Looking for: Mig definition top gun Click here to ENTER Mig definition top gun If you weld aluminum or stainless steel, for example, you will find that it reflects more heat than mild steel. The shielding gas mixture you use, as well as the welding transfer process, can also affect radiant heat. For example, argon creates a hotter arc than pure CO2, causing a MIG gun using an argon shielding gas mixture to reach its rated temperature at a lower amperage than when welding with pure CO2. If you use a spray transfer process, you may also find that your welding application generates more heat. This process requires an 85 percent or richer argon shielding gas mixture, along with a longer wire stick out and arc length, both of which increase the voltage in the application and the overall temperature. The result is, again, more radiant heat. Using a longer MIG gun neck can help minimize the impact of radiant heat on the handle by placing it further from the arc and keeping it co
