To determine which brands and models of welders are compatible with specific covers, you need to consider the dimensions and design features of both the welder and the cover. Generally, welder covers are designed to fit specific models or a range of models from certain brands. Here are some popular brands and their compatible models:
1. **Miller Electric**: 
   - Compatible Models: Millermatic series (e.g., Millermatic 141, 211), Multimatic series, and Thunderbolt series.
   - Covers are often designed to fit specific models or a range of models within the same series.
2. **Lincoln Electric**:
   - Compatible Models: Power MIG series (e.g., Power MIG 210 MP), Square Wave TIG 200, and Ranger series.
   - Covers are typically tailored to fit the dimensions of these models.
3. **Hobart**:
   - Compatible Models: Handler series (e.g., Handler 140, 210 MVP), and Champion series.
   - Covers are usually made to fit the specific size and shape of these welders.
4. **ESAB**:
   - Compatible Models: Rebel series (e.g., Rebel EMP 215ic), and Sentinel series.

When selecting a cover, ensure it is made from durable, weather-resistant material to protect the welder from dust, moisture, and other environmental factors. Always check the product specifications for compatibility details, as some covers are universal and can fit multiple brands and models, while others are specifically designed for certain models.
