2.2 Cooling System
IMPORTANT!
To ease transportation, the i4s welder is DELIVERED WITHOUT COOLANT. Be sure to fill coolant
tank before turning on the welder. The cooling system turns on and off automatically. It starts at the first weld and
shuts off three minutes (or longer if needed) after the last weld IS completed. Make sure the water lines are connected
properly.
The coolant tank is located in the rear of the unit, inside the center column. It should be filled with a 50/50 water & an-
tifreeze solution. Be sure to turn off and disconnect the i4s from wall power before filling the coolant tank or changing
weld arms to prevent spillage. Maintain a level of at least 10L of 50/50 solution at all times and do not overfill. When
filling coolant it is recommended that a funnel be used to prevent unnecessary spills. When handling antifreeze or
50/50 solution, avoid contact of with skin, eyes, or mouth. See antifreeze directions for proper handling instructions.
The Coolant Level Indicator is
located in the lower left hand
side on the back of the i4s.
Be sure to check the coolant
levels regularly to maintain an
optimum of 10L minimum in the
tank.
Make sure the water cooling
hoses are securely clipped into
place before welding. Water will
leak if the water feed and return
hoses are not properly connected
(see cooling hose connections).
Always make sure the welding
arm is installed correctly, and the
arm handle is firmly secured.
The i4s is equipped with a closed
loop cooling system, 5-gallon
(20L) tank, radiator with high
powered fan cooling all the way
to the tip of the electrodes.
IMPORTANT!
Make sure the water cooling hoses are securely clipped into place
before welding.
IMPORTANT!
Turn off the power to the water pump before disconnecting water
hoses from the weld gun.
IMPORTANT!
The i4s welder comes without coolant to ease transportation, be sure
to fill coolant tank before turning on the welder.
