Introduction
General Description
PRESTOTIG 200 AC/DC machine is designated to
performe MMA (SMAW) and TIG (GTAW) welding
process in DC and AC current.
Unit is designed mainly to satisfy TIG requestes in both
DC and AC mode: thanks an advance menu options both
beginners and experts welder can adjust welding
parameters to have the best welding performances.
Following paragraphs will show how to access to the
menu and the parameters tha can be set.
The following equipment has been added to
PRESTOTIG 200 AC/DC :

Recommended equipment, which can be bought by user,
was mentioned in the "Suggested Accessories " section.
Installation and Operator Instructions
Read this entire section before installation or operation of
the machine.
Location and Environment
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.

Do not place or operate this machine on a surface with
an incline greater than 15° from horizontal.

Do not use this machine for pipe thawing.

This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover the
machine with paper, cloth or rags when switched on.

Dirt and dust that can be drawn into the machine
should be kept to a minimum.

This machine has a protection rating of IP23. Keep it
dry when possible and do not place it on wet ground
or in puddles.

Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.

Do not operate in areas with an ambient temperature
greater than 40°C.
Input Supply Connection
Check the input voltage, phase, and frequency supplied to
this machine before turning it on. The allowable input
voltage is indicated in the technical specification section of
this manual and on the rating plate of the machine. Be
sure that the machine is grounded.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. The fuse rating and cable sizes are both
indicated in the "Technical Specification" section of this
manual.
The machines are designed to operate on engine driven
generators as long as the auxiliary can supply adequate
voltage, frequency and power as indicated in the
"Technical Specification" section of this manual. The
auxiliary supply of the generator must also meet the
following conditions:
230Vac 1 phases:

Vac peak voltage: below 280V

Vac frequency: in the range of 50 and 60Hz

RMS voltage of the AC waveform: 230Vac ± 15%
115Vac 1 phases:

Vac frequency: in the range of 50 and 60Hz

RMS voltage of the AC waveform: 115Vac ± 15%
Note:
if connected @ 115Vac the equipment has output
derating It is important to check these conditions
because many engine driven generators produce high
voltage spikes. Operation of this machine on engine
driven generators not conforming to these conditions is
not recommended and may damage the machine.
Caution: To provide fully performance of duty cycle You
need to change overcurrent protection for 25A type D
and change for a proper input plug (or connect directly to
a power network)
