Quiet at only 71 dba (96 Lwa) at 23 ft at maximum output. Improves work site communication.

The VaultThe Vault-ultimate control board reliability. Hardened solid-state control technology, housed in a sealed vault. The vault's sealed connections are made through watertight plugs that make these components impenetrable to dust and moisture.

Meter maintenance displays:

  • Hour meter function
  • Hours to oil change indicator keeps track of maintenance needs to ensure peal performance.
  • High coolant temperature and low oil pressure shutdowns
  • Low fuel shutdown - engine shuts down before system runs out of fuel, making restarts easy.

Auto Remote Sense (ARS) detects if a remote control is plugged into the 14 pin and eliminates confusion of the remote/panel switch.

Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.

Optional Stainless Steel Appearance Package provides additional exterior protection to withstand corrosive environments.
