Welding machine welding nut is not firm, how to adjust the parameters? The nut has changed color, but it still falls off easily.
Spot welding nut first of all, if that kind of welding nut, in fact, you choose the power of the welding machine also have certain relations, secondly, look at the welding machine parameter settings
Two reasons. Welding parameter adjustment is unreasonable. The parameters of preheating time, pressure time, welding time, holding time and tempering time should be reasonable. Two, if the above parameters are not the main reason, it is recommended to buy a higher power resistance welding machine.
This is the wrong parameter adjustment. The machine you use should be an AC welder. Your soldering time is too long and the welding current is not enough. Your adjustment should be to shorten the welding time and increase the current. Because you have serious discoloration of the nut (welding discharge time is long), easy to fall off (welding current is small, spot welder welding your iron parts, rely on welding current. Except for brazing).Do you have any contact with me?. Contact information, I send you information. Or you see my information.
