ANDELI TIG Series Instruction Manual page 27

 It is forbidden to use the welding machine for thawing pipes。
 The back of each welding machine is attached with a ground screw, and marked with a
ground mark. Before use, select a cable with a section greater than 2.5mm2 and ground the
welding machine shell reliably to release static electricity or prevent accidents that may
occur due to electricity leakage.
 If the welding machine exceeds the standard load duration, the welding machine may
suddenly enter the protection state and stop working, which means that the welding machine
exceeds the standard load duration. If the temperature is too high, the temperature control
switch will be triggered and the welding machine will stop working. Meanwhile, the yellow
indicator light on the front panel will be on. In this case, you do not need to unplug the
power supply so that the cooling fan can continue working to cool the welder. When the
yellow indicator light is off, the temperature drops to the standard range and the welding can
be resumed.
2. Maintenance
Warning：
All maintenance, service and cleaning work must be performed with power removed.
！
Make sure you have unplugged the power cord before opening the casing.
 Dedust regularly. Use dry, clean compressed air to clean up the system. Dedust every day
when operating in smoky conditions or severely polluted air.
 The compressed air should be delivered at the required pressure to avoid the destruction of
the internal components.
 Check the internal contact areas to insure a tight connection (especially the plug-in joints or
components) and reinforce the loose contact. If any rusting or oxidation occurs, use
sandpaper to remove the oxide film and reconnect.
 Avoid water and moisture penetration. If this situation happens, apply a drying treatment to
the inside of the welder and then start a megger insulation test which should include the
insulation between connection joints as well as joints and casing. The welding operation
could be continued only if no error detected.
 If the welder is not used for a long period of time, seal it in the original packaging and store
