Set Wire Feed Speed for Spray Arc Transfer

What happens here

This is the core action of configuring the welder for spray arc transfer. The user rotates the 'Standard' control knob located on the front panel of the ARC CAPTAIN MIG 250 welder. This action directly adjusts the wire feed speed, measured in Inches Per Minute (IPM). The digital display dynamically updates as the knob is turned, cycling through various IPM values. The user begins by increasing the IPM from an implied initial lower value (around 134 IPM is briefly shown) to significantly higher settings, including 212, 218, 255, 269, 325, and briefly touching 360 IPM. The adjustment is then fine-tuned downwards to approximately 341 IPM. Throughout this precise calibration, the voltage setting remains constant at 20.3V, and the 0.035" wire diameter selection is maintained. This accurate setting of IPM is critical for achieving a stable spray arc transfer mode, which is commonly utilized in DIY fabrication for welding thicker materials (typically 1/8 inch or more) in flat or slightly horizontal welding positions, producing smoother, stronger welds with less spatter.

Goal: Achieve the correct wire feed speed (IPM) for spray arc welding
