Choosing a 110V MIG welder usually comes down to how many welding processes you need and how much kit you want for the price. Four flux-core MIG machines are compared here, with listed prices from $50.99 to $99.99 and process options ranging from a 2-in-1 MIG/Stick unit to 3-in-1 MIG/Lift TIG/Stick models. If you're adding to your welding soldering equipment setup, this guide shows where the practical differences actually sit.
Quick take
- The 2-in-1 MIG/Stick model is the simplest setup and the one with the most modest process list.
- The three 3-in-1 models add Lift TIG, which the 2-in-1 does not offer.
- The two 145A machines sit near the same price point but differ in weight and the TIG torch situation.
- The highest listed price belongs to the model that comes as a ready-to-weld kit with a welding helmet.

Product notes
MIG Welder 140Amp, Flux Core MIG Welder/Stick 2 in 1 Welding Machine, Welder Mac
This machine keeps the process list simple: flux-core/gasless MIG or Stick, with up to 140A output. The synergic control automatically optimizes welding parameters when you set the wire diameter, which helps a new MIG user get started. The listed components include the MIG welder, a 2 lb spool of .030" flux-core wire, and a 10 ft 300A earth clamp. If you only need MIG and Stick, this unit covers those jobs without adding Lift TIG complexity. The limitation is equally direct: there is no Lift TIG mode, so anyone planning to weld with TIG would need one of the other machines here.
140A MIG Welder, 3 in 1 Flux Core, MIG/LIFT Tig/Stick Welding Machine 110V Porta
This model pushes the feature set further: flux-core MIG, Lift TIG, and Stick are all available, and the package is a ready-to-weld kit that includes a welding helmet. The LED digital screen displays voltage, current, and other parameters, which is useful for dialing in settings. The synergic control matches wire feed speed to wire diameter, and the included bundle lists the 140Pro MIG welder, MIG torch, electrode holder, and ground clamp. The trade-off is that it carries the highest listed price on this page. If a complete kit, helmet included, matters more than the cost gap to the 145A models, this is the one to weigh.
haxiaoer MIG Welder 145A 110V, 3 In 1 Flux Core/Lift TIG/Stick Welding Machine
The haxiaoer 145A brings three processes to a 110V platform: gasless flux-core MIG, Lift TIG, and Stick. The control system adjusts settings when you change wire thickness or amperage, making it a candidate for someone who wants automatic adjustment. It lists a digital display and semi-automatic feed, with an 11-pound weight that suggests a portable shop unit. The catch is the Lift TIG mode: an extra torch is required, so the package as listed won't cover every process on its own. If you already have a TIG torch or plan to add one, this 145A machine is a balanced middle option.
145A MIG Welder, 3 in 1 Flux Core/Lift Tig/Stick Welding Machine 110V IGBT Inver
This 145A IGBT machine is the lightest of the four at 7.48 pounds, and it still offers flux-core MIG, Stick, and Lift TIG. The smart synergic control auto-adjusts voltage and wire speed based on wire diameter or amperage, and the LED display shows real-time amperage and wire diameter. The listed output range is 30-145A, with carbon and stainless steel in the 1-5mm range. The main limitation is stated plainly: the TIG torch is not included and must be purchased separately. For a compact 110V welder that you might carry around for repair jobs, this one stands out because of its low weight and the fact that the TIG torch is the missing piece.
Final recommendation by use case
For a straightforward MIG/Stick machine with the least complicated process set, the 140Amp 2-in-1 MIG Welder is the practical pick. If a ready-to-run kit with a welding helmet and a third Lift TIG process sounds more useful, the 140A 3-in-1 welder is the well-equipped option. If you want a 145A multi-process unit and don't mind supplying a TIG torch, both the haxiaoer 145A and the compact 145A IGBT model give you that capability in different physical packages. The haxiaoer is the larger 11-pound unit with a semi-automatic feed; the IGBT model is the lighter 7.48-pound option. Choose by whether portability or a more familiar control setup matters more to you.
