Welding Machine Daily Inspection or Daily Check

Welding machine is an important power tool we are using in construction, manufacturing and maintenance sites.

The machine we are going to use in the site may newly purchased or it is transferred to this site from another site.(eg: May be from another project or manufacturing unit). Whether it is new or old irrespective of this we have to conduct daily inspection for the machine.

There are some important points we need to check on daily basis before using the welding machines.

1. Check the ON/OFF Switch

Check whether the switch is provided or not,Check is there any damage in the switch, whether it is working properly (It is connecting and disconnecting the power supply during operation,not bypassed),On off symbol on the switch is visible and correct with respect to the operation.

Check whether the power indicator LED working properly, no damages in it and it is clearly visible. 

3. Check welding cables are connected to the machine using lugs.

4. Check for any insulation damages in the welding cables.

5. Check for any insulation damages in the power cable.

6. Check the power cable plug top and connection to the machine.

7.Check the welding holder and it's spring action.
