Hello everyone. I need some information, I have AC/DC miller arc welding its just ordinary welding machine, have ac/dc connections in the bottom of machine, a rotating wheel for controlling amperage and power switch.
I want to convert it to TIG welding machine for aluminum weld, I know I can use it to weld in steel even without high frequency unit. My question is HOW ABOUT FOR ALUMINUM WELD? What do I need to buy in order to use it for aluminum. Do I need to buy they call it High Frequency Unit so I can able to weld in Aluminum or I need to buy something and what is it?. Pardon me I'm just new about in this welding field. Thanks all for help.
