How Much Does It Cost to Run a Welder (MIG or Stick) in Canada? (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 C$0.56 per hour, or about C$4.20 per month at 0.25 hours a day in Canada (average). Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (2,000 W) | C$0.28 | C$0.070 | C$2.10 | C$25.55 |
| Typical (4,000 W) | C$0.56 | C$0.14 | C$4.20 | C$51.10 |
| High (7,000 W) | C$0.98 | C$0.25 | C$7.35 | C$89.43 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 365 kWh per year.
In Canada, with electricity at C$0.14 per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical welder (mig or stick) costs C$0.56 per hour and about C$51.10 per year at 0.25 hours a day. Each C$1.00 of electricity buys roughly 1.8 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 (C$12.26) 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.
