IW/IW+ Preventive Maintenance

WARNING
The following preventive measures help assure long term operation of your Branson 2000
Series equipment.
7.1.1 Periodic Maintenance Procedures
Periodic maintenance for the welder involves:
• Inspecting the mating surfaces of the Converter-Booster-Horn Stack. If these surfaces become
corroded, recondition the surfaces by following the instructions in the following Section
• Inspecting and cleaning Air Filter components
• External covers may be cleaned with a damp sponge or cloth using a solution of mild soap and
water. Do not allow cleaning solution to enter the unit
7.1.2 Reconditioning the Stack (Converter, Booster and Horn)
Welding system components work most efficiently when the Converter-Booster-Horn
Stack mating surfaces are flat, in solid contact, and free from fretting corrosion. Poor
contact between mating surfaces wastes power output, makes tuning difficult, increases
noise and heat, and may cause damage to the converter.
For standard 20 kHz products, a Branson Mylar® washer should be installed between the
horn and booster, and horn and converter. Replace the washer if torn or perforated. Stacks
using Mylar washers should be inspected every three months.
