Fume Dog Spot Welding Fume / Soldering Extractor

The Compact, Go-Anywhere Fume Extractor That's Built to Last a Lifetime.

The Fume Dog FD-PUP is a 350 CFM suitcase-style fume extractor designed for soldering, spot welding, and light-duty shop welding — built in the USA from 18-gauge steel, and powered by a brushless motor rated for 100,000 hours of continuous operation. At just 30 lbs and 62 dB, it's the professional-grade portable fume solution that's been missing from smaller shops, benchtops, and training environments.

However, this does not mean we do not have confidence in these products - in fact, the Fume Dog products come with a 10-year warranty on all major structural components.]

 Why the Motor Inside Actually Matters

Most compact fume extractors in this category look similar on the outside. The meaningful difference is what's running inside them.

The majority of suitcase-style and benchtop fume extractors use brush motors — the cheap, common motor configuration found in most low-cost portable units. Brush motors wear down over time as the carbon brushes erode against the rotor. Eventually the brushes need replacing. Most manufacturers know this, which is why you won't see "brush motor" prominently featured anywhere on their product pages — you'll usually find out after the unit has already started losing performance.

The FD-PUP uses a brushless motor rated for an average of 100,000 continuous duty hours. That's not a typo — it's a number that most competing motors can't come close to. In a shop running 8 hours a day, 250 days a year, that's approximately 50 years of motor life. In practice, the machine will long outlast its usefulness before the motor ever becomes the limiting factor. It's why the FD-PUP costs more than a cheap brush-motor alternative — and why it's cheaper in the long run.

350 CFM in a 30-Pound Package

350 CFM is the right airflow for what the FD-PUP is designed to do: capture fumes at the source during soldering, spot welding, TIG tacking, light MIG passes, and similar intermittent work. Position the self-supported arm 6 to 12 inches from your work, and the unit pulls fumes away before they reach your breathing zone.

A quick note on honest fit: the FD-PUP is not designed for 8-hour production welding shifts. If you need a machine for full-shift MIG or Stick welding, the Fume Dog PT (1,200 CFM) is the right tool. The Pup is for the bench welder, the solderer, the instructional environment, the shop that does intermittent light welding alongside other work. Knowing what a machine is designed for matters as much as knowing what it can do.

At only 30 lbs, it's genuinely portable — not "portable with a forklift" portable.

Two Carry Modes. One Machine.

Most portable extractors roll — and that's it. The FD-PUP is designed for two distinct modes:

Roll-Around Configuration: Heavy-duty casters let you roll the unit to wherever you're working in the shop, position it, and leave it running. The self-supported extraction arm holds its position once set — no hose flopping around, no re-adjusting between passes.

Suitcase Configuration: Flip the unit horizontal, use the built-in handle, and carry it like a suitcase to a different bay, a different floor, or out to a job site. At 30 lbs, one person handles it without issue.

This dual-mode design is what makes the FD-PUP especially well-suited for welding schools, training centers, vocational programs, and any environment where the machine needs to move between stations or rooms regularly.

Built for Shops That Take Safety Seriously

Welding and soldering fumes aren't just unpleasant. They contain fine metal particulates, metal oxides, flux gases, and in some applications, compounds like hexavalent chromium that carry real long-term health consequences. The FD-PUP captures fumes at the source — the only place they can realistically be controlled before they disperse into the room.

The unit is constructed from 18-gauge steel with a polyurethane powder-coat finish — not plastic. Near welding heat, spatter, and the general abuse of a working shop, steel is what holds up. Plastic warps, melts, and becomes a concern in an environment where the whole point is controlling a heat-related hazard.

It runs on standard 120V AC power at just 2.8 amps — a minimal draw that won't compete with your welder's circuit. It's also California Air Resources Board (CARB) certified, meeting one of the most stringent air quality standards in the country.

At 62 dB, it's quiet enough that you won't be raising your voice over it. A shop conversation stays a shop conversation.

Frequently Asked Questions about Fume Dog Spot Welding Fume / Soldering Extractor

Q: What's the FD-PUP actually designed for?

A: Soldering fume extraction and light-duty welding — spot welding, TIG tacking, short MIG passes, and similar intermittent work. It delivers 350 CFM of source-capture airflow, which is appropriate for these applications. It is not designed for production welding — continuous shift MIG, Stick, or flux-core work requires the Fume Dog PT (1,200 CFM). If you're unsure which unit fits your use case, contact our team before ordering.

Q: What makes the motor different from cheaper units?

A: The FD-PUP uses a brushless motor rated for an average of 100,000 continuous duty hours. Most competing suitcase and compact fume extractors use brush motors, which wear over time and require brush replacement — a maintenance burden that manufacturers rarely advertise clearly. A brushless motor has no brushes to wear, runs cooler, and lasts dramatically longer. This is the main reason the FD-PUP costs more than budget alternatives — and the main reason it's the better long-term value.

Q: How heavy is it and how does it carry?

A: 30 lbs — light enough for one person to carry comfortably. The unit has two configurations: upright on casters for roll-around shop mobility, and horizontal in a suitcase carry mode using the built-in handle, for moving between stations, rooms, or job sites.

Q: How loud is it?

A: 62 dB — roughly equivalent to normal conversational noise. It won't require hearing protection near the machine and won't prevent normal communication in the shop during operation.

Q: What power does it require?

A: 120V AC, single phase, 60 Hz — standard shop outlet power. It draws only 2.8 amps at 350W, so it won't compete with your welder's circuit.

Q: Is it CARB certified — and why does that matter?

A: Yes, the FD-PUP is California Air Resources Board (CARB) certified — one of the most stringent air quality certifications in the United States. CARB certification confirms that the unit meets emissions and performance standards that go beyond typical federal requirements. Whether you're in California or not, this certification is a meaningful indicator of build quality and filtration performance.

Q: How close does the arm need to be to my work?

A: For best results, position the extraction hood 6 to 12 inches from the weld or solder point, angled slightly upward to intercept rising fumes before they reach your breathing zone. The self-supported arm holds its position once set, so you don't need to readjust between passes.

Q: Is this appropriate for a welding school or training environment?

A: Yes — the FD-PUP is particularly well-suited for welding schools, vocational programs, and training centers. It's light enough for students to move between stations, quiet enough for instruction to happen over it, and built from steel that holds up to daily institutional use. Its suitcase carry mode makes it easy to relocate between classrooms or storage areas.

Q: What's the difference between the FD-PUP and the Fume Dog PT?

A: The FD-PUP is a 30 lb, 350 CFM suitcase-style unit for soldering and light intermittent welding. The Fume Dog PT is a ~250 lb, 1,200 CFM production unit with a 10-foot articulating arm, multi-stage HEPA + carbon filtration, and a built-in filter cleaning system — designed for one to two full shifts of MIG, TIG, or Stick welding daily. If you weld continuously for hours at a time, the PT is the correct tool. If you solder, spot weld, or weld occasionally in shorter sessions, the Pup is the right fit.

Q: What is the Returns Policy on the Fume Dog?

A: Given the nature of how a fume extractor is used, it is no longer a "new" product after first use, given contaminants which enter the filtration system. As such, Fume Dog products are an exception to The Maker's Chest returns policy, and all sales are final.

However, this does not mean we do not have confidence in these products - in fact, the Fume Dog products come with a 10-year warranty on the major structural components of the goods, provided the products are properly installed, maintained, and operated under normal conditions.
