The Titanium MIG 140 Welder is a versatile machine that offers a wide range of welding capacities, including steel, stainless steel, and aluminum (with an optional spool gun). It also comes with a comprehensive set of accessories, including a MIG gun, flow gauge regulator, work clamp, and various drive rolls and gun consumables.

It is extremely lightweight and compact, making it ideal as a truck welder, and still has sufficient power for most common jobs.

I view it as great value for money based on its affordable price tag and construction quality.

Titanium 140 MIG Welding Machine
  • Tool-less Design
  • All-Metal Drive System
  • Lightweight and Compact
  • Inverter Power Source









  • Process: MIG and Flux Core
  • Dimensions: 15 x 19 x 8 inches
  • Weight: 26 pounds
  • Max Output: 140 amps
  • Output Range: 40-140A
  • Polarity: DC
  • Duty Cycle: 30% at 90A

I rate this as a medium-powered welder which can weld up to 1/4 inch steel, and is also inexpensive.

This lightweight design makes the machine highly portable and easy to move from one location to another, allowing it to be used in various settings, including job sites and workshops. The compact design makes the machine easy to store when not in use, taking up minimal space in your workspace.

PRO TIP: Ensure that you are using the appropriate wire feed speed for the material and thickness being welded. The welder's wire feed speed can be adjusted between 80 and 275 inches per minute, and selecting the correct wire feed speed is critical for producing high-quality welds. Using too high of a wire feed speed can lead to a weak and inconsistent weld, while using too low of a wire feed speed can cause the welding gun to stick to the workpiece and result in poor penetration.

What is Included?

  • Titanium MIG 140 Inverter Power Source
  • Titanium 180A MIG gun 10 ft.
  • Flow gauge regulator with 6 ft. gas hose
  • Work clamp with 10 ft. cable
  • 0.025 in., 0.030 in., 0.035 in. drive rolls
  • 0.030 in., 0.035 in. cored drive rolls
  • Gun consumables: 0.030 in. contact tips, gas nozzle, and gasless nozzle


  • Can Weld Steel, Stainless Steel, and Aluminium
  • 80 to 275 inches per minute wire feed speed
  • Extremely lightweight and inexpensive


  • 120V input only – no industrial voltage input
  • You need to purchase an additional spool gun to weld aluminum
  • Poor warranty
  • The duty cycle is low at 30% at 90 amps, so if you are working the machine hard at 140 amps, you will need to take a lot of breaks to avoid tripping the machine frequently on thermal overload.


1. Versatile Functionality

With an amperage range of 30 to 140A DC, this welding machine can handle various welding projects, from thin sheet metal to thicker materials up to 5/16 inch for steel and 3/16 inch for aluminum.

It is rare that you can buy a welder a this price that can weld this thickness and variety of metals.

The wire feed speed can be adjusted from 80 to 275 inches per minute, allowing greater control over the welding process.

2. Inverter Power Source

One of the standout features of the Titanium 140 Welder is its inverter power source, which provides a more stable and efficient arc compared to traditional transformer-based welders.

Inverter technology has significantly reduced the weight of modern welding machines, and this model is no exception. The more old-fashioned transformer power supplies are both heavy and bulky. The inverter also allows a higher frequency contributing to a more precise welding arc.

It also has thermal overload protection, ensuring safety and preventing damage to the machine in the event of overheating.

3. All-Metal Drive System

Unlike other welding machines that may use plastic components, the all-metal drive system ensures a consistent and steady wire feed, reducing the risk of feeding issues or wire jams that could affect the quality of the weld.

Additionally, the all-metal drive system is more durable and long-lasting than plastic components, making the machine less likely to experience mechanical failures or require frequent repairs.

This high-quality drive system indicates the overall build quality and attention to detail that has gone into the design of the Titanium MIG 140 Welder, making it a reliable and capable machine for a range of welding applications.

Field Testing

During field testing, I was surprised by the build quality of the Titanium 140. I expected lower-quality construction for its price tag, but it felt solid. Although compact and lightweight, it is still powerful enough to weld the majority of jobs that a DIY welding will see.

The handles on top make it extremely easy to transport, and I would likely keep this machine in my truck if I kept it permanently.

The digital controls are intuitive, even for beginner welders. Plus, the welder features a tool-free design to swap guns quickly and easily.






Value for Money


Overall Score


This machine is suitable for hobby welding and light shop welding. The lightweight design is ideal for welding in the field due to its portability and ease of direct transport to the job.

It has a poor 90-day defect warranty. This is very disappointing and shows that the manufacturer doesn’t have much faith in their design or workmanship.


If you intend to weld aluminum, then this is the spool gun you will need. This improves the welder’s versatility and gives you the ability to weld a much wider range of metals and jobs. It is comfortable to use in any position and requires no adapters.

It has a 10-foot-long cable, and is suitable for 0.030 to 0.035-inch wire.

Overall, the Titanium 140 Welder appears to be a reliable and versatile machine suitable for various welding projects. Its inverter power source and thermal overload protection make it a good choice for beginners and more experienced welders.

While it doesn’t have the same performance and durability as a premium Lincoln Electric Welder, it is great value for money and is well-suited for entry welders.

The main disadvantages are the low 140 amp power, and the limited duty cycle. For DIY welders this is likely suitable, but for welding shops or larger jobs this is just too small.
