Page 4: Safety
SAFETY Users of ESAB welding equipment have the ultimate responsibility for ensuring that anyone who works on or near the equipment observes all the relevant safety pre- cautions. Safety precautions must meet the requirements that apply to this type of welding equipment. - Page 5 WARNING ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR EMPLOYER'S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANU- FACTURER'S HAZARD DATA. ELECTRIC SHOCK - Can kill Install and earth the welding unit in accordance with applicable standards. Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
- Page 6 CAUTION! Class A equipment is not intended for use in residential locations where the electrical power is provided by the public low-voltage supply system. There may be potential difficulties in ensuring electromagnic compatibility of class A equipment in those locations, due to conducted as well as radiated disturbances.

Page 7: Introduction
INTRODUCTION General Connection in parallel can be done with all sizes of the LAF welding power source. The current outlet from each welding power source depends on its size, see below. The mains connection is to be done in the same way for Master and Slave. -

Page 12: Connection In Parallel Using Six-Thyristor Operation
Connection in Parallel Using Six-Thyristor Operation In this case the Master/Slave welding power sources are connected to the mains by way of six thyristors (three in each welding power source). This results in softer welding current as the phase shift is 60° instead of 120° . Connection of Master+Slave using the six-thyristor effect. - Page 13 IMPORTANT! Connect the right winding. Most power sources have more than one mains voltage. This applies particularly to machines designed for different mains voltages. Below you find examples how to connect master and slave to the mains when using power sources without multivoltage connections. - 13 - hga7d3ea...
