Can a power station run a welder?

Power tools Also called: welder, stick welder, MIG welder

Two numbers decide whether a power station runs a welder (stick / MIG), and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — this load needs 2,700 W of them while it runs. Watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.

Of the 26 station records we publish — every model we hold a page for, with its US and EU versions counted separately — 2 run it, 0 are a tight fit and 24 are out of reach. Each of those is a calculation against that machine’s continuous output, its surge ceiling and its inverter waveform — not a lookup table — and the reasoning is on every row.

The three numbers a power station is judged against

Running power 2,700 W 2,300–11,500 W Official spec · verified 2026-08-01 · medium confidence

Start-up surge Not found in the sources we checked no figure to date

Duty cycle 30% Official spec · verified 2026-08-01 · high confidence

The band is the spread across real models in this class, not a tolerance. Size against the top of it unless you know which unit you own.

Start-up figure: No start-up figure found

We have found no published start-up figure for this class. This library does not invent one: where a start-up check is required, the engine caps the verdict below green rather than assuming the machine starts cleanly.

Two ways to read a duty cycle

A duty cycle can be read two ways and they are not the same number. One is the constant a test procedure assumes so that a label figure is reproducible; the other is what the machine does in a real room, which depends on the weather, the door and the thermostat. This record keeps both ends: 20% to 30%, with the default above.

One figure on this record is disputed

The running power is escalated for manual adjudication: the manufacturer’s own specification sheet does not agree with itself, and no independent document exists to arbitrate between the readings on it. It does not flip a verdict, but it can move the order of the list below. Where a figure had to be chosen to carry on, this library took the more demanding reading, so any sizing guidance on this page is the worst-case one rather than the flattering one.

What actually decides it

A switch-mode supply: milliseconds, not seconds

A switching power supply charges its input capacitors at the instant it is connected, which can be a large current — but it lasts a few line cycles, two orders of magnitude shorter than the second-scale event a station’s surge rating describes. The two are not the same quantity and this site does not hold that spike against a verdict. What decides the outcome here is the steady draw, and where the power factor is poor, the VA the inverter actually sees behind it.

There is no start-up figure, and there should not be

Nothing here has a locked rotor to publish a figure for: a heating element, a switch-mode supply and a variable-speed drive all start without an inrush worth rating. The absence of a start-up number on this record is a fact about the hardware rather than a hole in the library, so the engine does not cap any verdict below for it — which is the opposite of what it does when a figure is genuinely missing.

Watts are not what the inverter is holding

At a power factor of 0.84 this load presents 3,214 VA to the inverter. An inverter is sold in watts and limited in volt-amps, so a machine that looks comfortable on the watt figure can be at its ceiling on the VA one. The engine checks both.

Which power stations run it

Every row is a live calculation against that machine's continuous output, surge ceiling and inverter waveform. Of the 26 station records we publish — US and EU versions counted separately — 2 run it, 0 are a tight fit and 24 are out of reach. The percentage is this load as a share of that machine's continuous output; anything past 82% drops out of the green. Rows are ordered by verdict, then by price — cheapest first inside each band.

Our pick for this load

EcoFlow DELTA Pro 3 · US 120 V

The cheapest US 120 V machine in the list that runs a welder (stick / MIG) outright, and it holds it at 810 Wh per hour.

Everything else we hold on this load

Each figure carries the tier it came from and the date it was checked. Sizing guidance is kept apart from measured draw on purpose: one says what the machine pulls, the other says what a manufacturer or a standard thinks you should buy for it.

Measured and published draw

Power factor 0.84 Official spec · verified 2026-08-01 · low confidence

The inverter is loaded to 3,214 VA — 2,700 W ÷ 0.84 — which is the figure its ceiling is actually measured against.

Sizing guidance — not a draw figure

Minimum continuous output 3,200 W Official spec · verified 2026-08-01 · medium confidence

A sizing figure, not a draw: it is what this class needs a machine to be RATED at, headroom included.

Where to go next

From the Knowledge channel

A welder (stick / MIG) has a dedicated guide: the same records this page computes from, worked through in prose with room for the reasoning a table can only summarise — Should you get a power station or a gas generator?

Questions people ask about this load

How many watts does a welder (stick / MIG) use?

2,700 W while it is running, and 2,300–11,500 W across the models in this class. Those are different questions and most pages answer only the first. The running figure decides whether a machine can hold it; the start-up figure decides whether it can get it going at all, and it is usually the one that fails. We have found no published start-up figure for this class.

What size power station do I need for a welder (stick / MIG)?

For a welder (stick / MIG), the EcoFlow DELTA Pro 3 (US 120 V) is the cheapest machine in our library that runs it, at 4,000 W continuous · 8,000 W surge ceiling and $2,799 against a running draw of 2,700 W. That is a verdict computed from this load’s running watts, its start-up demand and the inverter waveform — not a rule of thumb about doubling the wattage. 2 of 26 machines clear it.

How long will a power station run a welder (stick / MIG)?

We do not print one here, and the reason is in the rows rather than in our data. 10 of the 26 machines above hold everything the division needs — and every one of them is a machine that will not start a welder (stick / MIG), where an hour figure would be describing an hour that never happens. None of the machines that do run it prints one either: each of those rows names the published figure we could not find, rather than dividing a nameplate watt-hour rating by a label wattage, which runs typically 20–35% high.

Which power stations run a welder (stick / MIG)?

2 of the 26 we hold, listed above cheapest-first within each verdict band, starting with the EcoFlow DELTA Pro 3. The other 24 cannot run a welder (stick / MIG). Every one of those is a live calculation against that machine's own record, and opening a row shows the working.
