Checking requirements
Safety
All maintenance and checking should be carry out after the power
is completely cut off. Make sure the power plug of the machine is
pulled out before uncovering the welding machine.
When the machine is powered on, keep hands, hair and tools
away from the moving parts such as the fan to avoid personal
injury or machine damage.
Periodic check
Check periodically whether inner circuit connection is in good
condition (esp. plugs). Tighten the loose connection. If there is
oxidization, remove it with sandpaper and then reconnect.
Check periodically whether the insulating layer of all cables is in
good condition. If there is any dilapidation, rewrap it or replace it.
If not proper, tighten or
replace the components.
Use appropriate methods
according to the work site
situation to ensure safety
and normal welding.
