Thank you for choosing Antech welding equipments.
Please read this manual carefully before the installation and operation of
the SCD series stud welding machine. Do not hesitate to contact us if you have
queries.
The SCD series of stud welding machines is another high quality product
developed by Antech Electronics Ltd. It is built with a dedicated AN-350
controller that provides stable outputs regardless of any input voltage and
temperature changes. The internal memory supports three (3, or up) set of program
parameters. The SCD series stud welding machines are equipped with either quality
German or Japanese stud welding guns to provide superb performance and
reliability. It is thus a perfect alternative to the expensive import stud
welding machines.
Please advise if any errors are found concerning the contents and printing
of this manual.

CAUTIONS
1. Ensure that the welding machine is properly grounded before operations, to
avoid electric shock.
2. Be aware of high voltage
The power thyristors, transformers, capacitors and some components might
carry high voltages. It is advised that the supply to the welding machine
be disconnected before opening the chassis for service and maintenance.
3. Ensure that the start switch or welding gun trigger is in the off position
before turning on the power to the welding machine.
4. Do not operate the welding machine if the chassis is open.
5. Any service, repairing and maintenance should only be performed by qualified
technicians. ( Be cautious when dealing with high voltage components, such
as the thyristers, transformers and capacitors )
6. The working environment should be free of corrosive gas, vapor and excessive
dust. Keep the control unit from contacts of water and grease.
7. Do not place heavy loads on top of the control unit.
8. Keep working condition clean, free of dust and dry. Check cable connections
and screw joints in a regular basis.
9. No smoking and fire hazardous material is near by the welding machine.
10. Sparks might be produced in the welding process. It is strongly recommended
that protection materials, especially safety glasses, be worn to prevent
bodily injuries.

1. INTRODUCTION:
The SCD series Stud Welding Machines are designed for tip ignition stud
welding of stud/nails. The stud weld is completed in a very short period of time.
This helps to prevent thin workpieces from damage and distortion due to the heat
generated during the welding process. As a result, the SCD series stud welding
is suitable for a wide range of applications.
It is easy to perform maintenance and repairing as all the major parts are
housed in a single chassis, except the welding gun and cables. Based on a lot
of expertise, experience and continuous improvements, the SCD series of stud
welding machines have been developed to meet the requirements of the welding
industry. It is suitable for the stud welding of stainless steel, mild steel,
aluminum, copper … etc.
It is our endeavor to maintain a high quality control policy so that our
products will satisfy all our users in the welding industry.

3.1.1 Place the welding machine on a solid and stable platform.
3.1.2 If necessary, u se a250VD.C.isolation meter to check the isolation between
the input power lines and the chassis. The resistance should be greater
than 2 MO .( due to t he internal electronics, the control circuit wiring
should be disconnected for proper measurement of isolation) .
3.1.3 Connect the input power plug to a suitable and safe power socket. Proper
grounding is mamdatory.
3.1.4 For pneumatic welding gun systems:
(1)Connect the pedal/push button switch to the connector on the front of
the control unit;
(2)Clean the air hoses and assembly, and then connect the air outlet from
the air-compressor to the air inlet on the right hand side of the
welding machine;
3.1.5 Output Power Selection:(to be set according to customer requirements)
There are three selections of output power ranges, as shown in Figure 1.
The selections can be made with the position of the copper bars at the
back of the control unit:

3.2 Exterior Connections:(See Figure 2)
3.2.1 Connect the stud welding gun cable to the corresponding( -) fast-on socket
at the left of the front panel of the welding machine. Turn right and ensure
that they are tightened properly;
3.2.2 Connect the control wires of the welding gun to the 4-pin socket on the
front of the control panel, tighten the connection with the mounting ring
of the plug;
3.2.3 Connect the earth cables to the earth( +) fast-on connector on the front
panel. Turn clockwise to tighten the connection properly;
3.2.4 Connect the earth cables to the work piece by clamps respectively.
? NOTE: 1.As welding current may go up to8000A, it is essential to maintain tight
connections for all welding gun and earth cables;
2.To achieve satisfactory welding results, use both earth cables for the
connection of the work piece. They should placed in a diagonal
positions, as shown in Figure 3;
