I use argon for TIG and a bottle lasts a good while. Argon or Argon/Helium works well with most metals including aluminum. If you buy a used bottle, check for a date stamp on the side. Over here in the States, bottles are supposed to be hydraulically tested every 5-7 years. The welding shop will hit you up for a extra charge if you bring an outdated bottle. -Dick |

Over here the bottles need checking every 10 years. I have tried strait Argon when I was desperate for mig welding steel, and while it works, you get a cold weld so it's not suited. Dave |
