Calculation Formulas

Heat Input (Q) = (V × I × 60) / (1000 × S)

Q = (V × I × 60) / (1000 × S)

Where:
V = Voltage (0 V)
I = Current (0 A)
S = Travel Speed (0 mm/min)

Q = (0 × 0 × 60) / (1000 × 0) = 0.00 kJ/mm

Current Calculation for MIG:

I = thickness × 40

I = 3 × 40 = 120 A

Voltage Calculation for MIG:

V = 14 + (I / 25)

V = 14 + (0 / 25) = 14.0 V

Travel Speed Calculation for MIG:

S = 300 - (thickness × 20)

S = 300 - (3 × 20) = 240 mm/min
