How Much Does It Cost to Run a Welder (MIG or Stick) in Australia? (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 A$1.40 per hour, or about A$10.50 per month at 0.25 hours a day in Australia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 2,000 W | A$0.70 | A$0.17 | A$5.25 | A$63.87 |
| Typical 4,000 W | A$1.40 | A$0.35 | A$10.50 | A$127.75 |
| High 7,000 W | A$2.45 | A$0.61 | A$18.38 | A$223.56 |
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 Australia, with electricity at 35.0¢ per kWh (source: AER Default Market Offer 2026–27, 2026-07), a typical welder (mig or stick) costs A$1.40 per hour and about A$127.75 per year at 0.25 hours a day. Each A$1.00 of electricity buys roughly 0.7 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 (A$30.66) 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.
