For new or long-term unused welding machines, the insulation resistance between the windings and between the windings and the casing is often greatly reduced due to moisture. Short

First of all, let's look at the first problem of the electric hot melt welding machine. There is no power when connected to the power supply. Why is there no power? That is a probl

Connect the wires according to the operating requirements of the electrofusion welding machine, and set the correct welding parameters of the electrofusion welding machine. You can

1. Welding preparation Welding preparation is mainly to check whether the condition of the hot melt welding machine meets the operating requirements. For example, check whether the

The electric heating fusion sleeve is a special connecting pipe fitting that is compounded with a special electric heating network on a PE plate through secondary processing. It is

1. The electrofusion welding machine can perform fully automatic welding according to parameter settings. It has a user-friendly large-screen operation panel and a portable design.

1. The pipe openings to be welded have been cleaned up to standard according to the cleaning requirements. 2. When lifting steel pipes, special nylon slings for lifting pipes must

Not easy to arc 1. If the conductive nozzle is burned out, replace the conductive nozzle 2. If the selection of welding wire is inconsistent with the actual situation, select the a

1. Before work, clean the oil on the upper and lower electrodes. After powering on, there should be no leakage from the car body shell. 2. Before starting, turn on the control line
