Troubleshooting - TIG Weld Quality (Continued)
Fault Cause Remedy
Arc difficult to start or will not
start welding
Incorrect machine set up Check machine set up is correct
No gas, incorrect gas flow
Check the gas is connected and cylinder valve open, check hoses, gas
valve and torch are not restricted. Set the gas flow between 10 - 15 l/min
Tungsten is contaminated Remove 10mm of contaminated tungsten and re grind the tungsten
Incorrect tungsten size and or tungsten
being used
Check and change the size and or the tungsten if required
Loose connection Check all connectors and tighten
Earth clamp not connected to work Connect the earth clamp directly to the work piece wherever possible
Loss of high frequency
Check torch and cables for cracked insulation or bad connections. Check
spark gaps and adjust if necessary
MACHINE CARE & MAINTENANCE
WARNING!
BEFORE REPLACING CABLES / CONNECTIONS MAKE SURE THE WELDING MACHINE IS SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY OUTLET.
Ensure the items are disconnected from the electrical supply and cannot operate accidentally when, servicing or cleaning.
The machine does not require any special maintenance; however the user must be aware of the following:
• Regularly clean the ventilation slots.
• Keep the casing clean.
• Check all cables before use.
• Check electrode holders, work lead/clamps and welding torches before use.
• Replace worn electrode holders and earth clamps, which do not provide a good connection.
• Replace worn consumable parts in a timely manner.
• Replace worn wire drive rollers in a timely manner
• Use a soft cloth or brush to clean electrical components. Do not use liquid cleaning products, water or especially solvents.
• Do not use compressed air to clean electrical components as this can force dirt and dust further into components, causing electrical short circuits.
Check for damaged parts
Do not use the welder with damaged parts, before further use a damaged welder must be carefully checked by a qualified person to determine that it will operate
properly. Check for breakage of parts, mountings and other conditions that may affect its operation. An authorised service centre should properly repair a damaged
part.
Have your welder repaired by an expert
This
appliance is manufactured in accordance with relevant safety standards. Only experts must carry out repairing of electrical appliances, otherwise considerable
danger for the user may result. Use only genuine replacement parts, which are available from your nearest Weldtech store. Do not use modified or non-genuine
parts.
Storing the Welder
When not in use the welder should be stored in the dry, out of reach of children and in a frost-free environment.
