The Industrial Welding Fume Extractor That Actually Travels With You.
The Fume Dog PT delivers 1,200 CFM of fume extraction power in a heavy-duty steel unit that rolls to wherever you're welding — and converts to a wall-mounted collector without buying a single additional accessory. Built for MIG, TIG, and Stick welding across one to two shifts a day, it's the portable fume solution that doesn't make you choose between mobility and performance.
[Return Policy exception: Fume Dog products are an exception to The Maker's Chest standard 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 all major structural components.]
Why Welding Fume Extraction Actually Matters
Welding fumes aren't just unpleasant — they're a genuine long-term health hazard. Fumes from MIG, TIG, and Stick welding contain fine metal particulates, metal oxides, and in some applications (like stainless steel), hexavalent chromium — a known carcinogen. OSHA has established permissible exposure limits for these contaminants, and the answer to staying under them isn't better ventilation. It's source capture: pulling the fume directly at the point of generation before it ever reaches your breathing zone.
General shop ventilation improves overall air quality — but you can have an open bay and still be breathing concentrated fume right at the weld puddle. A fume extractor positioned with the arm 6 to 12 inches from the weld is the difference between clean air and cumulative exposure.
1,200 CFM — And the Arm to Match It
Most fume extractors list a CFM number. What they don't always tell you is whether their arm can actually move that air.
The Fume Dog PT uses an 8" diameter, 10-foot articulating arm — the right pairing for 1,200 CFM performance. A 6" arm at that airflow is a mismatch that kills capture efficiency and causes pressure drop. The 8" arm maintains effective suction draw up to approximately 18 inches from the weld, giving your welder real working room without needing to constantly readjust the arm between passes.
The arm articulates to hold position once set — no constant repositioning between weld runs. An optional dual-arm configuration is also available for two-station setups.
Three-Stage Filtration: Built to Catch What You Can't See
The Fume Dog PT uses a multi-stage HEPA + activated carbon filtration system designed to handle the full range of weld fume hazards:
Stage 1 — Pre-filter: Catches larger particles and weld spatter before they reach the primary filter, extending the life of your main HEPA element.
Stage 2 — HEPA filter: Captures 99.97% of particles down to 0.3 microns — the size range where fine metal fumes, metal oxides, and respirable particulates live. Required for hexavalent chromium control when welding stainless steel.
Stage 3 — Activated carbon filter: Absorbs gases, ozone, nitrogen oxides, and odors that particulate filters alone can't touch. Especially important when welding galvanized, coated, or stainless materials.
The built-in Air Stream Filter Cleaning System extends filter life 5 to 6 times longer than traditional reverse-pulse systems — which means dramatically fewer filter change intervals and lower ongoing maintenance costs.
One Machine. Three Configurations.
Most fume extractors are built for one use case. The Fume Dog PT is built for however your shop works.
Floor-Mounted Portable: The standard configuration. Heavy-duty caster wheels roll the unit between welding stations, to different bays, or out of the way when not needed. At roughly 250 lbs., it's a serious machine — but the casters make it genuinely movable by one person.
Wall-Mounted Collector: The unit converts from portable to wall-mounted out of the box, with no additional accessories required. If you have a dedicated welding bay and want to reclaim floor space, the same machine mounts to the wall without any extra hardware or modification. The video in the product gallery shows exactly how it's done.
Downdraft Table: With an optional accessory (sold separately), the Fume Dog PT converts to a downdraft table configuration — pulling fumes downward through a perforated surface as you weld on top. Three tools in one machine.
Built Like a Shop Tool, Not a Consumer Product
Welding environments are hard on equipment. Heat, spatter, metal dust, and physical contact are daily realities. The Fume Dog PT is constructed from heavy-duty powder-coated steel — not plastic. This matters for one obvious reason: plastic and heat are a bad combination in a welding shop. The steel housing handles the environment, resists physical damage, and doesn't become a fire concern the way plastic units can.
The casters are heavy-duty shop-grade, rated for real production movement — not the lightweight wheels found on consumer-facing units that wobble under load.
The Filter Cost Problem — and Why Fume Dog Solves It
Here's something most fume extractor manufacturers don't advertise: replacement filters for many units are proprietary and marked up aggressively — sometimes $400 to $600 for a single filter cartridge you can only get from one source.
The Fume Dog PT uses standard-size replacement filters available from multiple suppliers. You're not locked into a single-source filter monopoly. Pre-filters typically need replacement every 1 to 3 months depending on use. The HEPA main filter, thanks to the Air Stream Cleaning System, lasts significantly longer than competing units — and when it does need replacing, you're buying a standard filter at a market price, not a proprietary one at a premium.

Frequently Asked Questions about Fume Dog Portable Weld Fume Extractor
Q: What welding processes does the Fume Dog PT work with?
A: It's designed for MIG, TIG, and Stick welding — the three most common shop welding processes. The 1,200 CFM airflow and HEPA + carbon multi-stage filtration handle the fume characteristics of all three. It is not recommended for plasma cutting or carbon arc gouging, which produce higher volumes of particulate and sparks that can damage filter media.
Q: How close does the extraction arm need to be to my weld?
A: For optimal capture, position the 8" hood 6 to 12 inches from the weld puddle, angled slightly to intercept rising fumes before they reach your breathing zone. The 1,200 CFM airflow and 8" arm diameter maintain effective suction draw at up to approximately 18 inches — but closer is always better for capture efficiency.
Q: Does it really convert to a wall mount with no extra accessories?
A: Yes. The Fume Dog PT ships with everything needed to convert from floor-mounted portable to wall-mounted collector. No additional hardware or accessories are required. The product gallery video demonstrates the conversion process step by step.
Q: What is the Air Stream Filter Cleaning System and how does it work?
A: It's a built-in filter cleaning mechanism that uses a controlled air stream to dislodge captured particulate from the filter media — extending filter life 5 to 6 times longer compared to traditional reverse-pulse cleaning systems. This translates directly to fewer filter change intervals and lower maintenance cost over time, which is significant for a unit running one to two shifts daily.
Q: Will the replacement filters be expensive or hard to find?
A: No — this is one of the Fume Dog PT's deliberate design advantages. The unit uses standard-size replacement filters available from multiple suppliers at competitive market prices. You are not locked into proprietary filters from a single source. Pre-filters typically run 1 to 3 months between changes; the HEPA main filter lasts considerably longer with the cleaning system active.
Q: Is it safe for welding stainless steel?
A: Yes. The HEPA filter stage captures particles down to 0.3 microns at 99.97% efficiency, which is the required filtration level for hexavalent chromium — the carcinogenic compound produced when welding stainless steel. The activated carbon stage additionally handles the gases and ozone associated with stainless welding. For regular stainless steel production, this is the appropriate filtration level.
Q: Can one unit handle two welding stations?
A: The standard PT ships with a single 10-foot articulating arm. An optional dual-arm configuration is available if you need to serve two adjacent welding stations from one unit. Contact us before ordering if you want to configure the dual-arm setup — we can help you determine if it's the right fit for your station layout.
Q: What's the noise level like?
A: The Fume Dog PT is designed for shop-safe sound levels — it operates quietly enough to allow normal conversation and communication in the shop during operation, unlike some high-CFM units that require hearing protection near the machine.
Q: What power does it require?
A: Standard 120V AC power — the same outlet available in virtually any commercial or industrial shop setting. Other voltages are available; contact us if your facility operates on a different voltage standard.
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.
