Which is the lowest production cost, the ordinary welding machine or two welding machines?

The cost of DC welding machine is very low, depending on what you weld. After secondary welding, there is no welding slag, which is beautiful in appearance and generally does not need polishing.

Covered electrode for electric welding machine is very cheap, and it doesn't need shielding gas, but there is welding slag to be removed after welding.

There are many grades of welding machines to choose from, and the welding machine itself is cheaper than two welding machines.

You have to see how much filler metal is left in the weld after welding, and the same amount of filler can compare the price.

1. The coating outside covered electrode, and finally welding slag and shielding gas, do not belong to the filler metal.

2, every covered electrode has a covered electrode head, at least 5 cm, must be thrown away, does not belong to the filler metal.

3. covered electrode splashes heavily, and the splattered metal does not belong to the filler metal.

Besides other expenses, covered electrode also needs an oven, a heat preservation barrel, electricity for heating and waste covered electrode head for drying.

Also have to talk about welding power consumption, the same welding effect, the heat input of secondary welding is small, that is, the power consumption is less, and the inverter welding machine saves more electricity.

Let's talk about efficiency and speed first.

1, no need to bake covered electrode, saving time and effort.

2. covered electrode does not need to be replaced, so it is not necessary to start the arc again, saving time.

3, don't knock welding slag, at least reduce a coolie.

4. As far as welding speed is concerned, secondary welding is three times that of covered electrode. (just this one, one welder can top three, you calculate, how much money is saved by labor! )

The second welding machine is also a DC welding machine, which has stable current and gas protection during welding, and the welding quality is definitely better than that without protection.

The second welding machine has many advantages, such as saving time and effort.
