When shopping for welding soldering equipment, the first question is usually not amperage - it's how many processes you actually need. Both of these machines run gasless flux-core MIG, but they take different paths: one favors a lighter, simpler two-process setup, the other adds a third process and a higher amp rating. The 130Amp 2-in-1 Flux Core/Stick Welder is listed at $86.99, while the 145Amp 3-in-1 Flux Core MIG/Stick/Lift TIG Welder is listed at $68.00.
Quick verdict
Pick the 2-in-1 if you want a lighter gasless MIG/Stick machine with synergic MIG control. Pick the 3-in-1 if you want higher output and the ability to add another process later.
At a glance
| Model | Listed price | Price bar | Key difference |
|---|---|---|---|
| 130Amp 2-in-1 Flux Core/Stick Welder | USD 86.99 | 130Amp, 10.2 lbs | |
| 145Amp 3-in-1 Flux Core MIG/Stick/Lift TIG Welder | USD 68.00 | 145Amp, third process requires extra torch |
Where each machine makes sense
The 2-in-1 is the portability pick. It includes a MIG torch, electrode holder, and ground clamp, and its synergic MIG setting matches voltage and wire feed speed from the wire diameter you choose.
The 3-in-1 is the capacity and process pick. It delivers more amperage, can handle mild steel up to 2/5 inch thick, and adds Lift TIG as a third process - but only with an additional 10-25 Lift TIG torch. At 19.27 pounds, it is noticeably heavier than the other unit. In exchange, you get a bonus roll of welding wire and 20 welding rods.
Product notes
130Amp 2-in-1 Flux Core/Stick Welder
This unit is the lighter of the two at 10.2 pounds, with synergic MIG control built into the MIG mode. Pick a wire diameter and the machine matches welding voltage and wire feed speed; you can also switch to manual control for fine-tuning. The included components cover the essentials: MIG torch, electrode holder, and ground clamp. Its main limitation is output: it tops out at 130Amp, and you have two processes rather than a third Lift TIG option. For light DIY, garage, or farm repairs, this is the easier one to carry and set up.
145Amp 3-in-1 Flux Core MIG/Stick/Lift TIG Welder
This machine offers more amperage and another process, but the Lift TIG mode requires an additional 10-25 Lift TIG torch - so the 3-in-1 capability comes with an extra purchase. It is the heavier unit at 19.27 pounds, measuring 17.4 x 13.74 x 7.56 inches. What you gain is more output and the ability to weld mild steel up to 2/5 inch thick. The bundle includes a roll of welding wire and 20 welding rods. If your work calls for thicker mild steel and you want the option to try Lift TIG later, the lower listed price of this pair makes it the one to buy.
Final choice by use case
If you need a grab-and-go welder for light repairs, choose the 2-in-1 for its lighter carry. If you want the higher output and a potential extra process, choose the 3-in-1 - but plan on buying the separate torch to unlock that mode.
