Overview
Performance
The PUWU CT-418PRO is designed for versatility and consistent performance across multiple welding and cutting modes. When powered through 220V, the MIG output peaks at 200A, making it ideal for medium-thickness steel, stainless, and aluminum applications. On 110V, it still delivers a strong 130A, sufficient for home and light workshop use.
The arc stability is surprisingly good for its price range — especially in Stick and TIG modes. The machine handles cellulose electrodes like 6011 without spatter or arc wander, which many low-cost inverters struggle with.
On the plasma cutting side, the PT31 torch performs efficiently with clean cuts on mild steel up to about 3/8″ (9.5 mm), depending on air pressure and quality of the compressor.
Versatility
PUWU’s biggest selling point is its 5-in-1 capability — combining MIG, TIG, Stick, and Plasma cutting in a single compact unit. This makes it a great choice for welders who frequently switch between processes but don’t want multiple machines cluttering their space.
It’s particularly handy for small shops or contractors doing automotive repair, light fabrication, and maintenance work. The Lift TIG function also allows smoother starts without tungsten contamination, while the Gasless MIG option gives flexibility for outdoor welding where shielding gas isn’t practical.
Build Quality and Design
The metal body with black plastic trim feels robust yet lightweight. PUWU has done well to ensure durability without making the machine bulky. The interior components are neatly assembled, and the cooling vents are strategically placed to prevent overheating during prolonged sessions.
The overall design is clean — with a clear digital display and easy-to-reach control knobs. The labeling is straightforward, which makes it beginner-friendly while still offering enough control for experienced welders.
Ease of Use
The PUWU combo is designed for plug-and-play simplicity. The digital interface makes adjusting current and voltage intuitive, while the quick connectors minimize setup time when changing processes.
The included accessories — from welding torches to hoses and clamps — mean you don’t have to run out and buy extras before starting. The machine also includes a conversion cable (220V to 110V), making it travel-friendly between home and job sites.
Portability
Weighing only 25.6 pounds, this machine is considerably lighter than many other multi-process welders. The compact frame makes it easy to carry around, yet it doesn’t compromise on performance.
For welders who move between projects, the PUWU CT-418PRO offers a rare balance between power and mobility.
Price and Value
Given its capabilities, the PUWU combo offers excellent value for its price range. It combines the functionality of five machines — MIG, TIG, Stick, and Plasma Cutter — in one unit, often priced lower than standalone MIG or TIG welders.
Considering it comes with multiple torches, cables, connectors, and hoses, the overall package feels generous. It’s an appealing buy for welders on a budget who don’t want to sacrifice versatility.

What to Know Before Buying
Before you invest in the PUWU combo, here are a few things to keep in mind.
Power and Voltage Considerations
This welder operates seamlessly on both 110V and 220V, but you’ll only unlock its full power (200A MIG) on 220V. For lighter fabrication and home repairs, 110V operation is perfectly fine, though slightly limited in penetration depth.
Aluminum Welding Capability
Unlike many budget machines, the PUWU supports aluminum welding through its Gas MIG mode. You’ll need an optional spool gun for best results, but its arc smoothness and feed stability make it viable for soft aluminum wires.
Plasma Cutting and TIG Arc Control
The PT31 plasma torch allows quick, efficient cuts with minimal dross. While it doesn’t match industrial-grade cutters, it’s ideal for most shop projects. The Lift TIG feature offers clean starts without tungsten sticking — a great inclusion for stainless or thin metals.
Accessories and Setup
PUWU’s accessory kit is one of the most comprehensive you’ll find at this price. It includes three torches, hoses, clamps, a regulator, and conversion cables, all securely packed with anti-suffocation nylon wrapping.
Limitations to Keep in Mind
This is not a machine built for long, heavy-duty cycles. If you’re running continuous welds for hours daily, a commercial-grade setup might serve you better. However, for light fabrication, maintenance, and auto repair, it’s more than capable.
Best Features
1. 5-in-1 Multi-Process Capability
The standout feature — a single machine that covers MIG (Gas & Gasless), Lift TIG, Stick, and Plasma Cutting. It gives complete flexibility for varied materials and environments.
2. Dual Voltage Flexibility
The 110V/220V dual input makes it compatible with both household outlets and industrial power supplies. You can work anywhere — garage, shop, or field.
3. Digital Display and Control Panel
Though basic, the digital interface helps maintain precise control over welding parameters. Current adjustment is smooth, and readouts are clear even in bright light.
4. High-Frequency Start and Cutting
The machine uses high-frequency (HF) arc start, which improves ignition reliability in both TIG and Plasma modes. It reduces electrode contamination and offers faster starts.
5. Complete Accessory Package
Every process is covered out of the box. The 3 m MIG gun, 4 m PT31 torch, and 4 m TIG gun give ample reach, and the included hoses, clamps, and connectors reduce setup hassle.
6. Build and Design Quality
The sturdy chassis, lightweight frame, and five-layer aircraft-grade packaging ensure durability and safety during shipping. Every unit is serialized — a rare touch in this category.
Alternatives in This Range
To give perspective, let’s compare the PUWU 5-in-1 Combo with two other popular multi-process units — the HITBOX CT520 and the YESWELDER FIRSTESS MP200.

Final Thoughts
The PUWU Plasma Cutter Welder Combo CT-418PRO is one of the most well-rounded and affordable 5-in-1 welding solutions available. It blends power, precision, and portability in a way that makes it attractive for both hobbyists and professional welders seeking flexibility without the bulk of multiple machines.
It’s not built for heavy industrial use, nor does it have advanced TIG pulse settings or memory storage — but for the price, it’s an incredibly practical, value-packed, and capable piece of equipment.
If you’re a welder who wants to cut, weld, and repair various metals — from mild steel to aluminum — using a single, portable setup, the PUWU CT-418PRO is definitely worth considering.
