5- USE AND MAINTENANCE PRECAUTIONS
User training
Any operator of this machine should receive training adapted to its use in order to gain maximum performance from the
unit (e.g.: car body repair training).
Adjust the balancer’s spring tension
Adjust the balancer’s spring tension with the Allen key equipped. Do not leave the clamp hanging for a long time on the
balancer, as it would induce early wear out of this part. Do not let the clamp fall down repeatedly without holding it, as it
could damage the balancer.
Preparation of the work-piece:
Grind and clean the work-piece thoroughly before welding.
If protection is being used, ensure that the parts are conducting by testing a sample.
Single sided gun welding
Before repairing a car, check that the car manufacturer authorizes that welding process.
Cooling liquid level and efficiency
The cooling liquid level is important to ensure the unit functions correctly. The liquid level should always be between the
minimum and maximum levels indicated on the tank. Check the level and efficiency of the cooling liquid regularly, replace if
needed. It is recommended replacing the cooling liquid every 2 years.
Cleaning the pneumatic filter
Ensure the dehumidifier filter located at the back of the machine is cleaned regularly.
Generator maintenance
The maintenance and repair of the generator should only be carried out by a GYS technician. Any repair/maintenance made
to the generator by unauthorized personnel will invalidate the machine's warranty - GYS will not take responsibility for any
incident or accident under these circumstances.
Cleaning / replacement of welding tools and other items
All welding tools are consumable and will deteriorate during use.
To extend the lifespan and efficiency of the tools, ensure that they are inspected and cleaned regularly.
When using with the Pneumatic Clamp, check that the condition of the electrodes/CAPS (flats, rounded or beveled) is good.
If the condition is poor, clean with fine grain sandpaper, or replace (see reference on the machine).
When using with the gun, check the condition of the tools: star, single-point electrode, carbon electrode. Clean, or replace if
necessary.
Ensure the pneumatic filter is clean to prevent the machine overheating.
Replacement of the caps/electrodes:
♦
To ensure an efficient welding point, you need to replace the caps every 200 spots - remove the caps using the spanner.
(Ref. 050846)
♦
Use grease (ref: 050440) when replacing caps
♦
Caps type A (ref: 049987)
♦
Caps type F (ref: 049970)
♦
Caps beveled (ref: 049994)
Caution:
The caps must be perfectly aligned. To
check the electrode line, see change of arms on
pages 18 and 19.
