Duty Cycle; Maintenance / Advice - Contimac TIG 160 DC HF Manual De Usuario

Pedal (
Option ref.045682)
In all modes excluding « Spot » mode, the pedal control enables variation of the current from the minimum intensity
(DC : 10A / MMA : 10) to an intensity definied by the user.
,
In TIG mode the machine will only operate in two-stage welding (2T mode). The upslope and downslope are not
automatic, and are controlled by the User with the foot pedal.
In « Spot » mode, the pedal control replaces the torch trigger (the pedal position has no effect on the current).

DUTY CYCLE

The welding unit describes an output characteristic of a "constant current". The duty cycles following the norm
EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table below :
TIG 160 A DC
X% @ I max X% @ I max
21% 160A 15%
60% 100A 60%
100% 90A 100%
Note: The machines' duty cycle has been tested at room temperature (40°C) and has been determined by
simulation.

MAINTENANCE / ADVICE

Maintenance should only be carried out by a qualified person.
Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out maintenance
work. (DANGER High Voltage and Currents).
GYS recommends removing the steel cover 2 or 3 times a year to remove any excess dust. Take this opportunity
to have the electrical connections checked by a qualified person with an insulated tool.
Regularly check the condition of the power supply cord. If damaged, it will need to be replaced by the
manufacturer, its' after sales service or a qualified person.
Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
SAFETY
Arc welding can be dangerous and can cause serious and even fatal injuries.
Protect yourself and others.
Ensure the following safety precautions are taken:
Arc radiation
Rain, steam, damp

Protect yourself with a helmet fitted with filters in compliance with EN169 or EN 379.
Use your welding unit in a clean/dry environment (pollution factor ≤ 3), on a flat surface,
and more than one meter from the welding work-piece. Do not use in rain or snow.
This device must only be used with an earthed power supply. Do not touch high voltage
parts. Check that the power supply is suitable for this unit.
Ensure the unit is placed in a stable position to prevent the machine from falling onto
people/objects.
Wear protective
Wear protective gloves and a fire-proof apron.
Ensure other people keep a safe distance from the work area and do not look directly at
the welding arc.
Protect others by installing fire-proof protection walls.
Remove all flammable products from the work area. Do not work in presence of
flammable gases.
