Miller Bobcat 200 Air Pak Diesel (907760) — Weld, Power, 30 CFM Air

Miller Bobcat 200 Air Pak Diesel Welder Generator (907760) — Weld, Power and Air in One Machine

The Miller Bobcat 200 Air Pak is what you buy when you are tired of hauling a welder, a generator, an air compressor and a jump pack on the same service truck. All four live in one 618 lb diesel unit.

It puts out 210 amps of DC stick welding, 6,500 continuous watts of generator power, 30 CFM of rotary-screw air, and up to 300 amps of crank assist for dead jobsite equipment.

Price: $14,160.00 — in stock, free shipping.

Why Work-Truck Operators Choose It

The whole point of the Bobcat 200 Air Pak is consolidation. Miller built this unit to be up to 600 lbs lighter than competing air pak machines, which is bed space and payload you get back for tools, rod and parts.

Auto-Speed technology matches engine RPM to what you are actually asking of the machine. Light weld, low speed. Heavy draw, full speed. That means less fuel burned per day, longer service intervals and a quieter truck — 66 dB at idle, 73 dB at high speed.

Underneath is a 19 HP Kubota D722 diesel with a 60-amp alternator, electronic governor, 7-gallon fuel tank and a standard engine block heater for cold starts.

For best results, spec your truck bed layout before delivery. At 28.9 in. H x 20 in. W x 47.25 in. D (30 in. with exhaust), it fits most standard service bodies, but check clearance above the exhaust.

The Air Compressor Is the Real Selling Point

Most welder generators bolt on a reciprocating compressor that runs out of air and makes you wait. The Miller Bobcat 200 Air Pak uses a rotary-screw compressor with an electric clutch, delivering air on demand with no recovery pause.

You get 20 CFM at idle and 30 CFM at full speed, working pressure of 80–175 PSI, and 100% duty cycle. That runs virtually any air tool on a service truck, including most 3/4 in. impact wrenches. If pressure ever hits 200 PSI, the unit shuts the compressor down automatically.

Welding, Power and Battery Charge

Stick output runs 30–210 amps DC, with a 100% duty cycle at 120A and 20% at 210A. That covers structural repair, pipe work, heavy equipment fabrication and general field welding.

The generator side delivers 6,500 continuous watts through four 120V receptacles and one 240V receptacle — grinders, lights, plasma, pumps, portable heaters.

Battery charge and crank assist produce up to 100 amps of DC to charge 12V and 24V batteries, with up to 300 amps of crank assist to fire equipment that has been sitting. That single feature saves the callout fee every time a machine will not turn over.

Bobcat 200 Air Pak vs the Rest of the Range

Choose the Bobcat 200 Air Pak if you need air on the truck and 210 amps is enough welding output. This is the sweet spot for mobile mechanics, mining and equipment service, agricultural repair and utility fleets.

Step up if you need more amperage or multi-process capability. Compare the Miller Big Blue 400 Pro Kubota, the Big Blue 400 Pro Mitsubishi, or the Big Blue 600 Pro Kubota. For the largest dual-operator air pak, look at the Big Blue 800 Duo Air Pak with ArcReach.

Step down if you do not need air. The Miller Trailblazer 325 EFI gives you more welding amperage than the Bobcat at roughly half the price, without a compressor.

Ordering the Miller Bobcat 200 Air Pak

Every unit ships new from US stock with full Miller warranty coverage. Not sure whether 30 CFM covers your air tools, or whether 210 amps is enough for the material you run? Send a quote request or run a compatibility check and we will spec it against your actual workload.

FREQUENTLY ASKED QUESTIONS

What does “Air Pak” mean on a Miller welder generator? It means the machine has a built-in air compressor. On the Bobcat 200 it is a rotary-screw unit, not a reciprocating one, so it supplies continuous air instead of cycling and recovering.

Will 30 CFM run a 3/4 inch impact wrench? Yes, most 3/4 in. impacts fall inside the 30 CFM at 80–175 PSI envelope. Very large 1 in. impacts and high-consumption tools like sandblasters will outrun it.

How much can it weld? 30 to 210 amps of DC stick. At 120 amps you can run all day at 100% duty cycle. At the full 210 amps you get 20% duty cycle, which is two minutes of arc time in every ten.

Can it MIG or TIG weld? Stick is the native process. MIG requires a separate wire feeder and TIG requires a Miller HF unit, both sold separately. If multi-process out of the box matters, look at the Big Blue Pro range instead.

What engine does the Bobcat 200 Air Pak use? A 19 HP Kubota D722 three-cylinder diesel with a 60-amp alternator and electronic governor. Parts and service are widely available, which is a large part of why fleets buy it.

How long does it run on a tank? The 7-gallon tank plus Auto-Speed engine management gives a normal service-truck workday between fills for most operators. Actual burn depends on weld load, air demand and idle time.

What is crank assist and why does it matter? It delivers up to 300 amps of DC to turn over equipment with a dead battery. For a mobile mechanic that eliminates carrying a separate jump pack and often turns a two-trip callout into one.

Does it charge 24-volt systems? Yes — up to 100 amps of DC charging on both 12V and 24V systems.

Is it quiet enough for residential or hospital work? At 66 dB idle it is on the quiet end for a diesel engine drive, but confirm against local site noise limits before scheduling night work.

Do you ship internationally? Yes. See shipping information, and warranty information for coverage terms.
