b) Ventilation Adequate ventilation is recommended at the place of installation. For example the following guideline should be followed: a) In case of the area being more than 300 square meters (per unit), no ventilation is required, provided the room is not completely airtight. b) In case of the area being less than 300 square meters and the welding is continuously performed, adequate ventilation is recommended with the help of vent fan or exhaust duct.
WELDING OPERATIONS Front Panel Select the parameters to be adjusted by adjusting the LEFT or RIGHT shift keys on the front panel, and preset the parameters to be welded through the panel ADJUSTMENT knob. Each welding parameter on the front panel can be independently adjusted, and the ranges are as follows: Pre flow Gas Initial current...
General maintenance No additional maintenance for fan is required as all parts of the fan are sealed. If the welding machine is used where there is a lot of dust, the dust may block the air duct of the welding machine and cause the welding machine to heat up. Therefore, it is necessary to use dry compressed air to remove the dust inside the welding machine at set intervals.
