8 contact tips, a spare gas shield, and a 2' long 220v to 110v adapter cable. It does not include a gas regulator, TIG torch or welding helmet.Wire, rollers, contact tips and gas shields are all of standard types and readily available for purchase at attractive prices. It should be noted that the knurled v-groove roller provided will accommodate 0.035 flux core on the 1.0 side of the roller.Cables appear to be of good quality and are about 6' long--on the short side (good for me, less bulk to stow), but long enough to do effective work adjacent to the machine which is lightweight and easily portable.Since I had to weld some thicker stock, I ran a dedicated 220v 50A drop to my preferred welding location and used that successfully. If I have a future requirement, I will put together a 220v 50A extension cord of adequate length. I haven't tried 110v operation yet.Harbor Freight has a low-end welding cart which easily accommodates this unit, its accessories, and a gas bottle should I venture into gas MIG or TIG welding in the future. It permits ready access to and stowage of the unit which is handy. I also bought their foldable welding table which permits better stability for the MIG torch when welding smaller items.Instructions for this welder were virtually non-existent. A quick internet search located instructions for a similar unit from another manufacturer that were well-written, intelligible, and effectively led me through the set-up process and considerations.As a novice welder, I'm not sure of what I don't know but was able to figure things out and make effective welds with a little experimentation. I practiced for an hour or two on some scrap of varying thicknesses I had laying around the garage to get a feel for wire speed and penetration, then had at it with the two repairs. With 220v service, I got good results using 0.035" flux cored MIG wire to overlay 3/16" plate onto 5/16" plate to repair a ball picker wheel mount. I then dialed things back to weld a probably 3/32" mounting bracket back on to a 3/32" mower deck without burn-through or other issue. The MIG torch is easier to use than my old HF AC stick welder as it enables me to get closer to and contact the work before I pull the trigger to strike an arc. Tack welding is easy even though this unit doesn't have a tack welding option.I can't comment on stick, TIG or gas MIG, but imagine similar good results.Overall, for a $150 unit, I'm delighted with my purchase!

I haven’t welding in 20 years and my last experience with mig welding was so so. This unit came well-packed and loading the .035 fluxcore wire was easy. After some practice welds I finished my main project without issue. Like others, the instruction manual is sirely lacking in useful content. Also, the lack of a “recommended settings” sticker for various wire types, metals and thicknesses makes fir a lot of wasted time and materials. Individual controls for voltage, wire feed speed and amperage along with either multiple displays or a single display which changed to display the control that was being adjusted (which would also lock the setting so it could not change when bumped) would be helpful. I don’t believe these changes would add significantly to the price but would make this 4 in 1 welder the best on the market…
