If having rings, the machine can be transited using rings. While HUAYUAN Welding Machine Manufacture reminds users, there is possible risk to damage the welding machine. It is better to push the welding machine moving in use of its rollers unless special situations.
1 Summary Model description □□□ IGBT IGBT Inverter Rated Cutting Current Air Plasma Cutting Plasma Cutting Characteristics LGK-IGBT inverter air plasma cutting machine is the latest development cutter in our company. It has good characteristics as following: This cutting machine adopts IGBT inverter technology which has high reliability and efficiency. It is light weight. Stepless adjustable cutting current, suitable for cutting various thickness workpiece.
Cutting power should be 30cm away from the wall or other sealed-in objects. The distance between two sets should be above 30cm. The operation height should be less than 1000m. 4 Technical Parameters Main technical parameters Model LGK-63MA LGK-100MA Parameters Input Voltage 3~380/415V 50/60 Hz Rated Input Capacity 9.3KVA 15.8KVA...

Cutting ground wire outlet: To connect cutting ground wire; Torch control outlet: to connect the torch control signal wire Air & Power output terminal: the current output terminal is also the compressed air output terminal. It is gas pipe connector to connect water-cooled torch when the water-cooled torch is used, and it is connector to connect torch air-cooled cable when air-cooled torch is used.
Installation of power wire Shut off the power switch first. Connect the power input wire of cutter back panel to distribution box which meets the parameters in the diagram above. The green-yellow wire is protection ground wire, which must be connected to earth reliably. Earth connecting method should follow state standard.
Operation strictly accordant with the following steps Notes: Electric shock Cutting may cause fire or explosion Splashes may ignite flammable materials nearby. hurt or even kill man. Notice Those materials should be 10m away from the Shut working place. power during connection Do not touch the conducted parts...
The water in reducing valve and air compressor should be drained out frequently. The cutting speed should not be too fast, so that it can avoid molten slag and arc reflection caused by incomplete cutting, but the cutting speed should not be too slow too, it will have workpiece red-hot and affect cutting quality.
Eliminate the cutting burr The characteristics of the incision burr The ordinary cutting surface is smooth and clean, but if the parameter selection is not suitable, and electrode centering is not good, then burr may be formed on the cutting surface. Slag is formed by molten metal and its oxide which is adhesive to the bottom edge of incision and solidified.
incision, square upper side and no metal slag seam on the lower side is obtained. 10 Troubleshooting & repair If there is trouble caused by high voltage in the machine, a professional electrician or serviceman of our company is required to repair it.
