Analyzing the Impact of Spot Welding Distance in Medium Frequency Spot Welding Machines

In continuous spot welding with a medium frequency spot welding machine, the smaller the spot distance and the thicker the plate, the greater the shunting effect. If the welded material is a highly conductive lightweight alloy, the shunting effect is even more severe. The minimum specified spot d... Read More

What is the pre-pressing time of the intermediate frequency spot welding machine?

The pre-pressing time of the intermediate frequency spot welding machine generally refers to the time from the start of the equipment’s power switch to the action of the cylinder (movement of the electrode head) until the pressing time. In single-point welding, the total time of pre-pressi... Read More
