The current is too small to the maximum, indicating more than 300 or not
Argon arc welding welding current adjusting welding current of TIG welding is usually chosen according to the space position of the workpiece material, thickness and joint, when the welding current is added, the penetration depth increases, the weld bead width and height increased slightly, but little increase, the welding current is too large or too small will cause the poor weld shape or welding defects, the position of the welding current to 80 ~ 110A is better, the ideal current value is 90A, when the spot welding current to 150 ~ 180A is better, the ideal current value is 160A.
Adjust the flow of argon argon flow is too small, weak and feeble protection gas, protection effect is not good, easy to produce and weld defects such as oxidation pores; if the gas flow is too large, prone to turbulence, the protection effect is not good, but also affect the stability of arc burning. The welding of position 1 does not require argon protection to the parts, only the gas flow of the welding gun is adjusted, and the flow rate of argon is adjusted to 7~10 l/min.
There are two problems. One is that the current potentiometer is out of order, and the other is your motherboard. If the line is not in good contact, the problem will occur
