Mobile Weld Station
Portable Welding Booth with Fume Extraction and UV Flash Protection — Works Where the Work Is
What Is the Mobile Weld Station?
The Mobile Weld Station is a portable welding fume extraction and filtration system designed to capture and remove particulates and VOCs generated by the welding process. Its patented non-venting recirculation design utilizes a custom combination of high-efficiency particulate filters along with activated carbon and potassium permanganate filters engineered specifically for welding fumes.
When used with its attached curtain enclosure system, the Mobile Weld Station becomes a complete portable welding booth — combining fume extraction, filtration, and weld curtain enclosure in one mobile unit. The top curtain is constructed of 20 MIL clear flame-resistant PVC, and the side curtains are 14 MIL flame-resistant vinyl UV-protective welding curtain material that is oil, water, mildew, and spark resistant.

Product Overview
Weld Fume Extraction, Anywhere
The Mobile Weld Station is the most versatile and flexible welding booth on the market. Its patented non-venting recirculation design means you eliminate the need for costly ventilation modifications or air make-up systems. By using cleaned, recirculated air, you reduce energy costs by utilizing your shop’s existing heated or cooled air, while removing welding fumes at the source.
The unit provides a mobile solution to weld fume extraction, allowing you to bring filtration to the work rather than transporting parts to a fixed ventilated area. This increases productivity and adds flexibility to your welding operations.
Complete Portable Welding Booth
When used with its attached curtain enclosure system, the Mobile Weld Station becomes a complete portable welding booth — fume extraction, filtration, and UV-protective weld curtain enclosure in one mobile unit. The top curtain is 20 MIL clear flame-resistant PVC for visibility. Side curtains are 14 MIL flame-resistant vinyl UV-protective welding curtain material that is oil, water, mildew, and spark resistant.
Welding-Optimized Filtration
The Mobile Weld Station uses a custom combination of filters designed specifically for welding fumes: high-efficiency extended surface filters for particulate capture, granular activated carbon and potassium permanganate filters for VOC and fume compound removal, and aluminum mesh spark arrestor filters for spark containment. This specialized filtration system effectively captures and removes the harmful compounds specific to welding fumes.

Motor Horsepower Options
Two motor options are available to match your welding application needs. The 3/4 HP motor (49 Series) delivers 2,900 CFM and features a standard 15-amp* plug. The 1-1/2 HP motor (54 Series) delivers 3,900 CFM for higher-volume applications and is provided with a 20-amp* plug. Both motors are sealed, maintenance-free, and UL Listed for hazardous locations.
All motors feature direct-drive fan assemblies — no belts to replace or maintain. Backward-curved aluminum fan wheels provide non-sparking operation and are statically and dynamically balanced for quiet, efficient performance.
*Commonly set up for 115V power; can be set up for 230V single phase power if desired. Alternative power options can be accommodated.
System CFM (Cubic Feet per Minute)
CFM measures the volume of air the unit moves through its filter system per minute. Higher CFM means faster air exchange and accelerated capture of welding fumes and particulates.
- 49 Series (3/4 HP): 2,900 CFM — suitable for lighter welding work and TIG applications
- 54 Series (1-1/2 HP): 3,900 CFM — recommended for heavier welding, stick welding, and higher-volume fume extraction
CFM is measured through the unit’s welding-specific filter set. Actual airflow may vary with alternative filter configurations.
Weld Curtain Enclosure System
The optional attached curtain enclosure system converts the Mobile Weld Station into a complete portable welding booth — combining fume extraction, filtration, and UV-protective weld curtain enclosure in one mobile unit. The top curtain is constructed of 20 MIL clear flame-resistant PVC for visibility. Side curtains are 14 MIL flame-resistant vinyl UV-protective welding curtain material designed for grinding, sparking, and dust/splash/spray confinement.
The UV-protective enclosure curtain material is oil, water, and mildew resistant. Models 4900W and 5400W include the weld curtain enclosure. Base models (4950W, 5450W) are available without the enclosure for open-air fume extraction applications.

Frequently Asked Questions
The Mobile Weld Station is designed to extract and filter fumes from all common welding processes including MIG (GMAW), TIG (GTAW), stick (SMAW), and flux-cored (FCAW) welding. The welding-specific filter set includes spark arrestors, high-efficiency particulate filters, and activated carbon/potassium permanganate filters to handle the unique compounds found in welding fumes.
While all Shop-Pro equipment shares the same rugged construction and patented recirculation design, the Mobile Weld Station uses a completely different filter set engineered specifically for welding fumes. It includes aluminum mesh spark arrestor filters, high-efficiency extended surface filters, and activated carbon/potassium permanganate filters designed for the compounds specific to welding. The curtain enclosure also uses UV-protective curtain material for the side curtains rather than clear PVC.
No. Like all Shop-Pro equipment, the Mobile Weld Station uses a patented non-venting recirculation design. Air is drawn through the welding-specific filter set and recirculated back into your facility — no exhaust ductwork, no air make-up systems, and no building modifications required. This also means significant energy savings since conditioned (heated/cooled) air stays in your facility.
The Mobile Weld Station is commonly set up for 115V single-phase power. The 3/4 HP models (49 Series) feature a 15-amp plug, while the 1-1/2 HP models (54 Series) have a 20-amp plug. Each unit comes with a heavy-duty 30-foot power cord. Both systems can be set up for 230V single-phase power if desired. Alternative voltage configurations are available upon request.
The curtain enclosure system includes a top curtain constructed of 20 MIL clear flame-resistant PVC for visibility, and side curtains made from 14 MIL flame-resistant vinyl UV-protective welding curtain material. The side curtain material is specifically designed for grinding, sparking, and dust/splash/spray confinement in welding enclosures, and is oil, water, and mildew resistant. Models 4900W and 5400W include the complete curtain enclosure.
Four models are available across two motor sizes. The 49 Series (3/4 HP, 2,900 CFM) includes: Model 4950W (base filtration unit) and Model 4900W (with UV-protective curtain enclosure). The 54 Series (1-1/2 HP, 3,900 CFM) includes: Model 5450W (base filtration unit) and Model 5400W (with UV-protective curtain enclosure). Also available in our larger A-Series format.
While the Mobile Weld Station is optimized for welding fume extraction with its specialized filter set, the adjustable filter rack system allows for alternative filter combinations. If you need a more versatile unit that can also handle paint spraying, sanding, and other applications, consider the Mobile Work Station® or Mobile Prep Station, which offer broader filtration options while also being configurable for light welding work.
Filter maintenance is straightforward thanks to the quick release filter door system, adjustable filter rack system, and common sized 20″×20″ filters utilized. The included Magnehelic pressure gauge indicates when filters need replacement by measuring pressure drop across the filter bank. The welding filter set includes aluminum mesh spark arrestor filters which are washable and reusable. Replacement filters and filter sets are available directly from Shop-Pro Equipment through our Supplies page.
