Manufacturer overview

The FIRMAN WT06375 Inverter Generator answers the call with a peak of 7850 starting watts and 6300 running watts on gasoline (7100/5700W on LPG, 6100/4900W on natural gas). This tri-fuel generator offers unmatched flexibility and performance. Run it on gas, propane, or natural gas, whichever suits your needs best. Powered by a durable 322cc FIRMAN engine with a cast-iron sleeve, the WT06375 delivers clean, stable inverter power, perfect for sensitive electronics, job site tools, and backup home appliances. Start it effortlessly with the electric start or use the recoil backup when needed. It operates at a quiet 67 dB (¼ load) and features a 120/240V output, making it RV-ready and storm-ready. The outlet panel includes a 20A 120V GFCI (5-20R), 50A 120/240V (14-50R), 30A 120V RV (TT-30R), 30A 120/240V twist-lock (L14-30R), and even USB-A and USB-C ports for direct device charging. With a 5.3-gallon tank and up to 16 hours of runtime at 25% load, the WT06375 is designed for endurance. Safety comes standard with CO Alert shutoff, spark arrestor, and low-oil shutdown. Its compact 132-lb frame is paired with 8” flat-free wheels and a folding U-handle, making it portable for its class. The WT06375 comes with an engine oil bottle, an oil funnel, a tool kit, an LPG regulator, an Owner's Manual, a Quick Start Guide, and a quick oil drain.

Controlled conditions

Record the exact model, serial number, firmware, sample source, and test date before any measurement.
Log ambient temperature, humidity, elevation, wind, surface, and background sound for every test block.
Record instrument model, range, accuracy, and most recent calibration or verification date.
Repeat timing, starting, and sound measurements three times when conditions allow; publish every valid run.
Keep original notes, load logs, meter exports, photos, and any excluded-run explanation with the result.

Safety gate

Operate fuel-burning equipment outdoors only, far from occupied structures, openings, and ignition hazards, with working carbon-monoxide monitoring for personnel.

Testing is for qualified personnel using correctly rated load equipment and the manufacturer’s required grounding, bonding, clearance, and protective-device instructions.

Never connect a generator directly to building wiring or bypass overload, temperature, battery, GFCI, or carbon-monoxide shutdown protection.

Stop a run for unstable voltage or frequency, overheating, fuel or electrolyte leakage, abnormal sound, damaged wiring, or any manufacturer fault indication.

Badge rule: this product receives no “FMG Tested” label or score benefit until a real unit, instruments, conditions, valid runs, raw records, and limitations are documented under the public protocol.
