DC WELDING INvERTER FOR MANUAL ARC WELDING SAFETY WARNING On the process of welding or cutting, there will be possibility of injury, so please take protection into consideration during operation. For more details please review the Operator Safety Guide, which complies with the preventive requirements of the manufacturer.
1.1 EqUIPMENT • Repair and maintenance to be performed by authorized personnel only. • The welding machine is to be maintained in good operational conditions (dry and clean). • The welding machine is not to be positioned in a closed space or next to a wall while welding in order to avoid problems with venting.
2.0 GENERAL INFORMATION 2.1 DESCRIPTION 1. Digital current display 2. Welding current adjustment 3. Digital voltage display / wire speed 4. Dial for adjusting voltage/down slope/arc force 5. POWER ON indication light - is on when the welding machine is connected to a live socket and is on.
3.0 INSTALLATION 3.1 MAIN CONNECTIONS Before connecting to the power grid, verify the supply voltage is in range of the machine parameters. • The power cable plug is to be connected to standard approved socket, with the proper protections. • The ground line (green & yellow) is to be connected to the grounding pin. 3.2 MIG WELDING OPERATION 3.2.1 MOUNTING THE WIRE SPOOL The machine is designed to use 11lb spools (8"...
3.2.2 SETUP FOR MIG-GUN MIG (GMAW) WELDING WITH GAS SHIELDED MIG WIRE A. Select MIG mode with the process selection control (11). B. In most cases the MIG polarity selector (22) is to be connected to the negative position (-), as shown in the sketch.
3.2.4 SETUP FOR WELDING WITH SELF SHIELDED MIG WIRE A. Follow the above steps according to the type of welding gun used (3.2.1 or 3.2.2), with the following differences is steps B and E: B. In most cases the MIG polarity selector (22) is to be connected to the negative "-", and earth cable connects to "+"...
current (5A) t2~t3: During the whole welding process, the gun switch is pressed and held without releasing; t3: Release the gun switch, the output current slopes down; t3~t4: The output current slopes down to minimum current (5A), stop arc; adjustment range of down slope time: 0~5S;...
