Free welding calculator for MIG, TIG, Stick & Flux-Cored processes. Calculate optimal current, voltage, travel speed & heat input based on material thickness instantly.
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
