There are no electric hog-ring tools made. However, the solution to job-site use where compressed air is not available is our C02 accessory kit. It uses common paint-gum type cartridges which can be re-filled at most sporting good shops for $1.50 or less. The kit comes with a convenient belt hanger hook and all fittings necessary to quickly adapt any pneumatic hog-ring gun to C02 from compressed air.
