Great home welder considering low cost.

This is a very good mig/flux welder for the price. The synergistic setting which adjusts wire speed to amperage works well. No problem with wire feed. Negatives: cables are short and cheap. The build quality is unknow, but no problems so far. I purchased and recommend you buy the extended 4 yr warranty for peace of mind. It stick welds 6011 and 6013 ok, not so much 7014 and 7018. Forget stick welding 6010. I did a little Tig welding, seemed OK. Reviewers report that it's falls well short of 200 amps (more like 160 max) amperage with 220v. I own quite a few Mig welders (Tweco 210, Hobart 190, Miller 215). At a mere $99, this welder holds its own for doing household repairs. You can't beat the price. The mig gun cable, stinger and ground leads are short. I replaced the ground and stick stinger cables. The short mig gun cable (5 Ft) works for me but could be a deal breaker depending on the reach you need for the work you do. Reviewers found it's maximum output is about 160 amps on 220v. Plenty of power for work I do. So far so good.

Nice MIG welder for half the price!

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!

Equipo muy complicado físicamente exclusivamente producto...

Ya abrí el paquete pero aún no la uso, pero físicamente se ve impecable cumple con todo lo que indica físicamente 110-220V. Pistola MIG y sus accesorios con el rollo de alambre y todo. Muy bien elaborado y se ve de excelente calidad.

Handy little welder.

Great little project welder! Seems to be pretty good quality for the cost. Haven’t had the chance to check the heat level on the 220 side but the 110 maxed out does good enough for my needs. Excited to use and learn more about welding!

It's a Secret

Machine comes with no Product part list. Instruction manual is less than useless. Download the product PDF and prepare yourself for a laugh. Follow pdf instructions for wore insulation and LAUG harder.Didn't expect the manual or pdf to teach me too weld but it would be nice to know a parts list, so I know if I received everything, the possibly JUST THE BASIC MCHUNE SETUP.It's quite possible that a users manual and parts list was left out of mine but I doubt it.Tried YouTube S7 200A welder for information. NONE.Not saying it's a bad product but as of now it makes a Great Paper Weight.Oh might I add The paper the call a Manual, English translated from Chinese. Makes no sense if it's you're first time purchasing a Chinese product and reading what they call Instructions.Shirt Note.I'm 70 plus years old and have been in the Trades for 52 years pride myself in being able too read and follow direction and consider myself fairly knowledgeable in all building trades. So in closing if you're just a homeowner with little or no knowledge of mechanical things STAY AWAY.MR. B

S7 la bella y la bestia fusionadas 👌🏼

10 estrellas para el producto. Hombre descubrir soldadora regia, hombre ser feliz. No miento, quiero comprarme otra soldadora de las mismas solo para tenerla de reserva y otra que es para soldadura MMA de 250 amperios de la misma marca S7. Señores si quieren tener una buena soldadora no lo duden, cómprenla. Acá en Colombia varios amigos la vieron, la probaron y quedaron fascinados por el diseño, el precio y su excelente funcionamiento y ya empezaron a pedirla. En Fluxcore trabaja con alambre de 0.8 y 1.0 y en MIG con gas trabaja con alambre de 0.8. Trabaja con voltaje 110 o 220 y el cambio lo hace automáticamente. De verdad es una máquinota muy bien hecha y muy resistente, el color es agradable y la pistola es bastante robusta. Tip para el uso del Flux core. Usen Vaselina pura en la punta de la pistola para que no se les bloqueé la salida del alambre por las chispas al soldar, la veselina pura funciona de maravilla. ¡¡¡Gracias al vendedor y gracias a Amazon por el envío a Colombia!!! ¡Los felicito por tan buena logística! 🌟🌟🌟🌟🌟🌟
