Tech Specs:

Let’s take a look at the technical specifications that define the Weldpro MIG155GSV’s capabilities:

Performance:

Despite its compact size, the Weldpro MIG155GSV puts out up to 155 amps on 220V, delivering smooth, low-splatter MIG welds and reliable arc performance in FCAW and Stick modes. It welds 1/4” steel with ease on higher voltage and maintains solid puddle control even on 110V with thinner metal.

Processes:

• MIG (Gas-shielded): Very smooth arc, ideal for clean shop welds.

• Flux-Core (FCAW): Deep penetration, works well outdoors or on rusty/dirty metal.

• Stick (MMA): Accepts 1/16″, 3/32″, and 1/8″ rods. Excellent arc starts, works great with E6013, E7018, and E6011.

Portability:

At just 21 lbs, it’s ultra-portable — perfect for remote repairs, mobile welding trailers, and tight spaces. The handle and compact design make it easy to carry.

User Experience:

Setup is quick and painless. The dual control knobs allow for fast adjustment of voltage and wire speed, and the digital display provides accurate feedback for repeatable weld settings.

Pros and Cons:

Pros:

• Dual-voltage input with auto-sensing

• True multi-process: MIG, FCAW, and Stick

• Impressive duty cycle for its size

• Lightweight and compact (21.2 lbs)

• Stable arc performance on all modes

• Digital display for precision control

• 3-year warranty

• Easy to use for beginners

Cons:

• No support for TIG or spool gun

• Shorter ground clamp cable

• No memory or advanced waveform functions

• MIG gun not Euro-connect

• No adjustable burn-back or crater fill

What to Know Before Buying Weldpro MIG155GSV

The  Weldpro MIG155GSV is a value-packed machine — but it does have a few limitations you should consider before clicking “Buy.”

No TIG or Spool Gun Support:

This is a strictly MIG/Flux-core/Stick machine. It doesn’t offer TIG capability or a spool gun port, so if you plan to weld aluminum or thin stainless with TIG, look elsewhere.

Limited Advanced Settings:

There’s no burn-back control, crater fill, pre/post gas flow, or inductance settings. While fine for casual or light-duty work, more advanced users may find the control panel basic.

Short Ground Clamp Cable:

The ground cable is functional but short. This may limit mobility around larger projects unless you extend it.

Best Use Cases:

• Light fabrication

• Home repairs and farm work

• Automotive panel repair

• Beginner welding training

• Outdoor field work using FCAW

It’s not for heavy production or code-certified structural welding — but for 90% of DIY users, it’s more than enough.

Best Features of Weldpro MIG155GSV

Despite its limitations, the MIG155GSV offers some features rarely seen at this price point:

Multi-Process Support:

MIG, Flux-core, and Stick all in one box. No need to switch machines — just swap leads and change settings.

Dual Voltage Capability:

Runs on both household 110V and industrial 220V, automatically detects input and adjusts output. Perfect for remote job sites or garages.

Digital Display:

A clean, bright display shows real-time voltage and WFS settings, making repeatability much easier for beginner welders.

Arc Stability:

Excellent arc characteristics for the price — consistent, low-spatter starts on both MIG and Stick processes.

Value-Packed Accessories:

Comes with a gas regulator, MIG torch, electrode holder, ground clamp, and even a small spool of wire — ready to weld out of the box.

Alternatives in This Range:

If you’re shopping around this price point, here are two similar welders to compare:

Forney Easy Weld 140 MP:

• MIG/TIG/Stick capable

• 140A max output

• No digital display

• Great build quality and solid reputation

YESWELDER MIG-205DS:

• MIG/TIG/Stick support

• Up to 205A output

• Spool gun ready

• Higher duty cycle

• Slightly more complex interface

The Weldpro MIG155GSV is one of the most versatile, affordable, and portable welders in the sub-$250 range. If you’re a beginner, hobbyist, or someone needing a multi-process welder for light-duty tasks, this machine will get the job done without stress.

Sure, it lacks TIG or spool gun support, and it won’t win any awards for advanced control features — but for its simplicity, arc performance, and dual-voltage flexibility, the value is hard to beat.

Verdict: Highly recommended for entry-level and intermediate welders who want a budget-friendly workhorse for mild steel fabrication and stick repairs.
