Section 4.
Initial Setup
Unpacking
The B22 Extended Power Pack is shipped with the batteries fully charged and is ready to use with no
additional setup required. If this Extended Power Pack was shipped to you, we recommend saving the
box and shipping materials in the event that any warranty service or other repairs are required.
Section 5.
Operation
Setup Instructions
*NOTE: This Power Pack is always on and does not require operation of a power switch.
STEP 1: Start with the Welder Power Switch in the OFF/EXTERNAL BATTERY position.
STEP 2: Connect the included Bridge Cable to the Welder and the Power Pack.
STEP 3: Follow startup instructions for the Welder.
*NOTE: With the Welder Power Switch in the OFF/EXTERNAL BATTERY position, the welder will be
powered from the Extended Power Pack ONLY. If all batteries are fully charged, with the Welder Power
Switch in the INTERNAL BATTERY WELD position, the welder will be powered from the Welder AND
Extended Power Pack together which can double the weld time and improve weld quality.
Section 6.
Routine Maintenance
Inspecting for Damage or Wear
Before each use, inspect the Power Pack for damage or excessive wear. DO NOT turn on or use the
Power Pack if there are any exposed or broken wires or any missing components or parts. DO NOT turn
on or use the Power Pack if it is wet or there are any signs of moisture inside of the case.
Maintenance
To extend the life of the Power Pack, vacuum out any dirt or dust and wipe down surfaces with a dry
cloth. Recharge the batteries after any use and keep the batteries fully charged as much as possible.
Battery Replacement
With proper use and charging, the batteries should last several years. Batteries can be replaced by the
user, by Badger Welder, LLC, or by one of our service centers. Please contact Badger Welder LLC for
battery replacement instructions or a list of service centers. To avoid damage to Power Pack and
possible personal injury, do not attempt to open the case without instructions. Opening the case
without instructions from Badger Welder, LLC will void the warranty.
