New Circuitry Incorporated into ARCON’S
1200 Amp Studwelder

ARCON has enhanced the design circuitry of the Studhorse 1200 in several areas for 2005 models. These new circuits include:

PILOT CURRENT

The pilot Current circuit:

1. helps to prevent sticking of the stud to parent material.
2. helps to melt the aluminum ball (flux) prior to full current.

Pilot Current is the solution to performing successful welds on surfaces that are not ideally cleaned and prepared. This circuit ensures that the arc begins at the center (tip) of the stud and progresses outward and it protects against the stud sticking prematurely sticking to the base metal.

To accomplish this, a pilot current is applied before the gun begins to lift is normally begins to lift the stud. When the pilot current cycle ends, the welder then defaults to the Current set on the control panel.

KICK START

The Kick Start circuit ensures that the lift cycle occurs at the proper time. This is especially important because of normal wear to the gun mechanism and the variation of stud sizes and diameters. To accomplish this, the welder provides an additional pulse to the stud gun coil to help ensure that the gun lift is within the required time frame. The welder automatically returns to the normal holding Voltage at the conclusion of the Kick Start cycle.

AFTER BURN

The After Burn Circuit is designed to eliminate crystallization in the weld by keeping the puddle molten for an additional period of time. This is very important when welding smaller (1/4”) studs. After Burn is instrumental in making a good weld by keeping the puddle hot for a longer period during the plunge cycle.


CURRENT/TIME CONTROLLED COOLING FAN

This new circuitry allows the fan to run only when the machine is welding and not constantly. This feature is necessary to reduce the amount of dust being pulled inside the welder. This reduces the frequency of maintenance, prevents debris from collecting on horizontal surfaces that can cause electrical arc-over between components, and also saves energy.
