Our welding machine and grounding wire did not bother it at all.? It's still the same, but the welder is a little bit out of arc Partial arc? What's the matter?
Compared with the human body, the earth resistance is small, when the equipment (electrical equipment) leakage lead to the shell charged, the current flows directly into the small resistance of the earth, to avoid electric shock. Therefore, the grounding of the electrical appliance is required
The ground wire of an argon arc welding machine is an important tool to ensure the safety of the staff in case of accidental voltage on the equipment and lines that have been cut off. According to the regulations, the grounding wire must be made of bare copper flexible wire above 25mm 2.
Avoid electric shock. You should use a DC welder for bias arc. Because of the magnetic field, will certainly affect the molten iron and arc. No arc, please check the cleanliness of the workpiece. It is estimated that you are using a high pressure arc, it is possible that the tungsten level is too far away from the workpiece. It is possible that the arc striking part of the welding machine is not adjusted properly and that the adjustment is far away, but not too far so that it does not discharge
