I want to buy a small inverter welder, I heard that welding machine is very light, how heavy is it? It's the kind of carry. And how much is the price?. I wonder if the welder can use an acid welding rod? When welding, is it the same as the feeling of communication? I used the DC blow, it seems a little big. It's not good at all.. There is also a big point of 315 inverter welding machine, how much is it?.
Inverter welding machine can use acid welding rod, acid electrode: slag with acid oxide based electrode."Inversion" and "rectification" are two opposite concepts. Rectification is the process of converting alternating current into direct current, while inverter is the process of changing direct current into alternating current. The arc welding power source adopting inverter technology is called "inverter welding machine"".The working process of inverter welding and cutting equipment, is a three-phase or single-phase 50Hz AC rectifier, filter get a smoother DC inverter circuit composed of IGBT or fet the DC 15 ~ 100kHz AC, the main frequency step-down transformer, rectifier and filter to obtain stable DC output again the welding current (or again the required frequency of the inverter output AC). The control circuit of inverter welding and cutting equipment is given by the circuit and driver circuit etc., by processing the signals of voltage and current feedback loop control, realize the control technology, using pulse width modulation PWM as the core, constant current characteristic and excellent welding process effect to obtain rapid pulse width modulation.
I know an iron power welder. The 4750 yuan I bought last month is an inverter welder. Argon arc welding. Acid and alkaline welding rod can be. Now, all pipes in Shanghai are made of this kind of welding machine. It weighs about 20 kilograms. It's very convenient to use
The kind of welding machine that you said could be used with an acid electrode. He has many functions, which can be shared by AC and DC, with separate DC or AC, of course, the price is different. About 20KG or so, the market is now available from 300-800. Import, brand, public can not be the same, the price varies greatly. The big 315 is now 450-550 between.
