How to adjust current and voltage in carbon dioxide gas shielded welding

There are generally two types of gas shielded welding machines: integrated (without) split (with wire feeder).

The current is to adjust the welding wire speed, and the voltage is to adjust the welding wire splash. ? If the voltage and current don't match, the splash will be smaller if the voltage is larger, but it can't be too big. The voltage needs to be mastered by yourself. The voltage is slightly greater than the current, such as current 300? . ? Just adjust the voltage to 32, even if you are given a value, the values of the two welders are the same, and the welding effect is different.

Carbon dioxide gas shielded welding is a kind of welding method, which uses carbon dioxide gas as shielding gas for welding. Simple operation in application, suitable for automatic welding and full welding. Welding should be windless and suitable for indoor operation.

Current is to control the wire speed of welding wire, and voltage is to control the melting degree of welding wire. The method of overhead welding is to pull the welding wire directly to the included angle. If it is more than 8mm, stick a ceramic liner on the back and pull it directly. If the lid is going to swing up and down, then radian according to the width.

Turn on the control "power" switch on the front panel of the welder, and the indicator light will be on. Pass the welding wire through the wire feeding wheel, welding gun and contact nozzle, and check the operation of the welding wire. There should be no jam. Turn on the switch and pressure reducing valve of the preheater, turn on the "gas detection" switch, check and adjust the flow of protective gas, and then turn off the "gas detection" switch.
