Setup
1. Power Connection
Ensure the welder is connected to an appropriate power supply (110V or 220V) as indicated on the machine's specifications. Use a dedicated circuit if possible to avoid overloading.

2. Wire Installation
The RBM-2100D supports 2LB and 10LB wire spools. Ensure the wire is correctly loaded onto the D100/D200 roller and fed through the torch liner.

3. Gas Connection (for MIG Gas and Spool Gun)
For MIG Gas welding, connect your shielding gas cylinder (e.g., CO2 for solid wire, Argon for aluminum with spool gun) to the gas input on the rear of the machine using appropriate hoses and regulators.
Operating Modes
The RBM-2100D offers multiple welding modes. Select the desired mode using the Welding Mode Selection knob on the front panel.
1. MIG Welding (Gas/Gasless)
MIG welding is suitable for various metals including mild steel, stainless steel, and aluminum. Use solid wire with shielding gas for MIG Gas, or flux-cored wire without gas for MIG Gasless.

Video 2: Reboot MIG Welder 210A 110/220V Flux Core Welding. This video illustrates the flux core welding process, which does not require external shielding gas.
2. Stick Welding (MMA)
The machine supports stick electrodes up to 3.2mm (1/8"). It performs well with 7018 1/8" electrodes, and also with 6013 and 7018 3/32".
3. Lift TIG Welding
For Lift TIG welding, connect a TIG torch (not included) to the machine. This mode provides precise control for thinner materials.

4. Spool Gun Welding
The additional spool gun function (spool gun not included) offers improved performance for aluminum welding, reducing the inconvenience of frequent wire changes.

5. 2T/4T Operative Mode
The 2T/4T function allows for semi-automatic operation, reducing finger fatigue during extended welding sessions. In 2T mode, the trigger must be held down. In 4T mode, a single press starts the arc, and another press stops it.

Important Safety Information
Welding can be dangerous. Always ensure proper safety precautions are taken to prevent injury or damage. Read and understand all safety warnings and instructions before operating this equipment.
- Always wear appropriate personal protective equipment (PPE), including welding helmet, gloves, protective clothing, and safety shoes.
- Ensure adequate ventilation to avoid inhalation of welding fumes.
- Protect eyes and skin from arc rays.
- Do not operate in damp or wet conditions.
- Keep children and unauthorized personnel away from the welding area.
- Disconnect power before performing any maintenance or adjustments.
- Refer to local safety regulations and standards.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your welder.
- Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring power is disconnected.
- Cable Inspection: Inspect all cables, including welding cables, power cord, and torch leads, for any signs of damage, cuts, or fraying. Replace damaged cables immediately.
- Consumables: Regularly check and replace worn-out consumables such as contact tips, nozzles, and diffusers on the MIG torch, and tungsten electrodes for TIG welding.
- Wire Feeder: Keep the wire feeder mechanism clean and free of debris. Ensure the drive rollers are appropriate for the wire size and are properly tensioned.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output power | Power switch off; circuit breaker tripped; loose connections. | Turn on switch; reset breaker; check all connections. |
| Wire not feeding | Wire tangled; drive roller tension incorrect; wrong drive roller size; clogged liner. | Untangle wire; adjust tension; install correct roller; clean/replace liner. |
| Poor weld quality | Incorrect settings (voltage/current); improper gas flow; contaminated material; worn consumables. | Adjust settings; check gas supply/flow; clean workpiece; replace contact tip/nozzle. |
| Overheat indicator on | Exceeded duty cycle; poor ventilation. | Allow machine to cool down; ensure proper airflow around the unit. |
