* Do not operate under water or more humid place. Attention * 410-PROTIG20 Welder are electric product whose spare parts is very tender, do not change or adjust with a rush otherwise the switch will be damaged. * Check the connection to see if the welder input and output cables are well connected, whether...
Page 3: Safety Check
* Inflammable or explosive materials are prohibited to access the job site. * Fumes and gases produced when welding are hazardous to health. Make sure to work in places where there are exhaust or ventilation facilities to keep fumes or emissions away from the breathing zone.

Control Adjustment The 410-PROTIG20 welder applies advanced IGBT(insulated gate bipolar transistor)and rapid recovery diode as it’s the main power piece of the power transformation and transfer, with which the arc can be minutely controlled. It is also assisted with gas pre-flow gas post-flow and non-contact high frequency pilot, all which contribute to the machine with the feature of high reliability and fast dynamic response speed and stable arc.

Page 6 HF Arc Pilot Description There is distinctive difference between the high frequency pilot and traditional pilot way. There is no need to pilot by through the connection between the Tungsten electrode and the work piece, instead, it ionizes the air by high voltage and high frequency pulse, then conducted by the ionized air so as to form arc.

Φ 3.0 Maintenance and Service The most distinctive difference of 410-PROTIG20 Welder with the traditional welder is that it mostly adopt modern electric apparatus with high level technology. It is among the list of high-tech products, as a result higher technical requirement is asked for the maintenance personnel. However there are very few spare parts for that type machine, so maintenance is not required very often except the routine cleaning.
