Follow these steps to set up your Pretul Inverter Welder for operation.
- Yan Ibi to Dara: Select a dry, well-ventilated area free from flammable materials. Ensure stable footing for the welder.
- So Ilẹ Clamp: So ilẹ clamp cable to the negative (-) quick-change terminal on the welder. Securely attach the ground clamp to the workpiece or a clean, bare metal part of the welding table, ensuring good electrical contact.
- So ohun tí ó so mọ́ elekitirodu: For SMAW (stick welding), attach the electrode holder cable to the positive (+) quick-change terminal. Insert the appropriate electrode into the holder. For TIG welding, connect the TIG torch (not included) to the appropriate terminal and gas supply.
- Asopọ agbara: Ensure the welder's ON/OFF switch is in the OFF position. Plug the power cable into a suitable 127V or 220V electrical outlet. The welder will automatically detect and adapt to the input voltage.
- Mura silẹ fun Alurinmorin: Put on all necessary personal protective equipment (PPE), including a welding helmet, gloves, and protective clothing.
