Your Welding Shop’s Too Smoky — And Your Welders Know It

You walk through your shop and the haze sits right at eye level. A box fan pushing it sideways. The roll-up cracked open. Your guys waving smoke out of their face between welds. You’ve seen it every day for years. Most days you don’t even notice anymore.

Other people notice. Your best welder notices. The new guy you tried to hire last month — the one who walked through, looked around, and didn’t call back — he noticed too.

This isn’t an article about OSHA. We’ll get to that briefly at the end. This is about the cheapest, simplest move you can make this month — no big system, no rewiring the shop, no shutting anything down — to start clearing the air your guys breathe and to show them you’re paying attention.

What the smoke is actually doing to your shop

Two things are costing you right now, and neither one is a fine.

Your guys are breathing it. Mild steel weld smoke carries iron oxide and manganese. Stainless adds hex chrome — the carcinogen California built a whole enforcement program around. Flux-core throws more smoke per inch of bead than anything else you run. Grinding fines are smaller and float further. By the end of the shift the guy on the bench has been pulling all of it into his lungs for eight hours. He won’t say anything. He’s used to it. That doesn’t mean it isn’t doing damage.

Welders know what good looks like, and they go to the shop that cares about them. Good welders aren’t easy to find anywhere right now. They’re harder to find in the Southwest. And it’s not just the veterans — the guys with ten, fifteen years on the gun who’ve worked clean shops and won’t go back to a smoky one. It’s the new guys too.

Every welding school and trade program in the country trains on extraction now. Every booth has an arm. That’s all the new welder coming out of school has ever seen. He walks into your bay, sees the fans and the open door, and his first thought isn’t “this shop is old school.” It’s “why doesn’t this shop have what my school had?” He’s already comparing you to his training program. You’re losing him on day one. He’ll keep looking — and every other shop in the valley is trying to hire him too.

So you’re squeezed from both ends. The veteran with options won’t come. The kid out of school won’t stay. The shop that runs smoky hires from the middle — the guys with nowhere else to go. That’s the worst pool you can build a fab business on.

One portable fume extractor on the worst station starts to fix this. Same day a unit shows up.

You don’t need a system. You need a start.

You hear “dust collection” and picture a $125,000 to $225,000 overhead with ductwork you’d have to rebuild the shop around. That’s what a real engineered system actually runs, and it’s the right answer for the right shop. But that’s not where most shops start.

A portable fume extractor is one rolling cabinet — about the footprint of a roll-around tool box — with an arm or a hose that hovers near the arc and pulls smoke before it hits your welder’s face. Plugs into a regular 120V outlet. Rolls on casters. Moves with the work. One unit on the worst station. Done.

Three units cover most Southwest fab shops. Pick by what your shop actually is:

If you need it this week: IAP Elevent

Sometimes a month-and-a-half is too long to wait. A welder’s about to quit. A contract starts Monday. Your best guy finally said something. For that situation we keep the IAP Elevent in our quick-ship lineup.

• $4,995 delivered. Published price, no haggling.
• Single-station portable, light-to-moderate welding
• Ships from stock — in your shop in days, not weeks

The Elevent’s a legit plug-and-play unit from a manufacturer we represent, and it’s on the shelf. For the shop that needs to do something this week, it’s the move.

If you’re running production welding: MicroAir TM1000

This is the one that fits most Southwest fab shops. Self-cleaning cartridges, dual-arm option, real production duty. Built to run every day for ten years.

• 1,000 CFM through dual self-cleaning cartridges — no disposable filter to throw away every few months
• Roto-Pulse® cartridge cleaning — push a button and the system pulses your filters clean. Auto-Pulse option puts it on a timer so nobody has to remember.
• Dual-arm option — run two welding stations from one cabinet. Solves the “I’ve got two welders going at once” problem with one unit instead of two.
• 120V standard at 14.4 amps. Three-phase 208V/230V and 460V motor options if you’ve got that power.
• Arm options — 6″ or 8″ at 7′ or 9′ reach; dual 4″ arms for tight stations; backdraft hood and downdraft table attachments available
• Optional 99.97% HEPA afterfilter for stainless and chrome work
• 72 to 76 dB at six feet depending on filter setup — quieter than your shop compressor
• Needs 80 PSI shop air for the cleaning cycle (every fab shop already has this)

MicroAir doesn’t allow public pricing on the TM1000, so we don’t post it. Configured with the arm and filter spec for your shop, you’re around $10,000 delivered, give or take depending on options. We carry bigger units too if your shop runs heavier than the TM1000 covers.

Lead time on MicroAir runs around six weeks. Worth the wait if what you’re putting in is going to run every day for the next decade.

If it’s a smaller shop or lighter welding: MicroAir TM500

Same MicroAir build, scaled down. Right call if you’ve got one main welding station, lighter or intermittent welding, or a tight space.

• 400 to 700 CFM at the hood, depending on attachment
• Built-in spark trap and baffle — sparks stop before they hit the filter
• Disposable HEPA filter — 95% MERV 16 standard, or 99.97% MERV 17 for stainless and chrome
• 14-gauge welded steel — same construction grade as the TM1000
• 120V plug and play. 16″ × 16″ footprint, 39″ tall folded
• 70 to 76 dB at six feet depending on filter — quieter end is with the HEPA

TM500 pricing also runs dealer-only. Delivered to a Southwest shop with the arm you need, you’re in the $5,000 to $5,500 range depending on attachments. About six weeks out, like the TM1000.

If your shop has tight welding bays and you’re weighing the TM500 against other small-footprint options, our compact welding fume extractor comparison walks through how the ELEVENT, MicroAir, and Fume Dog stack up at the weld.

If you want help working out what CFM and arm length actually fit the welding you do, our welding fume arm sizing guide walks through it.

Heavier than that?

We carry bigger MicroAir units for round-the-clock production, baghouse setups, and dedicated downdraft tables for plasma and grinding. If your shop runs heavier than the three above, call us — we’ll size and quote the right machine for the job instead of selling you what we have on hand.

When a portable isn’t enough

We don’t sell systems to shops that don’t need them. Here’s the honest truth on when a portable — even the TM1000 — stops being the right answer:

• Four or more welding stations running at the same time. A TM1000 handles two stations with the dual-arm option. Past that, you’re better off with one central cartridge collector and source-capture arms at each booth. Here’s the math on source capture vs. central.
• You’re cutting plasma. Plasma fume is hotter and finer than a portable arm pulls right. A downdraft table or a dedicated plasma collector is the answer there.
• You’re grinding combustible metals — aluminum, magnesium, titanium. That’s not a fume extractor question. That’s a wet collector and explosion-protection conversation, and the rules are different.
• You’re trying to bid for Honeywell, Raytheon, Boeing, or one of the defense primes here in Arizona. Those guys want to see system specs on your shop drawings before they’ll talk award. A portable doesn’t carry the paperwork an engineered system does.

When you hit any of those, the conversation shifts to an engineered system — typically $125,000 to $225,000 depending on size, dust load, and how your facility’s built. Our 2026 dust collection system cost guide lays out exactly what that gets you, by collector type and facility size. No “call for a quote” runaround.

A word on OSHA — short version

You knew this was coming. We’ll keep it short.

California enforces hard. Cal/OSHA shows up. They write tickets. Arizona, Utah, Nevada — not really, not yet. We know the shops in this region. Most have been running open-door for decades and nobody from the state has ever set foot inside. We’re not going to pretend that’s about to change tomorrow.

Two things to keep in your back pocket anyway.

One — guys moving here from California, from union shops up north, from primes like Boeing already know what normal looks like. The air in your shop isn’t only an OSHA question. It’s a hiring question.

Two — the second you try to bid Honeywell, Raytheon, Boeing, or one of the defense primes, they ask about your air. Most Southwest shops never get to bid that work because they can’t answer the question. A portable doesn’t fix that on its own, but it’s the first step toward being a shop that can answer when it gets asked.

If you’re getting ready for an inspection or a prime audit, our NFPA 660 compliance checklist walks through what gets looked at.

Every engineered system we install in the Southwest is built to NFPA 660 — the unified combustible dust standard effective January 1, 2026 — and it passes inspection or we fix it at no charge. Pass-or-free. That’s our standard whether your AHJ checks for it or not.

If you run a welding supply counter

This article’s built so you can hand it across the counter. When a customer walks in asking about smoke in his shop, you don’t have to walk him through the whole sizing conversation yourself — point him here.

If he wants the Elevent off the shelf, that ships from us in days and the price is right on the page. If he wants the TM500, TM1000, or anything bigger, send him our way — we’ll size it, quote it, and we’re happy to talk through how the deal works for your counter on the back end.

For more on how we work with welding and metal fabrication shops across the Southwest, that page has the rest.

Frequently asked questions

Will a single portable handle a flux-core station?
Yes, if it’s sized right. Flux-core throws more smoke than MIG or TIG, so go to the higher end — 6-inch hose or arm at 600 to 1,000 CFM. The TM1000 was built for this. The TM500 with a 4-inch arm at 400 to 450 CFM works for MIG and TIG but is undersized for heavy flux-core.

How loud is it? Can my crew talk over it?
The TM500 runs 70 to 76 dB at six feet depending on filter spec — the quieter end is with the HEPA. The TM1000 runs 72 to 76 dB. Both are quieter than your shop compressor. Normal conversation, normal radio, no extra hearing protection just for the extractor.

Do I need 220V or special wiring?
For the Elevent, TM500, and base TM1000 — no. All three run on standard 120V single-phase. The TM1000 has three-phase 208V/230V and 460V motor options if you’ve got that power and want it, but it’s not required.

Does the TM1000 need a special air supply?
The cartridge cleaning runs on 80 PSI shop air. Nearly every fab shop already has compressed air at 80 to 125 PSI standard — so this is rarely an issue. If you don’t have shop air, it’s not a dealbreaker, we’ll spec around it.

How much floor space?
The TM500 cabinet is 16″ × 16″ — same footprint as a roll-around tool box. The TM1000 is bigger, roughly 24″ × 35″ with the cabinet, plus the arm reach. Both fit between welding stations without taking the floor over.

What about plasma cutting?
A portable can handle the occasional plasma cut but it’s not the right answer for a dedicated plasma station. Plasma fume is hotter and finer. For plasma, look at a downdraft table or a dedicated plasma collector instead.

How often do I change the filter and what does that cost?
Depends on the unit. The TM1000’s cartridges are self-cleaning — you pulse them clean instead of throwing them out. The cartridges last years, not months. The TM500 and Elevent use disposable HEPA filters: single-shift MIG runs 6 to 12 months on one; heavy flux-core or stainless cuts that to 3 to 6 months. Replacement HEPAs run $200 to $400. The TM1000 saves you that line item entirely.

What if I have two welders going at once on separate stations?
That’s exactly what the TM1000 dual-arm option covers — two welding stations from one cabinet. The TM500 or Elevent only run one arm, so two of those means two cabinets. Past three or four stations going simultaneously, source capture from a central collector beats stacking portables.
