Operating manual - EN 1.1 Equipment description Kemppi MasterTig 235 AC/DC, 325 DC and 335 AC/DC welding equipment is designed for professional industrial use, with characteristics especially suitable for welding materials like aluminum and stainless steel. The equipment con- sists of power source, control panel and cooling unit (optional). The MasterTig Cooler M cooling unit is used in liquid-cooled TIG welding with MasterTig power source.

Fill the cooling unit with cooling liquid. >> MasterTig Cooler M tank volume is 3 litres and the recommended coolant is MPG 4456 (Kemppi mixture). Avoid cooling liquid contact with skin or eyes. In case of an injury, seek for medical advice.
A suitable flow rate for argon is normally 5 – 15 l/min. If the gas flow is not correctly set, this will increase the risk of defects in the weld (weld porosity). Spark ignition becomes more difficult if the gas flow is too high. Contact your local Kemppi dealer for choosing the gas and the equipment. Gas bottle valve...

Remove the USB memory stick and install the control panel back in place. Refer to "Installing control panel" on page 9 for more information. To delete a custom screen saver image from the control panel memory, or to use the Kemppi logo instead, go to "Set- tings view" on page 46.
Check that all covers and components are intact. • Check all the cables and connectors. Do not use them if they are damaged. For repairs, contact Kemppi at www.kemppi.com or your dealer. Periodic maintenance Only an authorized electrician is allowed to carry out electrical work.
The owner of the equipment is obliged to deliver a decommissioned unit to a regional collection center, as per the instructions of local authorities or a Kemppi representative. By applying these European Directives you improve the environment and human health.
5. TROUBLESHOOTING The problems and the possible causes listed are not definitive, but suggest some typical situations that may turn up during normal use of the welding system. For further information and assistance, contact your nearest Kemppi service workshop. If you have received an error code, refer also to "Error codes" on the next page .
Too long welding session with high power or Do not turn off the cooler. Let the liquid circulate until the overheated high ambient temperature. fans cool it down. If fans are not running, contact Kemppi service. Cooling liquid No cooling liquid or circulation is blocked.
