4.9 Compatible Equipment
4.9.1 Two-Wire Controlled Guns
The Nelweld power supply line is compatible
with two-wire welding guns employing Nelweld
Lift Technology
 .

Number
Standard Duty, Drawn Arc – NS40, two-wire 751-692-000
Short Cycle – NS40SC, two-wire
751-695-000
Heavy Duty – NS20AHD, two wire 751-693-000
Note that a three pin connector is used
even though welding guns only use two
wires.
4.9.2 Three- and Four-Wire Controlled Guns
Nelweld power sources are compatible with all
existing Nelson stud welding guns with three- and
four-wire control with the use of a converter.

4.10 Limitations
4.10.1 Duty Cycle
The duty cycle limits for the Nelweld 3000, 4000,
5000, and 6000 can be seen in the
Stud Weld Rate
table.
4.10.2 Weld Cable Length
The diameter and length of the weld cable limit
the amount of current that can be supplied to the
stud welding arc. For best performance, use the
largest diameter cable, only use as much cable
length as needed, bundle the gun and ground
cables together where practical, and do not coil
excess cable.
The following graphs define cable length limits
for each machine in the product line.
The total weld length includes the work lead.
Thus if welding with 200 feet of gun cable and
200 feet of ground cable, then the total cable
length is 400 feet
