The properly used welding machine grants a high degree of operational security but can, in case of improper handling, lead to property and personal damage. -
Page 5: Operator Protection
Regulations for the prevention of accidents Operator protection All people must be protected during the welding process, with appropriate measures against UV radiation, noise, heat and gas pollutants emitted during welding. Never expose yourself to the influences of arc and the hot metal slag without a protective mask and appropriate protection. Welding work without consideration of these standards could cause serious health problems. -

Prior to beginning, the operator has to assure that close at hand there is both the welding power source (example: DTX-2200 AC/DC) and the cooling device (example: HR 22) and that both are working at the same feed voltage (see the two data panels positioned under the respective bases). -
Page 12: Start-Up / Drainage
Start-up / drainage 10 Start-up / drainage Before connecting the unit to the welding power source, check the rating plate and make sure the voltage and frequency of the main power correspond. Check that the main circuit breaker on the equipment is turned to “O”. Upon the first usage following a period of extended inactivity of the cooling unit or in the case in which the electro pump does not go under pressure (slight whistle), it is necessary to undertake drainage in order to eliminate all the air bubbles present within the hydraulic circuit. -
