About coolant
（1）
ensure to use antifreeze as coolant
Please use ethylene glycol antifreeze (other salts and alcohol antifreeze may corrode metal parts such as
welding gun and water pump).
NOTE: When using the coolant, please use the same brand of antifreeze from the same manufacturer. It is
forbidden to mix the antifreeze from different manufacturers.
Please buy antifreeze according to the local minimum temperature. The freezing point of antifreeze should
be lower than the minimum temperature of the environment.
（2）
In order to avoid the formation of coolant scale in the bucket, please change the coolant regularly.
Antifreeze once a year.
（3）
When not in use for a long time, be sure to remove the coolant from the coolant tank and coolant pipe
Some components in the coolant will precipitate in the coolant pipe, which will cause the water pump not to
operate normally Method of removing cooling liquid.
The water inlet pipe joint of the welding torch is inserted into the coolant inlet of the liquid cooling system,
and the exhaust joint is inserted into the coolant outlet of the liquid cooling system.
Blow the compressed air from the exhaust joint to discharge the coolant from the outlet pipe joint of the
welding gun.
