The Reboot ARC145 is an intelligent and user-friendly welding machine designed for manual welding, offering excellent welding performance, versatility across various scenarios, and superior welding results. It's highly regarded by welding enthusiasts and is also suitable for beginners due to its ease of use and quick learning curve.

Function Description:

The ARC145 is a stick welding machine that supports both AC 110V and AC 220V voltage input, making it adaptable to different power supplies. It features a clear digital display for preset current and indicators for power and fault conditions. The machine is equipped with a current adjustment knob for precise control over the welding process.

Key Components and Indicators:

  • Power Indicator Light (1): Illuminates when the machine is powered on.
  • Current Display Meter (2): Shows the currently preset welding current.
  • Fault Light (3): Activates under two conditions:
    • When the welding load is overloaded or the output current is excessively large (a normal situation, and the machine can recover).
    • When there is internal damage to the machine, indicating an abnormal condition requiring maintenance.
  • Current Adjustment Knob (4): Used to set the desired welding current.
  • Positive Connection (5): For installing the welding holder and grounding clamp.
  • Negative Connection (6): For installing the welding holder and grounding clamp.

Usage Features:

The ARC145 is designed for ease of use, even for beginners. It supports welding rods below 4.0mm (5/32in), with common sizes being 2.5mm (3/32in) and 3.2mm (1/8in). It's compatible with various electrode types:

  • European style: E6013
  • American style: E7018
  • Stainless steel: ER308

The machine can weld carbon steel with thicknesses ranging from 1-8mm (1/64-5/64in) and stainless steel from 1-5mm (1/64-7/32in). It is important to note that this machine cannot weld aluminum. For carbon steel, carbon steel electrodes should be used, and for stainless steel, stainless steel electrodes are required.

Operational Guidance:

  1. Connecting Accessories: Connect the welding holder and ground clamp to the respective positive and negative connections.
  2. Ground Clamp Connection: Ensure the ground clamp is connected to clean, bare metal, free from rust, paint, or other coatings, to ensure good electrical conductivity.
  3. Current Adjustment: Use the current adjustment knob to set the desired welding current.
  4. Welding Distance: Maintain an ideal distance of 1-2mm (1/64-5/64in) between the welding rod and the workpiece for continuous and stable contact. Avoid holding the rod too high or pressing too low to prevent arc breaking and adhesion.
  5. Arc Starting: For novices, adhesion during welding is common. Friction arc starting can help prevent this.
  6. Electrode Compatibility: Suitable for ordinary welding rods like 7018, 6013, but not for special welding rods such as 7010, 7011.

Power-on Precautions:

  1. Power Supply Voltage: Ensure your power supply voltage is 110V±15% or 220V±15%. The ARC145D supports both 110V and 220V input in North America and Japan, while the ARC145 supports 220V input in the UK, EU, and other regions. If using a generator, ensure it provides at least 4000W.
  2. Circuit Breaker Protection: A 50A circuit breaker is recommended for 110V power supply, and a 30A circuit breaker for 220V.
  3. Power Plug: Choose a power plug that complies with local electrical regulations.
  4. Extension Cord: Use a #12 AWG or larger extension cord, no longer than 25 feet (8m).

Upon powering on, the fan at the back of the machine should rotate, and the digital display on the panel should indicate normal operation. The fan may continue to rotate for a few seconds after power-off to reduce the machine's working temperature, which is normal.

Maintenance Features and Troubleshooting:

The ARC145 is designed with internal protection mechanisms. During high-strength continuous welding, the machine may enter protection mode, indicated by the "OC" light on the panel. After a period of heat dissipation, the machine will automatically return to normal operation.

Troubleshooting Common Issues:

  • No Arc:
    • Check if the ground wire is properly connected to the workpiece and if the workpiece is free of rust, paint, or other coatings.
    • Verify the distance between the welding rod and the workpiece (ideal is 1-2mm).
    • Ensure the welding object is clean; polish with sandpaper or a grinder if necessary.
  • OC Fault Light On During Welding: This indicates over-current protection. Stop welding, allow the machine to cool for a few minutes, and it should automatically recover. If it doesn't recover after 10 minutes, shut down and restart.
  • OC Light On When Machine is Turned On: Contact customer support.
  • Poor Welding Quality (large spatter, broken arc): Try exchanging the connection of the welding clamp and grounding clamp with the machine.
  • Machine Fails to Turn On (Power LED off):
    • Check for input voltage.
    • Inspect the supply plug or cable for faults.
    • An internal fuse might have tripped; allow time for auto-reset.
  • Thermal Overload (Thermal LED on):
    • The unit may have been operated beyond its capacity rating.
    • Airflow through the machine might be restricted, or the fan may have failed.

Internal Components (for maintenance reference):

  1. EMC Board: Isolates external power grid and internal circuits to prevent mutual interference.
  2. All-copper Main Transformer: Provides substantial power.
  3. High-power Large Capacitors: Enhance machine stability.
  4. Thicker Radiator: Ensures better heat dissipation.
  5. Imported IGBTs (4): Deliver stable and powerful current output.
  6. Imported Rectifier Tubes (3): Ensure stable and powerful current output.
