tighten it clockwise. Connect one end of the positive output cable to the positive quick coupling, and the other end to the electrode holder. Connect the positive quick coupling to the positive pole of the output end and tighten it clockwise. (2) Argon arc welding connection method Connect one end of the positive output cable to the positive quick coupling, and the other end to the job. - Page 9 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.

Page 14: General Maintenance
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. -
