3. General Description
WD400A/500/1000E Welding Workstation is a fully-enclosed compact unit; it’s a diesel power generator and 
welder combined machine with dual holder, with multi-functional features. In order to meet the requirements for oil 
and gas pipe welding, the welding power source should be functionally capable of welding with low-hydrogen 
electrode, cellulose down-hill welding, flux-cored non-gas-shielded welding, and argon arc welding function. The 
flux-cored non-gas-shielded welding mode can not only use the TSS FCAW-501 Flux-cored Wire Feeder, it can 
also conveniently interface with Miller and Lincoln wire feeders (LN-23P or LN-25P, or 12VS, optional). The 
auxiliary power supply can output 50hz 3~400V 16kw (WD400) ,22KW(WD500) ,36kw(WD1000E) and 50hz 
single phase 1~230V/6.9KW (WD400A/500 ) 
，
1~230V/9.2KW (WD1000E). 
Technical characteristics of WD400A/500/1000E Welding Workstation: 

One set of independent power-frequency generator with sufficient auxiliary power output. 
AC power output one phase 1~230v *15A+ 1~230V*15A 6.9kw with two IEC standard receptacle 
for WD400A/500, one phase 1~230v *20A+ 1~230V*20A 9.2kw with two IEC standard receptacle 
for WD1000E; AC power output three phase 3~400v 16kw(WD400A) ,22kw(WD500), 
36KW(WD1000E) with one IEC standard industrial receptacle, 

Weichai 4-cylinder water-cooled 1500rpm industrial diesel engine is used as the source of power; 
Meanwhile, the diesel engine is equipped with electronic speed-control system, which is easy to 
adjust the engine speed and it is very stability with fast response to the any load. 

The engine oil pressure, water temperature, battery voltage charging, diesel fuel level and other 
parameters are individually displayed by using their display gauges or warning lamp indicator,

operator is easy to have a clear indication of the monitoring parameters and state of the engine,

IGBT inverter soft switch and negative feedback control technologies are used for ensuring good 
dynamic performance and welding performance as well as high load duration within full voltage 
regulating range and full current regulating range. The machine is provided with TIG, low hydrogen, 
cellulose, self-shielded flux-cored arc welding functions and can be connected to Lincoln, Miller, 
and ELAMN wire feeders.

It is provided with the function of presetting the current, voltage (optional)with a digital display 
meter, which can display preset and actual current and voltage.

It is equipped with dual welder, Single or two people operation can be chosen. when dual operation 
for WD500 ,two welder can output 2 x 300A /32V ,it can do
Φ
1.6—6.0 electrode welding 
simultaneously ,when single operation ,the welder can output 30—500A . when four welder 
operation for WD1000E , four welder can output 4*250A/30V, it can weld 
Φ
1.6—5.0 electrode 
welding simultaneously. 

The welding power source is provided with under voltage protection function. (when the voltage is 
under 280v AC, the welder can not work ,it will be normal until the voltage return to above 
300vac ,the normal voltage is 400v AC)
