1.0 INTRODUCTION  

Your new stud welding equipment has been carefully con-
structed using the finest components and material available. 
Used properly, this equipment will give you many years of 
profitable, efficient service.  

The system incorporates the latest in engineering advances for 
complete, reliable end welding of mild steel, stainless steel 
and aluminum fasteners.  

A careful study of this manual will enable you to understand 
how the welder operates to insure proper performance under 
all conditions.  

2.0 WARRANTY   

          The electrical and mechanical components of the stud 

welder are thoroughly performance inspected prior to assem-
bly in the welder. The assembled welder is completely per-
formance checked. The welder is delivered to you in func-
tional electro-mechanical condition.   

          All parts used in the assembly of the welder and its ac-

cessories are fully warranted for a period of 1 YEAR from the 
date of delivery. In addition, the welding capacitors are war-
ranted for a period of 1 YEAR from the date of delivery. The 
printed circuit boards used in all proweld equipment are war-
ranted for a period of 3 years.   

          Under the warranty, the manufacturer reserves the right 

to repair or replace, at their option, defective parts which fail 
during the guarantee period. Notice of any claim for warranty 
repair or replacement must be furnished to the manufacturer 
by the purchaser within ten (10) days after the defect is first 
discovered. The manufacturer does not assume any liability 
for paying shipping cost or any labor or materials furnished 
where such cost are not expressly authorized in writing.   

          The manufacturer does not warrant any parts or acces-

sories against failures resulting from misuse, abuse, improper 
installation, maladjustment, or use not in accordance with the 
operating instructions furnished by the manufacturer. The 
warranty is valid only when studs are purchased from sources 
approved by the manufacturer or are of identical specifica-
tions to the manufacturer’s   

3.0 UNPACKING YOUR UNIT  

Upon receipt of your unit, place it as close as possible to the 
point of installation before unpacking it. Once the unit is un-
packed, it is recommended that you inspect it for any physical 
damage that may have occurred in shipping. 

Your unit has been completely assembled and inspected at 
the factory. Upon receipt, the unit must be hooked up to the 
recommended incoming power before welding.  

Place the unit in a large enough area to provide adequate ven-
tilation. Do not restrict the air flow around the front louvers 
or from the fan at the rear of the unit. Do not allow water to 
enter the unit in any way.   

4.0 SUGGESTED SAFETY PRECAUTIONS  

In any welding operation, it is the responsibility of the welder 
to observe all safety rules to insure his or her personal safety 
and to protect those working in the area.  

Reference is directed without endorsement or recommenda-
tion to ANSI Z49.1, Safety in Welding and Cutting, and to 
AWG Publication A6,1-66, Recommended Safe Practices for 
Gas-Shielded Arc Welding.  

4.1 Personal Safety Precautions  

1. Always treat electricity with respect. Under open circuit 
conditions, the welding machines output voltage may be dan-
gerous.  

2. Don’t work on live circuits or conductors. Disconnect the 
main power before checking the machine or performing any 
maintenance or repair operations.  

3. Be sure the welding machine cabinet is properly grounded 
to a good electrical ground. Consult local electrical codes.  

4. Never operate a welder in the rain, or operate a welder 
while standing in water. Avoid wearing wet or sweaty clothes 
when welding.  

5. Don’t operate with worn or poorly connected cables, and 
don’t operate the weld gun with loose cable connections. In-
spect all cables frequently for insulation failures, exposed 
wires, loose connections and repair as needed.  

6. Don’t overload welding cables or continue to operate with 
over heated cables.  

7. Don’t weld near flammable materials or liquids in or near 
the area, or on ducts or pipes carrying explosive gases.  

8. Don’t weld on containers which have held combustible or 
flammable materials, or on materials which give off flamma-
ble or toxic vapors when heated.
