SAFETY

PRECAUTIONS

• Comply with all electrical, fire and other applicable codes or ordinances

in the installation and use of stud welding systems.

• Remove all combustible or volatile materials from the weld area.

Although weld splatter resulting from stud welding is normally minimal,
proper precautions should be taken when welding near or through
combustible materials to insure that sparks or weld material do not come
in contact with combustible material.

• Recommend wearing of eye protection at all times when welding.

Spectacle type frames with Shade No. 3 absorptive and filter lens and
side shields are suggested. Never look directly at the weld arc without
wearing eye shields.

• Recommend use of proper ear protection with all CAPACITOR

DISCHARGE stud welding systems. The stud welding operator and
anyone working within five (5) feet of the stud welding operation should
use ear protection devices.

• Use of protective clothing is suggested. Type of clothing will vary as to

application, weld position and stud welding being used; however, in all
cases, it should be fire resistant and sufficient to protect welding
operator from weld splatter and material.

• Keep hands, clothing, etc. away from the weld stud, chuck and all other

parts in contact with them during the weld cycle.

• Keep weld cable and connectors in good condition. Inspect periodically

for broken insulation and/or other electrical hazards.

• Do not operate with worn or poorly connected cables. Inspect all cables

often for bare or exposed wires, broken insulation layers and/or loose
connections. Repair all such connections before welding use.

• Do not stand in water or on damp surfaces while welding. Avoid wearing

wet or sweaty clothes. Do not weld in the rain.

WARNING

Use extreme caution when servicing or troubleshooting

any component of this stud welding system.

If possible, turn all power controls 

“OFF”

and disconnect all electrical cables.

For other suggested precautions, safe practices, etc.

regarding welding, refer to

“Safety in Welding and Cutting”,

ANSI Z49.1, American National Standards Institute.
