The spec that splits these five machines is the current range, not the brand name. Amp output decides what you can weld and how thick the metal can be, and the Lotos portable welder listings here run from 20-120A all the way to 20-200A. Buyers tend to over-weight weight and size, but the amp ceiling is what actually stops a job halfway. The Lotos TIG200ACDC leads on the spec that matters most for metal variety, since it’s the only one here with AC output for aluminum.
Head to Head on What Matters
Current Output and Metal Thickness
The Lotos 200A Stick Welder states an adjustable 20-200A range and says it welds metal from 0.06 to 0.2 inch thick. The Lotos TIG200ACDC lists 10-200A in AC/DC TIG and 15-200A in DC stick. The Lotos Handheld ARC Welder steps down to 20-120A, and the Lotos 135A MIG Welder tops out at 135A for mild steel up to 3/32 inch (2.5mm). The Lotos LTP5505D Plasma Cutter works in a different unit entirely, a 55A cutting arc with a 5/8 inch (16mm) clean cut capacity, so it doesn’t compare on welding amps at all.
What Comes in the Box
The Lotos 200A Stick Welder includes 20 welding rods, 2 chip hammers, and a pair of welding gloves. The Lotos TIG200ACDC package lists a TIG torch, MMA/stick clamp, foot pedal, argon regulator, a 220V/110V converter pigtail, ground clamp, and a consumable set.
Input Power and Where You Can Use It
The Lotos LTP5505D Plasma Cutter and the Lotos TIG200ACDC both state dual-voltage input, switching between 110/120V and 220/240V automatically. The Lotos 200A Stick Welder, the Lotos Handheld ARC Welder, and the Lotos 135A MIG Welder are all listed at 110V only.
What the Numbers Mean for You
A 200A ceiling versus a 120A ceiling isn’t a small gap in daily use. Weight matters less than it sounds: 3.3 lbs and 3.7 lbs disappear into a backpack, while 11.4 lbs is a two-hand carry. Bigger numbers stop helping once your metal is thinner than the machine’s stated range — extra amps you never dial in are just unused headroom.
1. 200Amp 20PCS Rods Stick Welder
Best for: Home repairs, DIY, and thick metal on a household outlet
This one wins on raw welding range. The 3.7 lb body and 7.8 x 3.9 x 5.3 inch size mean it goes in a backpack or toolbox. The listing names E6013, E6011, E6010, E7018, and E308 rods, and notes that stainless needs E308L-16 rods only.
Pros
- Adjustable 20-200A with a stated 0.06-0.2 inch thickness range
- 3.7 lbs, sized to fit a backpack or toolbox
- Includes 20 welding rods, 2 chip hammers, and welding gloves
- Hot start, anti-stick, and arc force functions, plus over-voltage, over-current, over-heating, and overload protection
Cons
- Listed at 110V input
- Stainless steel limited to E308L-16 rods per the listing
2. Lotos Handheld ARC Welder
Best for: One-handed touch-up work and small repair jobs
The handheld shape is the whole point here. Its compact, lightweight build is made for one-handed operation, which suits quick repairs where clamping a machine down and running a lead is more setup than the job deserves. The 20-120A output runs through a 5-speed knob, and the listing names carbon steel and iron as the materials, so it’s aimed at light work rather than structural plate. Hot start arc ignition and a stated 360° cooling design with overheat protection round out the daily-use side. It’s not the pick for anyone welding thick material, since 120A is the stated ceiling and the rod support is listed at 3/32 inch (2.5mm). If your projects are fences, brackets, and auto body patches, the smaller package is the reason to choose it.
Pros
- Light enough to hold in one hand for quick touch-up work
- 20-120A output with a 5-speed current knob
- Hot start arc ignition and reduced spatter per the listing
- Internal 360° cooling with built-in overheat protection
Cons
- Listed at 110V input
- Rod support listed at 3/32 inch (2.5mm)
3. Lotos 135A MIG Welder
Best for: Beginners who want wire feed and three processes in one
This is the most versatile machine in the set, and the listing backs it up with three processes: gasless flux core MIG, stick, and lift TIG, with a separate lift TIG torch required for the third. The trade-off is weight and reach: at 11.4 lbs it’s the heaviest welder in this listing, and 135A covers mild steel up to 3/32 inch (2.5mm).
Pros
- Three processes: gasless flux core MIG, stick, and lift TIG
- Synergic control matches voltage to wire feed speed automatically
- Includes E71T-GS.030 and.035 flux core wires
- Oversized LED display with real-time current readout
Cons
- Lift TIG requires an extra torch, sold separately
- 11.4 lbs
- 135A output, stated for mild steel up to 3/32 inch
4. LTP5505D 55A Pilot Arc Plasma Cutter with Rust Removal Mode
Best for: Cutting and rust removal, not welding
This is the odd one in the group, and that’s the honest way to read it. It cuts rather than welds, with a 55A arc and a stated 5/8 inch (16mm) clean cut on stainless, alloy steel, mild carbon steel, copper, and aluminum. The continuous non-touch pilot arc fires without touching the workpiece, which is what lets it track across painted, coated, and expanded metal without stalling. Dual-voltage input switches between 120V and 240V automatically, and a front-mounted air regulator lets you adjust pressure at the bench. This isn’t the pick for someone who needs to join two pieces of metal — for that you want one of the welders above. For cutting plate to size before you weld it, it does a job none of the others do.
Pros
- 55A cutting arc with a stated 5/8 inch (16mm) clean cut
- Continuous non-touch pilot arc for coated and rough metal
- Rust removal mode for oxidized surfaces
- Automatic dual-voltage 110V/220V input with front-mounted air regulator
Cons
- Cuts metal; it doesn’t weld
5. TIG200ACDC 200A AC/DC Aluminum Tig Welder with DC Stick/Arc Welder
Best for: Aluminum TIG and the widest metal range
This is the most capable machine here on material variety. The 200A AC square-wave output is what makes aluminum welding possible, and the foot pedal gives you heat control through the weld rather than just at the start. The trade-off is that TIG needs argon gas and a foot pedal you operate with one foot while both hands work the torch, so it asks more of a beginner than the stick machines do.
Pros
- 200A AC/DC TIG output for aluminum, stainless, and steel
- DC stick at 15-200A with adjustable hot striking arc current
- Dual voltage 110/120V and 220/240V input
- Includes foot pedal, argon regulator, TIG torch, and consumable set
- Stated money-back guarantee, replacement, and limited warranty
Cons
- TIG welding requires argon gas, supplied separately
- Foot pedal control adds a step for a first-time welder
Also Worth Considering
The Stick Welder runs 200A in ARC or lift TIG and takes both 110V and 220V, which suits a shop with either outlet. The Mini Welding Machine is a 250A MMA unit with hot start, arc force, and anti-stick, and it ships with 20 welding rods. All three are stick-first machines, so read the rod list before you commit.
Frequently Asked Questions
Is a higher amp rating always better?
No. Higher amps let you weld thicker metal, but the machine’s stated thickness range is the real limit. A 120A unit covers thin sheet fine. Extra headroom only helps if your projects actually need it.
What does it mean if a spec isn’t listed?
It means the seller didn’t state it, not that the machine lacks it. Treat unlisted specs as unknown and judge on what the listing does print — output range, included accessories, and stated warranty.
How do I compare two machines with different units?
Convert first. One listing may use inches and another millimeters for the same thickness, so match the units before you compare. If only one listing states a figure, the other is unknown, not worse.
Does portability mean lower power?
Not automatically. The 3.7 lb Lotos 200A Stick Welder states the same 200A ceiling as the far heavier TIG200ACDC. Weight and output are separate specs, so check both rather than assuming one follows the other.
Closing
The Lotos TIG200ACDC wins on the axis that matters most — metal variety, with AC for aluminum and the fullest package. If you’re not sure which axis you care about, the Lotos 200A Stick Welder is the safer choice: wide current range, light body, rods included. Check the current specs and package details on Amazon.
