EnPak technologies and capabilities 

Auto-Speed™ technology – Automatically adjusts engine speed to match compressed air, battery charge and weld demands — reducing fuel consumption, maintenance costs and noise for a safer, more efficient jobsite.

Auto Start/Stop – Automatically turns the EnPak engine on and off based on demand, reducing fuel consumption and noise — which enhances safety and improves the work environment.

Battery charge – Up to 100 amps of DC power to charge 12/24V batteries.

CAN bus (SAE J1939) connectivity – Allows communication with a telematics system so customers can monitor engine data, machine loads and usage, which helps them to track service intervals, proactively schedule maintenance and improve diagnostics.

Chassis Power – Integrated into the truck battery system, Chassis Power monitors the battery and automatically charges it as needed.

Crank assist – DC power to jump-start vehicles that use 12/24V systems.

Power Priority – Enables operators to maximize available power by prioritizing the air compressor or hydraulic system based on what’s important for optimal tool performance. (Available on the EnPak A60 only.)

Rotary screw air compressor – Delivers high torque at lower speeds for optimal performance in every environment — even at high elevations. (Available on the EnPak A60 only.)

Turbocharged diesel engine – Uses two meshing rotors to compress air, rather than a reciprocating piston. Quickly delivers airflow, at 100% duty cycle and high reliability.

Industry terminology

cfm – Cubic feet per minute: A measure of air volume delivered by the air compressor.

Duty cycle – The percentage of available time that a machine or component can operate before cool down is required in a 10 minute period. A device with a 100% duty cycle can operate continuously with no cool-down time needed. 

GFCI – Ground fault circuit interrupter. Fast-acting circuit breaker designed to shut off receptacle power in the event of a ground fault.

gpm – Gallons per minute: A measure of fluid volume delivered by the hydraulic pump.

Open center hydraulic systems — Control valves are placed in series; one valve is operated at a time. Typical EnPak A60 application is a crane truck. (Our most common configuration for modern hydraulic systems.)

Closed center hydraulic system — Control valves are placed in parallel; all valves work independently. Used with multiple subsystems with closed center control valves. Typical EnPak A60 application is a lube truck.

Welding definitions

Arc controlAllows adjustment of weld arc from soft to stiff. Adjusts dig when process control is in stick mode and adjusts inductance when process control is in flux-cored or MIG modes. The amount of dig determines how much the amperage (heat) varies with stick arc length. Inductance determines the “wetness” of the weld puddle.  

MIG (Metal Inert Gas) – Coiled wire is fed through a gun; the wire is both the electrode and the filler metal. Shielding gas is needed unless self-shielded flux-cored wire is used. Fast and versatile.

StickUses flux-coated welding rods as the electrode and the filler metal; no shielding gas needed. Good for welding outdoors and with rusty/dirty material.

TIG (Tungsten Inert Gas) –Uses a non-consumable tungsten electrode and a separate filler metal rod. Argon shielding gas is needed. Precise; can produce aesthetically pleasing welds.
