EXERCISE 12 : Soldering of PVC wire joint

Objectives

At the end of this exercise you shall be able to
• check & identify the rating of electric soldering iron
• skin the insulation of pvc copper wire and cleaning
• apply the flux & tinning of conductor of pvc wire
• perform the soldering on pvc copper wire and joints.

Requirements

Tools/Equipments
• Combination plier (165mm, insulated) - 1 No. Materials/Components
• Side cutting plier (150mm, insulated) - 1 No. • PVC copper wire
• Edge cutter (100 ssssmm) - 1 No. (1.5 sq.mm) - as reqd.
• Wire stripper (150 mm) - 1 No. • Soldering lead (Resin core) - 100 gm.
• Neon tester (75mm, insulated) - 1 No. • Soldering flux - as reqd.
• Soldering iron • Emery paper - as reqd.
(25 W & 60 W, 230 V) - 1 No each. • Insulation tape (19mm) - 1 role
• Soldering stand - 1 No.

Procedure

TASK 1: Identify and test the Electric soldering iron
1 Check the rating of Electric soldering iron and test it for heating.

2 Take two pieces of PVC copper wire and remove the insulation of 10mm with electrician knife.
3 Clean the tip of soldering iron with emery paper.

TASK 2: Perform the soldering on PVC copper wire & joints

1 Connect soldering iron to the supply and allow it to heat.
2 Clean the conductors of PVC copper wire with Electrician knife and make the tinning with soldering lead.
3 Hold the tinned copper conductors joined together and solder with soldering iron.
4 Insulate the soldered joint with insulation tape.
5 Practice the soldering on different types of wires and joints.
Safety precautions

• Do not make soldering without cleaning & tinning of conductors.
• Do not make loose and improper soldering.
• Don not touch the tip & metal part of soldering iron to avoid injury.
• Do not place the hot soldering iron wooden table, use soldering stand.

• Do not inhale the smoke during soldering, use exhaust fan while soldering
