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 machines in our library, 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 published by the manufacturer 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 published start-up figure

Nobody publishes a start-up figure for this class, and 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: two manufacturer sources disagree and neither can be shown to supersede the other. 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 26 machines, 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.

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

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. Nobody publishes a start-up figure for this class, and this library does not invent one.

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 $2,399 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, 0 are a tight fit, and the tight ones are tight for reasons the list states individually.

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

It depends entirely on the machine, which is the part most pages skip. Against 2,700 W of running draw, our figures put the BLUETTI Elite 30 V2 at about 0.3 h, and the BLUETTI Elite 100 V2 at about 1.0 h. Those hours come from usable-capacity figures derived from the manufacturers’ own published depth of discharge and inverter efficiency, with each machine’s idle draw in the denominator — not from dividing a nameplate watt-hour number by a label wattage. Most machines in the list carry no hours at all: their brands publish nothing that makes a usable-capacity figure defensible, so those rows give an energy rate instead of a number we would have had to invent.

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. 0 more are a tight fit on a welder (stick / MIG) — they run it, but with less headroom than we are willing to call comfortable — and 24 cannot. Every one of those is a live calculation against that machine's own record, and opening a row shows the working.
