The Hobart 195158 Handler 125 MIG Gas Conversion Kit is designed to convert Hobart s original flux-cored wire feeders (like the Handler 125) to run with standard MIG wire, allowing for smoother operation and better weld quality. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Hobart 195158 MIG Gas Conversion Kit**
1. **Compatibility with MIG Wire** The original Handler 125 was designed for flux-cored wire, which doesn t require shielding gas. This kit enables the use of solid MIG wire, which often produces cleaner, stronger welds with better appearance and less spatter.
2. **Improved Weld Quality** MIG wire (especially ER70S-6) generally provides better penetration, smoother deposits, and less porosity compared to flux-cored wire, making it ideal for structural, automotive, or precision welding applications.
3. **Versatility** The ability to switch between flux-cored and MIG wire (with the original setup) gives the Handler 125 greater flexibility for different projects. This is particularly useful for welders who work on both thin and thick materials or need to match specific wire types for contracts.
4. **Better for Thin Materials** MIG wire is less likely to cause burn-through on thinner metals (e.g., sheet metal, aluminum alloys) compared to flux-cored wire, which can be more aggressive.
5. **Reduced Spatter** While flux-cored wire is forgiving for outdoor or dirty conditions, MIG wire with proper gas shielding produces significantly less spatter, leading to cleaner workpieces and less cleanup.
6. **Compatibility with Gasless MIG Options** If you later decide to use self-shielded MIG wire (e.g., ER70S-6 with a flux coating), the Handler 125 can still function without additional gas, though performance may not be as refined as with standard MIG.
7. **Cost-Effective for Some Applications** For certain projects (e.g., structural steel, automotive bodywork), MIG wire can be more cost-effective than flux-cored, especially if you re buying wire in bulk.
8. **Easier to Use for Beginners** MIG welding is often considered more beginner-friendly than flux-cored due to its consistent arc and easier control of heat input.

### **Cons of the Hobart 195158 MIG Gas Conversion Kit**
1. **Requires Shielding Gas** Unlike flux-cored wire, MIG wire requires a constant supply of shielding gas (e.g., CO , argon-based mixes). This adds cost (gas cylinders, regulators, hoses) and complexity, especially if you re not already set up for gas welding. Outdoor or high-wind conditions can also disrupt the gas shield, leading to poor welds.
2. **Higher Initial Cost** While the conversion kit itself is relatively affordable, you ll need to invest in shielding gas, gas cylinders, and possibly additional accessories (e.g., gas flow meters, hose kits) if you don t already have them.
3. **Maintenance of Gas System** Gas cylinders and regulators require periodic checks for leaks, and improper gas flow can ruin welds. This adds maintenance overhead compared to flux-cored welding, which is more forgiving.
4. **Limited Portability** Carrying gas cylinders can be cumbersome, especially for field work or job sites without gas access. Flux-cored welding is more portable since it doesn t require gas.
5. **Potential for Overhead Costs** If you re welding frequently, the cost of gas and wire can add up. While MIG wire is often cheaper per pound than flux-cored, the gas adds an ongoing expense.
6. **Learning Curve for Gas Adjustments** Proper gas flow rate and type (e.g., 75% Argon/25% CO vs. pure CO ) significantly affect weld quality. Beginners may need to experiment to find the right settings, which can be frustrating.
7. **Not Ideal for Outdoor or Windy Conditions** Gas shielding is easily disrupted by wind, leading to incomplete protection and poor welds. Flux-cored wire is more tolerant of such conditions.
8. **Potential for Overkill for Simple Projects** If you re primarily welding scrap metal, farm equipment, or other low-tolerance applications where flux-cored wire works fine, the added complexity of MIG may not be justified.

### **Conclusion**
The Hobart 195158 MIG Gas Conversion Kit is a worthwhile upgrade if you:- Need the precision, cleanliness, and strength of MIG wire for structural, automotive, or high-quality welding.
- Already have or are willing to invest in a gas system (cylinders, regulators, hoses).
- Work in controlled environments where gas shielding isn t disrupted by wind or drafts.
- Want the flexibility to switch between flux-cored and MIG wire as needed.
However, if you:- Primarily weld in outdoor or high-wind conditions.
- Don t want the hassle of managing gas cylinders.
- Are on a tight budget and mostly work with flux-cored wire.
- Prefer the simplicity of gasless welding.
...then the conversion may not be necessary, and the original flux-cored setup could suffice.

### **Recommendation**
**Buy the Hobart 195158 MIG Gas Conversion Kit if:**- You re already using the Handler 125 for flux-cored work and want to expand its capabilities for MIG applications.
- You have or plan to set up a gas system (e.g., for other welding projects).
- You frequently weld materials where MIG wire offers clear advantages (e.g., thin gauge metals, structural steel, or projects requiring smooth, clean welds).
- You value versatility and don t mind the added responsibility of managing gas.
**Skip the conversion if:**- You re happy with the Handler 125 s flux-cored performance and don t need MIG wire.
- You weld mostly outdoors or in windy conditions where gas shielding is unreliable.
- You re on a tight budget and can t justify the cost of gas and additional equipment.
- You re a beginner and prefer the simplicity of flux-cored welding.
**Alternative Consideration:**If you re unsure, test both setups on a few projects. Hobart s Handler 125 is a solid machine, and the conversion kit is relatively inexpensive. If you find yourself needing MIG wire frequently, the upgrade will pay off. Otherwise, stick with flux-cored for its convenience.
