Choose a TIG welder based on the materials you intend to weld, the required output current, and whether AC capability is needed for aluminium — DC machines suit steel and stainless steel, while AC/DC machines offer greater versatility. When choosing a consumables supplier, look for consistent product quality, recognised standards, technical support and reliable stock availability.
How do you choose a TIG welder?
Choose a TIG welder based on the materials you intend to weld, the required output current, and whether AC capability is needed for aluminium. DC machines are suitable for steel and stainless steel, while AC/DC machines offer greater versatility. Also consider duty cycle, pulse functions and portability.
In short, work back from the job:
- Materials and current — steel and stainless steel need DC; aluminium needs AC, so an AC/DC machine is the most versatile. See our AC vs DC TIG welding guide.
- Output current — match the machine’s amperage range to your material thickness.
- Duty cycle — how long the machine can weld continuously before it needs to cool.
- Pulse functions — useful for thin materials and reducing distortion.
- Portability — important if you weld on site rather than in one location.
How do I choose a TIG consumables supplier?
Look for a supplier offering consistent product quality, recognised standards, technical support and reliable stock availability. A knowledgeable supplier can recommend the correct tungsten, filler rod and accessories for your application. Choosing the right consumables improves weld quality and reduces production downtime.
That technical support matters: getting the tungsten, filler rod and shielding gas right for each job is where a good supplier earns its place.
