Q: What makes a TIG welder suitable for aluminum and stainless steel?

A: A TIG welder with both AC (alternating current) and DC (direct current) options is ideal. Aluminum welding typically requires AC due to its oxide layer, whereas stainless steel is best welded with DC.

Q: Why is pulse function important in a TIG welder for these materials?

A: Pulse welding helps control heat input, making welding thin materials like aluminum and stainless steel easier without warping or burning through.

Q: Can aluminum and stainless steel use the same tungsten electrode?

A: While possible, it’s recommended to use pure tungsten for aluminum and thoriated or created tungsten for stainless steel for best results.

Q: How do I know the correct amperage setting for different metal thicknesses?

A: Most welders come with a manual that provides a guideline. However, a general rule is to use 1 amp for every 0.001 inch of material thickness.

Q: Is a foot pedal necessary for TIG welding aluminum and stainless steel?

A: While not necessary, a foot pedal provides better control over the amperage, especially for intricate or detailed work on these materials.

Q: How important is the duty cycle in a TIG welder when working with aluminum and stainless steel?

A: The duty cycle indicates how long you can weld before needing a rest period. For continuous welding on thick sections of aluminum or stainless steel, a high-duty process is advantageous.

Q: Can I use the same shielding gas for aluminum and stainless steel?

A: Argon is commonly used as a shielding gas for both materials. However, a mix of argon and a small percentage of carbon dioxide or helium can sometimes provide better results for stainless steel.
