Page 3: Brief Introduction
1 Brief Introduction ECL welder uses imported IGBT and fast recovery diodes as main electric components. It is supplemented by a specially developed main PCB board. In addition, the uniform regulation of welding current has been designed to guarantee the arc reach good welding process adaptability. -

Connect the quick plug with electrode holder to the positive terminal and then tightened them up clockwise. 4.4 Workpiece Connection Connect the quick plug with earth clamp to the negative terminal on the front panel below. And then tighten them up. Access the earth clamp to the workpiece. Warning! It is forbidden to connect the workpiece to the welder with iron or other poor conductors. -
Page 11: Procedure
NOTES: When the welder works for a long time, the high temperature indicator will light. This means the inside temperature has exceeded its standard. And you must turn off the power immediately for a period until it recovers. * You have to wear canvas overalls and face mask to prevent from arc light and heat radiation. -
Page 12: Maintenance
Warning! The welding slag should not be removed until it is cooled down. Don’t point it at the other people while knocking on the slag incase that it will do harm with pop-up slag. 5.4 Maintenance * The major difference between inverter arc welder and traditional welder is the inverter welder has lots of advanced electronic components. -
