Does the welder come with a TIG torch?

No, the TIG torch is sold separately.

What type of power supply does the welder require?

The welder requires a 230V (13A) power supply.

What safety features does the welder have?

Troubleshooting

Welder does not turn on.

Check the power supply and ensure the welder is properly connected to a 230V outlet. Check the power switch and the power cord for damage.

Poor weld quality or inconsistent arc.

Check the electrode diameter setting. Make sure the material is clean and free of rust or contaminants. Adjust the welding current using the infinitely variable dial.

Welder overheats.

Ensure the welder is not exceeding its duty cycle. Allow the welder to cool down if it overheats. Check the fan is working properly.

Erratic arc or sticking electrodes during ARC welding.

Ensure the electrode is compatible with the material being welded. Check the ground connection. Adjust the ARC force setting.

TIG torch not functioning.

Ensure the TIG torch is properly connected. Check the gas supply and flow rate. Check the tungsten electrode and ensure it is properly sharpened.
