Buying Guide
What to consider when choosing a 240V welding setup:
- Power needs: Evaluate surge watts for welding machines and running watts for tools and lights. Choose a unit with more surge capacity than your peak load.
- Fuel flexibility: Dual‑fuel or tri‑fuel models offer contingency for fuel availability. Consider propane or natural gas options for longer outages.
- Transfer‑switch compatibility: If you plan to power a whole shop, ensure the generator supports a transfer switch and provides stable 120/240V output.
- Portability and space: Larger units provide more power but require more storage and handling space. Wheel kits help with mobility on job sites.
- Safety features: Look for CO detectors, automatic shutoff, and a stable, clean power output (low THD) for welding electronic loads.
