      BX1 Series AC Arc Welding Machine

    The welding-machine of this series uses move-iron structure, which can weld parts of  steel of low carbon or low alloy. It can be  manipulated by only one person. Compared with ordinary welding machines using natural cooling method, the BX1-250BX1-315 and BX1-500 using forcing blast cooling method, therefore they have such advantages as light weight and more easily moved than natural cooling welding machine. The welding-machines of this series can be applied not only to mines or enterprises but also to medium and small sized repairs.     

First. attention to safety issues to avoid major personal accident, please observe the following :

1.1 Installation, use of the former welder, please read carefully the use of brochures, and to comply with the warning welder website content and language warning.

Especially in the welding or coated with the coating material, we will create harmful dust and gases, we must pay more attention to defense.

4.4 Welding in a confined place, the district should arrange for inspections of ventilation and staff Officers regularly check whether normal operations.

To prevent fire, explosion, bursting the accident occurred, the following provisions :

Spatter from the welding, welding slag, thermal contact with the workpiece will fuel fire.

power supply circuit, the welding circuit connecting Department should ensure good contact, otherwise the work will cause local overheating.

In the absence of effective preventive measures before the ban in sealed containers filled with a flammable substance or welding. otherwise it would cause an explosion or burst.

1.1 Welding worksite is not allowed with flammable, explosive or combustible materials.

2.2 Connection of the cables will be required reliable and good insulation.

3.3 When the welding or sealed container containing flammable material (such as pipes, boxes, beds, etc.). have to ask the expert to develop effective preventive measures can do welding.

4.4 In the welding field should be equipped with the necessary safety equipment, just in case.

Contact rotating parts will cause injuries, the following provisions :

       1.1 Please do not demolish the shell off, or other protective devices for the use of welding.

2.2 Not to fingers, clothes, hair and other parts of the rotation near the welder (such as cooling fan), to prevent injuries.

To prevent the welding machine and caused fire damage to the insulation properties, please observe the following rules :

1.1 Welder placed at the site to ensure welding spatter from the metal powder or other operations. metal shaving tablets into internal welder, who have found access, and ensure all of 7659, following the demolition of shell, blowing with compressed air or other methods to remove the net.

welder place :

  1.1 Welder should be placed in Steady, less vibration from the walls of not less than 20cm.

2.2 Welder should be placed in non-iron, less dust, clean dry place.

3.3 Prevent rain or water erosion.

welder link :

  1.1 Welder link should be professionals.

The initial and long-term use of the new place and then re-use the welder welding, wiring, Application Megger measuring between primary coil and coil, primary coil and coil insulation resistance between the frame with no low-1M.

2.2 Welder and overcurrent protection switches should be equipped with the exclusive distribution function boxes (board) , with the capacity to be used for welding match.

3.3 Connection between the start, has cut off power supply should be recognized.

4.4 Welder from the distribution box to recommend the use of the order on the beyond-visual input power cord soft PVC multiple Copper Wire; Another welder output from the workpiece (grounding clip) and the link between welding tongs should be used YH or YHF welding or special rubber insulated cables.

2.2 To ensure the normal life welder, according to the duty cycle welder and welder to avoid overload.Weld will set off a serious burn.

Welder rated duty cycle is a very important technical parameters, Weld said it rated in the actual welding current work in a welding cycle time (10 minutes) the percentage.

For example : Welder rated duty cycle of 60%, which is rated in Taiwan welder welding current, Welding allowed under six minutes, four minutes and then empty the recycling.

When the actual welding welding current is less than the rated current welder, welding time can be extended.Then load rate calculated by the following formula :

Allowable load sustained rate = (Rated welding current actual welding ) 2 rated duty cycle

3.3 Be connected to the welding joint firm, otherwise they will be barred from access to localized overheating and burning or welding cable connector.

4.4 Welding cables should not be longer than generally should not exceed 15m. As a result of actual needs to be lengthened, if welding arc welding current is too small or difficult situations, C and appropriate cables.

5.5 Welder prevent rain; To place in cool, dry ventilation, avoid moisture, with iron dust and placed in many places; In summer, not in use for long periods under direct sunshine.

6.6 Operators should wear protective safety complete welding supplies.

7.7 Or temporary work after leaving the scene, we must cut off the power supply box welder and distribution.

8.8 Weld should pay attention to the use of state, found abnormal, should immediately check stands, remove anomalies can continue its work.
