confined area.

10. Never look at the electric arc without wearing protective
eye shields.

11. Always use the proper protective clothing, gloves, etc.

12. Never strike an arc when near a bystander who is un-
aware of the dangers of ultraviolet light to their eyes.

4.2 POWER SUPPLY SAFETY PRECAUTIONS

1. Always connect the frame to the power supply to ground
in accordance with the National Electrical Code and the
manufacturer’s recommendations.

2. Installation, servicing, or trouble shooting should be done
by qualified personnel trained to work on this type of equip-
ment.

3. Before servicing this piece of equipment, turn off the dis-
connect switch at the fuse box.

4. When in operation, all the covers must be on the equip-
ment.

5.0 GENERAL DESCRIPTION

THE PROCESS

Stud welding is a time saving tool which semi-automatically
arc welds the FULL CROSS-SECTION of a weld stud to the
base material in a fraction of a second and develops superior
strength over normal arc welding procedures.

Since the ARC-800 stud welding system provides the proper
arc length and allows you to select the proper arc time and
welding current, the variables that affect weld quality are
minimized.

THE UNIT

The ARC-800 is a compact and portable stud welding power
supply capable of welding studs through 1/2” diameter weld
base. The power supply which operates on single phase
power has the added feature of weld current regulation that
improves stud welding consistency. Both the weld time and
weld current are infinitely adjustable for preciseness and re-
peatability
A specially designed electronic gun control circuit has been
incorporated in this system. If a fault condition occurs due to
a shorted gun solenoid or a faulty control cable, the circuit

This unit is equipped with input voltage jumper links either installed
or in a bag on the jumper link board to allow operation from different
line voltages. If installed, the jumper links are positioned for the high-
est voltage stated on the nameplate or on the input data label. In either
case the jumper links should always be checked to see if they are prop-
erly positioned for the voltage being used.

Open the access door located on the lower portion of the rear panel to
expose the jumper link board. If necessary, reposition the jumper links
to match the line voltage being used. (see Figure 1)

6.0 ELECTRICAL INPUT REQUIREMENT

This welding power source is designed to be operated from
single-phase, 60 Hertz, AC power supply which has a line
voltage rating that corresponds with one of the electrical in-
put voltage shown on the nameplate or input data label. Ade-
quate incoming power must be available to obtain maximum
performance.
The ARC-800 should be operated from a separate fused or
circuit breaker protected circuit. Install two primary leads
plus one ground wire (see table for proper wire and fuse
sizes) through the inlet hole in the rear of the unit, using
proper strain relief. The primary cables connect to terminals
L or line. A third lead (ground connection) should be fas-
tened to the terminal labeled “GND”. The other end the
ground lead or cable should be attached to a suitable ground
such as a water pipe, ground rod, ect.
Use whatever grounding means is acceptable to the local
electrical inspection authorities. Consult the local electric
utility if there is any question about the type of electrical sys-
tem available at the installation site or how proper connec-
tions to the welding power source are to be made.
