WSE Series DC/AC Manual Wolfram Argon Arc Welding Machine

  This series adopts W-CE electrode with argon as protective medium. It is AD and DC universal argon arc welding machines. It has four functions of use: AC TIG welding, DC TIG welding, AC manual arc welding and DC manual arc welding. It can weld high, mid or low carbon steel, non-ferrous metals and its alloy. It has such properties as wide applying range, easy operation, stable and reliable performance.      

First. The main purpose and the scope of application

WSE AC and DC welding machine by using tungsten electrode in argon atmosphere for the protection of media, use AC or DC arc welding machine for welding. Welder can be welded carbon steel, stainless steel, alloy steel, copper, aluminum and other more active resistance to high temperature and chemical properties of metallic materials. acidic or alkaline can be used for manual welding electrode. 380V,50Hz welder using single-phase AC power.

Third. The principle and structure outlined

Welder used moving core transformer, the full-wave bridge and rectifier filter inductance is  output characteristics, so that the filter inductor DC welding output, the current stability in exchange output, the current zero speed.

By welding transformer, control transformer, single-phase rectifier bridge, filter inductance, capacitance at DSS. High-frequency oscillator, transformers, circuit boards and control solenoid valve, the gun and various switches.

The aircraft is equipped with a current figure panel installation instructions, explicit instructions welding current values. Welder shell shape is beautiful, strong, durable facilitate disassembly, lifting and transfer characteristics.

The stability and resumption arc is that the crater fill function that can significantly improve the quality of welding.

Fourth. The use and operation

  4.1 Welder only allowed to use at ambient temperature 5-40C, relative humidity of less than 90%. not to allow harmful gases, flammable and near the desert, steam spray, mold and other occasions. also prohibited conductivity dust.

4.2Welder must have good grounding, earthing wire cross-sectional area larger than the cross-sectional area of importation.

4.3 Welding power supply from the power grid, power and welding equipment should control switch. fuse should be consistent with the machine, welding output line will have to be good insulation and attention to the plane in line with the supply voltage.

4.4 When the welder used to extend the distance from the welding site welding cables, welding cables must be increased cross-sectional area. welding cable voltage drop is less than four voltage, burning arc stability can affect the quality of welding.

4.5 Welding operators to be trained professionally familiar with the technical requirements for the safe operation of aircraft and equipment, Safety must wear protective equipment, visual arc not prevent electroslag spatter, so as to avoid adverse consequences.

4.6 Finishing work or leaving the workplace, must be cut off the power.

4.8 Operating procedures

4.8.1 Using Tungsten Inert Gas (TIG)

  A. According to the brochure 4.7, gas road and the lines are connected all the good.

B. Face knob and switch to a suitable location, AC-DC switch must grant place.

C. According to the current requirements, the use of regulatory shake regard to the appropriate location adjustment instructions.

D. Power Switch appropriated to the "open" position when the power lights, rotating fans. Fans will not be diverted, repair and inspection of stands, not to use.

E. Frederick Frederick gas income into position switch to gas, argon gas flow adjustment flowmeter instructions, Switch will be adjusted income into working position.

F. Work.

4.8.2 Use SMAW

A. The statement by wiring, welding guns will be removed, to take over the welding tongs.

B. Switch on the panel will be transferred to the required location.

C. Regulation shake regard, the spin current direction of the required position.

D. Switching power supply will be allocated, the bright light, rotating fans, a no-load output voltage. Fans will not be diverted, not to use.

E. Started welding.

Fifth. repair and maintenance

5.1 Welding machine during maintenance or repair, we should cut off the power supply.

5.2 Welder regular internal cleansing, casing removed, and air dry cleaning internal components, parts.

5.3 Factory welder has been transferred to the best electrical sparks up, the use of such high frequency sparks decline easy arc starting, it would be appropriate to adjust the electrical sparks up the gap, reaching arc in the best condition. inspection of the main circuit and high-frequency oscillation circuit connection and prevent Pretend welding, Sealing-off phenomenon.

5.4 Welding cable insulation must regularly check whether good, if damage to be repaired or replaced.
