1: Do not touch high-temperature parts such as the cutting tip and protective cover when cutting.

2: Turn off the power before replacing the torch parts

3: In order to ensure safety and cutting quality, please replace the new parts in time.

4: When replacing the cutting nozzle electrode, please install it firmly with special tools to avoid burning the cutting torch

Replace the electrode nozzle when the following conditions occur

1: The cutting slit becomes larger    2: the arc cannot be started      3: the cutting speed is sharply slowed    4: the nozzle hole is deformed    5: the cutting slope changes      6 electrode burning
