The welding inverter has number of advantages before welding transformer. Process of work with the inverter more convenient, this device is capable to work also at low tension in network. Besides and the seam will turn out accurater and qualitative that is important.
Instruction
1. Attentively examine the welding machine and packing to it. There can be inscriptions: EN 60974-1 ""Arc welding equipment. Part 1: Welding power sources"" or GOST P IEC 60974-1-2004. It means that this welding inverter can work at temperature from-40 degrees to +40 degrees.
2. Do not buy the device if uses of the inverter given about temperature are not specified anywhere. Anyway it is undesirable to work with this device at subzero temperature. The climate of your place of residence can also influence the choice of the suitable welding inverter.
3. Pay attention to the admission of the device. 10-15% of admission will be suitable for more or less stable city power supply network, for country or rural networks it is necessary to buy the device with the admission of 20%. These inverters will work at voltage from 170B to 270B without any damages.
4. Choose the welding machine with the necessary electrode. At high tension you can take the inverter with 4-5 millimetric electrode in networks. If in the power supply network low tension (it is less, than 220B), it is worth buying the device with three-millimetric electrode, the bigger electrode will unstably cook.
5. Pay attention to that fact that the weight of standard welding inverters is approximately equal to 8-10 kg. Devices work with smaller weight shorter time. Look on ID (inclusion duration), 100% in this case will be equal to 10 minutes.
6. Do not take the device with low indicators. 20% of PV will mean that the device will work only two minutes, and eight minutes to be cooled and cool down. Look narrowly at the fan of the welding machine which was pleasant to you. Operation of the inverter depends on this part, fault of the fan can lead to breakage of all device.
7. Correctly look after the bought device. Regularly clean it from dust, remove the body and dust soft brush. You do not store the welding inverter in the cold room, low temperatures can damage it. At the correct and timely leaving your device will serve long time.
