Introduction And Specifications

General overview:
ARC-130 from GUOZHI is a DC stick purpose unit, designed for portable repair work and small project use. It is ideal for the welding enthusiast or hobbyist with basic nonaluminum repair needs and general light welding requirements. The ARC-130 features a lightweight IGBT inverter design and can provide capable service for small projects and repairs. NOTE: This unit is not suitable for welding aluminum.

General Use and Care :

• Care should be taken to keep the unit out of direct contact with water spray. The unit is rated IP21S, which rates it for light contact with dripping water but should never be used in the presence of water for safety. It is a good idea to remove the welder from the vicinity of any water or moisture source to reduce the possibility of electrocution or shock. Never operate in standing water.

• Every 1-2 months, depending upon use, the welder should be unplugged, opened up and carefully cleaned with compressed air. Regular maintenance will extend the life of the unit.
  IMPORTANT: Before opening the unit’s case for any reason, make sure the unit has been unplugged for at least 10 minutes to allow time for the capacitors to fully discharge. Severe shock and/or death could occur.

• Do not restrict air flow or movement of air around the welder. Allow a buffer distance of 2 ft from all sides if possible, with a minimum distance of at least 18″ clearance. Do not operate the welder immediately in the weld area or the force of the fan will cause welding issues such as unstable arc, or porosity.

• Do not mount in areas that are prone to severe shock or vibration. Lift and carry the welder by the shoulder strap.

• Do not direct metallic dust or any dirt intentionally toward the machine, particularly in grinding and welding operations. Make sure the panel is protected from damage during welding operations.

Duty Cycle.

• This unit can be described as a general purpose, do it yourself type of multi process unit and is intended for hobby use and general small repair and build activities. Care should be taken not toexceed the duty cycle limit of the ARC-130 for maximum servicelife.
• Once the duty cycle has been exceeded, heat may continue to build in the electronics. The duty cycle is based off a 10 minute duty cycle rating at 40° C. This means that the unit is capable of being operated at the maximum amps for the stated percent of time out of 10 minutes without a cool down break. For the balance of the 10 minute time period, the welder should rest without welding for maximum service life. The temperature light will come on and the welder will automatically stop welding when an overheat condition has occurred. If this occurs, stop and allow the unit to cool while switched on. Heat will continue to be generated by and transferred to the electronics after welding has ceased. Welding in humid, or hot conditions can affect duty cycle as well. Do not turn off the overheated welder until it has safely cooled for at least 15 minutes. Once the overheated condition has had time to clear, cycle the power switch off and back on to reset the unit. Do not operate the welder with the covers removed. The duty cycles are rated at maximum amps and are as follows:
  115V:Stick @ 60%

Over Current.

• Over currents can occur if there is a fault in the power supply system or inside the unit. If this occurs, and the LED lights up, turn the unit off, check for external causes and remedy the problem. If none is found, cycle the power switch off and then back on.
• This manual has been compiled to give an overview of operation and is designed to offer information centered around safe, practical use of the welder. Welding is inherently dangerous. Only the operator of this welder, can ensure that safe operating practices are followed,through the exercise of common sense practices and training. Do not operate this machine until you have fully read the manual, including the safety section.

Quick Setup And Use Guide

Stick Welding (ARC)
First determine the proper electrode polarity for the electrode to be used. Consult the electrode data for this information. Then connect the output cables to the output terminals of the machine for the selected polarity. Shown here is the connection method for DC(+) welding.

START STICK OPERATION

• Connect the electrode cable to the (+) terminal and the work clamp to the -) terminal. Insert the connector with the key lining up with the keyway and rotate approximately ¼ turn clockwise. Do not over tighten.
• For DC(-) welding, switch the cable connections at the machine so that the electrode cable is connected to (-) and the work clamp is connected to (+).

STICK OPERATION

1. Turn on the power switch on the rear of the unit. Allow unit to cycle through its start up program.
2. Select the Stick mode with the Stick selector switch.
3. Make sure electrode holder is connected to the positive connector and the work clamp is connected to the negative connector.
4. Select the desired amperage. Use the electrode diameter selection chart in this manual to determine the approximate range of amps suitable for the rod size selected. Consult the welding electrode manufacturer’s recommendation for proper amperage range. Each manufacturer has specific recommendations for its electrodes. Ultimately Amperage is determined by the electrode thickness and the thickness of the metal.
5. Strike the arc with either the tapping method or the match strike method. Beginners usually find that the match strike method yields best results. Professionals tend to gravitate toward the tapping method because of its placement accuracy which helps prevent arc striking outside of the weld zone.

Operating Precautions

• Operating Environment

1. The machine can perform in environments where conditions are dry with a max humidity of 60%.
2. Ambient temperature should be between -10 to +40 degrees centigrade.
3. Avoid operating machine in direct sunshine, rain, or snow.
4. Avoid operating the machine in environments where there is pollution or high concentrations of dust or corrosiveness gas in the air.

• Proper Ventilation
  All users must ensure proper ventilation of the machine. The machine is powerful and compact which generates high currents and heat. Wind alone cannot ensure proper cooling so it is advisable to place a fan to cool down the machine during hot weather or continuous usage in order to keep the components working for a long shelf life. Make sure the machines vents or built machine at a minimum of 30cm from any objects to ensure proper ventilation.

• Avoid Over voltage
  The specific power voltage can be found in the main technical specification chart listed above or on the rear plate of the machine. The automatic voltage compensation circuit will ensure that the current is functioning in the correct range. If the power voltage is exceeded from the max allowed value it will damage the components of the machine.

• Avoid Over loading
  Limit the current strictly to the max allowable duty cycle. Do not exceed the max load because overloading can damage and burn up the machine.

• Duty Cycle

  • Duty cycle refers to the percentage of the working time against a 10-minute work cycle. For example, if the machine has a 60% duty cycle at 40A this means you can run the machine at 40A for 6 min in a 10 min work cycle.
  • The remaining 4 minutes will be needed to let the machine cool down. If the current decreases, the duty cycle will increase and vice versa.
  • Do not operate over the recommended duty cycle of the machines or damage will occur to the machine that is irreversible. When output exceeds the duty cycle limit, the temperature within the machine will rise and the protective circuit will cut off the power source output. The power output will then resume operation only when the equipment has cooled down to normal temperature.
    Note: Continuous overload operation will damage the power source. In these cases, the damage is not covered by warranty repair.25℃| STICK
