The Standard Coolant supplied with the Power Supply
can be used in ambient temperatures down to 10° F
(-12° C). If the ambient temperature will be below 10° F
(-12° C) then Super Coolant should be used. This coolant
can be used in areas where the ambient temperature drops
to -34° F (-36° C).
A typical system configuration will contain the follow-
ing:
• Power Supply with Running Gear and Handles
• Arc Starter Box
• Maximizer 300 Machine Torch with Mounting As-
sembly and Leads
• Torch Leads Extension
