Note: The phenomena listed here may be related to the accessories you use, gas, environmental factors and
power supply. Please try to improve the environment and avoid such situations.
Warning! Inexperienced or careless maintenance can lead to greater failure of
the machine, making formal inspection and maintenance more difficult. After
the welder is energized, there will be life-threatening voltage in the exposed
parts of the welder. Any direct or indirect contact will cause electric shock, and
serious electric shock can even be fatal.
8.3 Welding Procedure Checklist (for reference only.
The selection of welding current and arc voltage directly affects the stability, welding quality and
productivity of the welding process. To guarantee welding quality, it is required that the welding current and arc
voltage match each other well. They are usually selected according to the diameter of the used, the required
form of metal transfer and the requirements of productivity.
