5. Cyfarwyddiadau Gweithredu
5.1 Powering On and Basic Controls
- Turn on the main power switch located on the rear of the unit.
- The digital display on the front panel will illuminate.
- Use the control knob to select the desired welding process (SMAW or TIG) and adjust the current (Amperage). The digital control ensures maximum precision.
- The welder features automatic Cychwyn Poeth for easy arc ignition and ArcForce for a stable arc, even with challenging electrodes.
5.2 SMAW (Shielded Metal Arc Welding) / Electrode Welding
- Select the SMAW mode using the control panel.
- Insert the appropriate electrode into the electrode holder. The Rogue ES 245i supports electrodes up to 4 mm, including cellulose types.
- Set the current according to the electrode manufacturer's recommendations and the material thickness.
- Strike the arc carefully and maintain a consistent arc length and travel speed for optimal weld quality.
5.3 TIG (Tungsten Inert Gas) Welding
The Rogue ES 245i is capable of TIG welding for thin sheets. For TIG welding, additional equipment such as a TIG torch with gas valve and a shielding gas cylinder will be required (not included).
- Connect the TIG torch to the appropriate terminal (usually negative for DC TIG).
- Cysylltwch y ddaear clamp i'r darn gwaith.
- Connect the shielding gas hose to the TIG torch and open the gas cylinder valve.
- Select TIG mode on the welder and set the desired current.
- Initiate the arc using the scratch start method or a high-frequency start if your TIG torch supports it.
