Final answer:
Using spray arc transfer to weld stainless steel with a 0.045" electrode typically requires 26-32 volts and 180-280 amperes, although these settings can vary based on specific conditions.
Step-by-step explanation:
The student is inquiring about the parameters for spray arc transfer in Gas Metal Arc Welding (GMAW) or MIG welding. This process involves using certain voltage and amperage settings to effectively join stainless steel using a 0.045" (1.1mm) electrode. For spray arc transfer with a 0.045" (1.1mm) electrode for stainless steel, a common guideline is to use a voltage in the range of 26-32 volts and an amperage in the range of 180-280 amperes. However, these parameters can vary depending on the specific type of stainless steel, welding position, and joint configuration.
