Buying Guide: Key Purchase Considerations
- Welding Modes: Prioritize models offering AC TIG for aluminum and DC TIG for steel, plus pulse options to manage heat input and energy use.
- Voltage and Power: Dual voltage (110/220V) provides flexibility for home shops and pro shops. Check amperage range (e.g., up to 200A) for your typical material thickness.
- Waveforms and Control: Square and triangular pulse waveforms help reduce heat input; a good digital display simplifies setup and monitoring.
- Accessory Compatibility: Foot pedals, torches (like CK17), and built-in air compressors add versatility but may affect price and weight.
- Material Focus: Aluminum welding often benefits from AC TIG with high-frequency start; consider models with aluminum balance and lead control features.
- Safety and Protections: Look for VRD/overload protection, hot-start features, and soft-start capabilities to protect materials and equipment.
- Portability and Weight: Heavier machines may require dedicated workspaces; lighter units suit mobile setups but may have fewer features.
Across the selections, users should align a welder’s capabilities with anticipated projects—whether automotive fabrication, aluminum assemblies, or decorative metalwork. Consider future needs like expansion to heavier gauge metals or adding a spool gun for MIG aluminum when choosing a model.
