4. OPERATION
WARNING!
PLEASE READ CHAPTER 1 REGARDING SAFETY
4.1 General Description
The 1200 Amp Studhorse power source combines time-proven technology with modern
technology to provide high-quality performance. The digitally controlled SCR type inverter is
very reliable in welding applications and capable of welding 5/8-inch full-base weld studs in a
variety of applications. Duty Cycle at 1200 Amps is 6 per minute using 5/8-inch studs. 30 Amp
Slo-Blow fuses provide protection for all input voltages.
4.2 Design Features
The Studhorse power source is designed to be portable and easily transported to provide many
benefits. No crane or special lifting devices are required to move or maintain the machine. The
machine provides Constant Power output with Inverter-smooth arc, incorporating digitally
controlled start/stop with no mechanical contactor. Other features include regulated output,
step-less weld power and time adjustment, short-circuit protection, automatic line voltage
protection and 5-zones of thermal protection.
4.3 Operational Controls and Settings
– also refer to Figure 4.1
4.3.1 Circuit Breaker (Power On/Off)
The Circuit Breaker serves as the main input power switch and located on the control panel
at the rear of the machine. Move the switch lever up to the ON position to start the machine.
The Power-On indicator light will show that input power is being supplied to the machine.
4.3.2 Digital Meter on The DT1200i model
The digital current and timer meter displays current when the push button toggle switch is
pushed once, and displays time when pushed in again.
After switching on the input power to the machine, the four-digit display shows the
operational mode PA. The display shows the actual Current for three seconds after each
Stud has been welded. The Current setting is displayed as ”(X)XXX” and actual Current is
displayed as ”(X)XXX”.
If display flashes, the machine has exceeded its temperature limits. Wait a few minutes until
the display has stopped flashing, and you can resume welding.
