How Much Does It Cost to Run a Welder (MIG or Stick) in Indiana? (2026)
Welders draw heavy current while the arc is on, from 2 kW for a small MIG at low settings to 7 kW or more for a stick welder at full output. Arc-on time is a small fraction of shop time, so total energy is modest.
A typical welder (mig or stick) (4,000 W) costs $0.70 per hour, or about $5.25 per month at 0.25 hours a day in Indiana. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 2,000 W | $0.35 | $0.088 | $2.63 | $31.96 |
| Typical 4,000 W | $0.70 | $0.18 | $5.25 | $63.91 |
| High 7,000 W | $1.23 | $0.31 | $9.19 | $111.85 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 365 kWh per year.
One hour of a welder (mig or stick) (4.0 kWh) is the same electricity as
- 22km in an electric car
- 40hours of TV
- 89hours of a laptop
- 444hours of an LED bulb
In Indiana, with electricity at 17.5¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical welder (mig or stick) costs $0.70 per hour and about $63.91 per year at 0.25 hours a day. That is about 5% less than the national average for the US ($5.50 per month), because electricity in Indiana costs 17.5¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 1.4 hours of use.
How to lower the cost of running a welder (mig or stick)
- Turn the welder off between jobs. Transformer welders draw 10 to 30 watts idle.
- Use the lowest amperage that gives good penetration.
- Inverter welders are 20 to 30 percent more efficient than transformer types.
In standby it draws about 10 W, which adds roughly 88 kWh ($15.34) per year if it is never unplugged.
Frequently asked questions
How much electricity does a welder use per hour of welding?
About 4 kWh per hour of actual arc time on a typical machine. Real sessions have far less arc time.
Do welders use power when idle?
Transformer welders draw 10 to 30 watts idle; inverters use less.
Is a 240 V welder more expensive to run?
No. Voltage affects available power, not efficiency.
