Page 19: Fan Control
The arc force is important in determining how the current changes in response to a change in the arc length. A lower value gives a calmer arc with less spatter. It only applies to MMA welding. 0463 730 231 - 19 - © ESAB AB 2022... - Page 20 For GMAW and self shielded core wire welding, the power source shall be supplemented with: • wire feed unit • welding torch • connection cable between power source and wire feed unit • gas cylinder • return cable with clamp 0463 730 231 - 20 - © ESAB AB 2022...

Page 21: Shielding Gas Recommendation
A general rule to be followed for shielding gas flow rate is 10 to 12 times of wire size. It may increase for different welding applications where higher stick out and parameters are used. When using Helium mixtures, the flow rate must be 1.5 to 3 times more than with argon. 0463 730 231 - 21 - © ESAB AB 2022... -
