Trailblazer® 302 Air Pak™ - GASOLINE
•Powerful all-in-one tool designed for repair and construction with multiprocess weld quality, generator power, air compressor and
battery charge/jump start •Superior arc performance. Preset dig settings optimized for the majority of Stick welding applications, bestin-class Wire arc performance, and two Lift-Arc™ TIG modes for most DC TIG applications •Strongest combined generator/compressor
power. Delivers an industry-leading 13,000 watts of peak generator power independent of weld settings — can power a Spectrum® 875
plasma cutter, and provide air for plasma cutting at the same time (rated 5/8” mild steel). •Rotary screw air compressor. Delivers up to
31 CFM and 160 PSI of air with no storage tank. Gives 100% deliverable air and runs many tools at idle speed. Air outputs are rated at
an industry-high 40°C (104°F). Front panel air pressure adjustment and automatic overpressure shutdown with indication. Designed
for more than 30,000 hours of operation and warranted for three years by Miller. •Battery charge/jump start. Provides selectable 12 or
24-volt battery charging capability with up to 450 amps of battery jump-starting capability. Convenient front panel battery charger/jump
starter access.

Big Blue® 350 PipePro - DIESEL
•Designed exclusively for transmission pipeline work, the Big Blue 350 PipePro offers stick as well as MIG/flux-cored welding capabilities to meet highstrength steel requirements and is ideal for the most demanding pipeline jobs •Improve productivity and quality with advanced RMD® and pulsed MIG
processes with the FieldPro Smart Feeder •Auto Remote Sense™ (ARS) detects if a remote control is plugged into the 14-pin receptacle and eliminates
confusion of a remote/panel switch •Low OCV stick (VRD) reduces the open-circuit voltage to 15 volts when the welding power source is not in use,
increasing operator safety without compromising arc starts •Heavy-duty low-speed industrial engines are designed to operate over 10,000 hours before
the first basic overhaul. Backed by worldwide support and service. •Infinite arc control allows the arc characteristics to be changed for specific applications
in stick and MIG •LINE-X® cover is workbench tough and provides superior impact, corrosion and abrasion protection •Engine coolant temperature gauge
and meter maintenance displays: Fuel gauge, Hour meter function, Oil change interval, High coolant temperature and low oil pressure shutdowns, and
Low fuel shutdown - engine shuts down before system runs out of fuel, making restarts easy •Standard features include digital preset weld meters, output
contactor control, automatic idle and 120-volt block heater.
SF model additional features: •Simple-to-set controls have integrated support for Smart Feeder, simply turn the knob to either MIG VS or FCAW VS for
optimal performance •Stainless steel appearance package provides additional exterior protection to withstand corrosive environments
Processes: •Stick (SMAW) •MIG (GMAW) •Flux-cored (FCAW) •RMD® (Available only on Big Blue 350 PipePro SF models) •Pulsed MIG (GMAW-P)
