Pre-Purchase Considerations
Before making a final decision, it’s important to understand the limitations and capabilities of the Champion 145. This machine is not suited for heavy industrial tasks but excels in light-duty applications where portability and fuel efficiency are priorities. Its power output is sufficient for welding up to 1/4 inch of mild steel, and it performs reliably within its specified duty cycle. Keep in mind that its auxiliary power support is limited when welding, so plan your workflow accordingly.
Power and Performance Limitations
The unit’s 145A capacity is ideal for small-scale projects but not intended for continuous heavy workloads. Its low duty cycle means it can operate for approximately 3 minutes at full amperage before needing a rest period. For tasks requiring sustained welding, a higher-capacity machine might be necessary. Additionally, the generator’s limited auxiliary power output means you cannot operate other tools simultaneously while welding without interruption.
Quality and Durability Concerns
While built with affordability in mind, some components like the transport wheels and fuel system may require attention or replacement over time. The absence of an electric start can be inconvenient, especially in cold environments. Users should also be aware of potential issues like carburetor icing and fuel leaks, which are documented in various forums and reviews. Nonetheless, with proper maintenance, the Hobart Champion 145 remains a reliable choice for light-duty welding tasks.
Adjusting the Amperage Control
The amperage adjustment knob is straightforward but can be confusing in practice. It features evenly spaced markers: min, 40, 100, 130, 140, and max. However, the equal spacing can make fine-tuning the amperage challenging, as small knob movements between certain points result in significant output changes. This requires users to be cautious and attentive when setting the desired amperage for precise welding results.
Advantages of the Champion 145
Outstanding Fuel Efficiency
This model is renowned for its economical fuel consumption. At maximum auxiliary power, it consumes roughly 0.7 gallons per hour, and about 0.5 gallons per hour during maximum welding operation. With a sizable 6.25-gallon tank, it can operate seamlessly throughout a workday, making it highly suitable for remote locations or prolonged projects without frequent refueling. Its energy efficiency stems from its modest power output, aligning perfectly with light-duty needs.
Quality Arc Performance
The Champion 145 provides a stable and manageable arc, making it easy for beginners to learn and for experienced welders to perform consistent welds. It handles 6010, 6011, 6013, and 7018 electrodes effectively, especially for welding up to 1/4 inch thick steel. The arc quality remains steady, and the unit’s reliability in starting and maintaining an electric arc is commendable, provided the electrodes are suitable and the machine is properly maintained.
Exceptional Portability
One of the most compelling features of this welder generator is its portability. Weighing just over 220 pounds, it is remarkably lightweight for a combination welding and power unit. Its compact dimensions and built-in wheels facilitate easy transportation across job sites, even for individuals with limited physical strength. This makes it an excellent choice for contractors, maintenance crews, or hobbyists who frequently move their equipment.
Comparative Analysis: Hobart Champion 145 vs Lincoln Bulldog
For those evaluating alternatives, the Lincoln Electric Bulldog offers a comparable option but with notable differences. While the Lincoln features a Kohler engine, which is often considered more durable, it operates on AC as opposed to DC, and weighs slightly less at approximately 198 pounds. However, it comes at a higher cost and lacks support for running gear. Moreover, the Lincoln’s lower duty cycle and slightly different power specifications mean it may not be ideal for all applications. Here’s a comparative overview:
| Hobart Champion 145 | Lincoln Bulldog | |
|---|---|---|
| Welding Process | DC Stick | AC Stick |
| Maximum Electrode Size | 5/32 inch | 1/8 inch |
| Starting Method | Pull-start | Pull-start |
| Amperage Range | 40 – 145A | 70 – 140A |
| Duty Cycle | 30% at 130A | 30% at 125A |
| Generator Power | 4000W (peak 4500W) | 4000W (peak 5500W) |
| Mobility Support | Yes | No |
| Weight | 222 lbs | 198 lbs |
| Price Range | More Affordable | Higher Cost |
Final Thoughts
The Hobart Champion 145 stands out as a highly cost-effective, lightweight, and user-friendly welder generator tailored for light-duty applications. While it has certain limitations—such as a low duty cycle, absence of electric start, and limited auxiliary power support—it excels within its targeted use cases. Its portability, efficient fuel consumption, and reliable arc performance make it a practical choice for hobbyists, small contractors, and remote workers. If your workload exceeds its capabilities or you need more advanced features, exploring larger models like the Hobart Champion 260 or similar units might be advisable. Overall, the Champion 145 offers excellent value for its price and remains a popular choice among those seeking a versatile, manageable, and budget-friendly welding solution.
