Have you considered the following problems with electric welding machines that have been in use for a long time:
- The machine's power is insufficient to weld thicker sheets;
- The machine is too large for common welding tasks;
- The machine is very heavy and you need a lighter option.
Don't wait until you buy an electric welding machine to realize it's not the right option for your needs.
6. Energy consumption and economic benefits of electric welding machine
As a product vigorously promoted by the country for its energy-saving ability, how much energy can an inverter welding machine save for us?
The actual measured input current for a two-phase AC welding machine ranges from 33A to 35A, as determined through a comparison of welding with a 3.2 electrode and 130A current.
The actual measured input current for a three-phase DC welding machine is 6A.
Energy consumption is calculated as follows:
AC welding machine power consumption:
P=LJI=380*33=13.3KW
Inverter welding machine power consumption:
P = 1.732 * IU = 1.732 * 380 * 6 = 3.95 kW
So, based on 26 days per month, 8 hours per day and 80% utilization rate:
（13.3-3.95）*8*0.8*26＝1361.36（kwh）
Using a DC inverter welding machine to weld 3.2 electrodes can result in savings of 1,361.36 kilowatt-hours per month compared to an AC welding machine.
Similarly, when compared to welding with 4.2 electrode and 175A current, each inverter DC welding machine can save 2,204.8 kilowatt-hours per month.
7. Other precautions
When purchasing a welding machine, it is important to check the nameplate for information such as the manufacturer's name, production address, specifications, welding current adjustment range, charging duration, machine weight and other relevant details, and choose a product that meets your specificities. it needs.
Since electric welding machines are subject to national mandatory certification, ask the seller whether the product has passed 3C mandatory certification and check this information online.
It is recommended to prioritize dealers with a strong reputation for providing guaranteed after-sales service.
