- Main Power Switch: Turns the welder on or off.
- Gas Input: Connection point for the shielding gas hose (for MIG Gas welding).
- Power Cord: Integrated 220V power cord with US standard plug (NEMA 6-50P).
- Cooling Fan: Ensures proper ventilation and prevents overheating.
5. Setup
5.1 Power Connection
The Reboot RBM-1450 operates on a 220V AC power supply. Ensure your power source meets these requirements and that a 30A breaker is suggested for 220V operation.
- Connect the welder's power cord (220V 50A 6-50P plug) to a suitable 220V outlet.
- Ensure the main power switch on the rear of the unit is in the "OFF" position before connecting to power.
5.2 Wire Spool Installation (MIG Welding)
Figure 5.1: Illustration of how to install the wire spool inside the welder's wire feed compartment.
- Open the wire feed compartment cover.
- Place the wire spool onto the spool holder, ensuring it rotates freely.
- Feed the welding wire through the guide tube and into the drive rollers.
- Close the drive roller tension arm and adjust the tension appropriately. The wire should feed smoothly without slipping or deforming.
- Close the wire feed compartment cover.
5.3 Connecting Welding Cables
- For Stick (MMA) Welding:
- Connect the electrode holder cable to the positive (+) terminal.
- Connect the ground clamp cable to the negative (-) terminal.
- Attach the ground clamp securely to the workpiece or welding table.
- For Lift TIG Welding:
- Connect the TIG torch (if not integrated) to the negative (-) terminal.
- Connect the ground clamp cable to the positive (+) terminal.
- Attach the ground clamp securely to the workpiece or welding table.
- Connect the gas hose from the TIG torch to the gas input on the rear panel, and then to your argon gas cylinder.
- For MIG Welding (Gas/Gasless):
- The MIG torch is integrated.
- For Gas MIG, connect the gas hose from the rear panel to your shielding gas cylinder (e.g., CO2 or Argon/CO2 mix).
- Connect the ground clamp cable to the appropriate terminal based on your wire type (check manual for specific polarity for flux core vs. solid wire). Typically, for flux core, the ground clamp connects to the positive (+) terminal, and for solid wire with gas, it connects to the negative (-) terminal.
- Attach the ground clamp securely to the workpiece or welding table.
6. Operation
The RBM-1450 offers multiple welding processes. Select the appropriate mode and settings for your application.
Figure 6.1: Visual representation of the four welding processes supported: MIG Gas, MIG Gasless, Stick, and Lift TIG.
6.1 Selecting Welding Process
Use the process selection switch on the front panel to choose between MIG, Lift TIG, or Stick welding.
Figure 6.2: Close-up of the control panel highlighting the current/voltage adjustment knob and wire diameter selection switch.
6.2 Adjusting Welding Parameters
- Current/Voltage Knob: Rotate this knob to adjust the welding output. Higher numbers typically mean higher current/voltage.
- Wire Diameter Switch (MIG only): Select the setting that matches the diameter of the welding wire you are using (0.6mm, 0.8mm, or 0.9/1.0mm).
6.3 Welding Process Specifics
- Stick (MMA) Welding:
- Suitable for 2.5mm (3/32") 6013 and 7018 rods. Can also handle 3.2mm (1/8") 7018 rods on 220V.
- Set the current based on the electrode type and thickness of the material.
- MIG Welding (Gas/Gasless):
- For Gas MIG, ensure gas flow is set correctly at the regulator.
- For Gasless MIG, use flux-cored wire and ensure correct polarity.
- Adjust voltage and wire feed speed (controlled synergically by the machine) for optimal arc.
- Lift TIG Welding:
- Requires a TIG torch and pure argon shielding gas.
- To initiate arc, touch the tungsten electrode to the workpiece and then lift slightly.
