4.4 Welding Operation
1. All secondary outputs must be connected to output terminals of the power source
2. After the primary input connections have been made, close the main wall disconnect
switch or circuit breaker.
3. Put the primary power selector in the ON position. This will turn on the control circuitry.
The Power-On light on the front panel will be lit.
4. Adjust the Welding Current Control and the Stud Timer Control to fit the type and
diameter of electrode to be used, according to the table below:
4.4.1 Begin welding utilizing Factory suggested Weld Set points
Recommended Current and Time Settings
Stud Size Current Time
Inches Metric (Amps) (Seconds)
1 / 4 (6mm) 450A 0.200
5 /16
(8mm) 550A 0.250
3 / 8
(10mm) 650A 0.350
1 / 2
(12mm) 850A 0.550
5 / 8
(16mm) 1200A 0.700
1. If 5/8-inch studs are to be welded, set the current timer to 1200 Amps and the timer
setting to 0.7 Seconds.
2. Shoot (weld) stud.
4.4.2 Digital Timer and Setting Operation for The DT1200i
Depending on the length of your welding and gun cables, the measured current may be 1250A.
This number will be displayed on the current display.
After 6 seconds, a steady current value of 1225 A will be displayed, which is the average
between set current and measured current.
The time and current settings will vary with the gun’s lift and plunge settings.
A good weld is characterized by an even ”flash” formation, a shiny, bluish tint to the flash
surface, a slight flow of flash metal into the base material, good flash height, consistant stud
length after the weld and a full circle flash around the stud circumfirence after the weld.
