Buying Guide
Key purchase considerations
- TIG capability and process range: Decide if you need pure TIG, AC/DC TIG, or multi-process with TIG as a component. For aluminum work, AC TIG support and heat control are essential.
- Voltage and amperage: Evaluate your workspace power; 110V units are convenient for home garages, while 220V models offer higher amperage for thicker metals.
- Pulse and waveform options: Pulse helps manage heat input and bead quality on thinner or reactive metals. Some models also offer square or triangular waveforms for specialized control.
- Torch type and accessories: Flex-head or flexible-torch options ease access to tight joints. Some packages include a premium torch; check for hoses and consumables compatibility.
Metal type and joining considerations
- Aluminum welding benefits from clean AC TIG with adequate amperage; look for models with adjustable frequency and balance.
- Stainless and mild steel often weld well with DC TIG; consider a unit with stable arc control and good HF ignition for less sticking.
- Thin gauges require precise heat control; heavier sections benefit from higher amperage and robust duty cycle.
Power, portability, and durability
- Portability matters for on-site work; lighter units with integrated handles are ideal for field jobs.
- Durability and build quality influence long-term reliability in shop environments and outdoor settings.
- Consumables availability and accessory support can affect maintenance costs over time.
Practical use-case recommendations
- For aluminum-focused hobbyists: prioritize AC TIG capability, high-frequency start, and a flexible torch.
- For mixed-metal work or occasional MIG/MMA: a 3-in-1 or 7-in-1 machine can offer better value and flexibility.
- For portable fieldwork or small garages: balance weight, voltage options, and ease of use with a reliable display and synergy controls.
