How to Set Up a Miller CP-302 to Weld Aluminum
The CP-302 is a metal inert gas (MIG) electric arc welding machine manufactured by the Miller Welding company. This machine is specifically designed for use in industrial and heavy industrial applications, such as automobile manufacturing, agricultural machinery repair and light metalwork fabrication. Although the standard configuration for the CP-302 is for welding carbon and stainless steel, it can also be converted to weld aluminum by installing a spool gun specially designed for feeding the softer aluminum MIG wire.
Things You'll Need
- Miller Welding 15A or 30A Spoolmatic kit
- Wire cutters
- Adjustable wrench
- Spool of aluminum MIG wire
