ims PRO MMA 100P Mode D'emploi page 7

DESCRIPTION
Thank you for choosing our product ! To get the best of your equipment, please read carefully the following.
The 100P, 130P, 160P, 200P are portable, single-phase, air cooled Inverter welding units, for MMA electrode welding
with direct current (DC). They can weld all kind of electrodes : rutile, cast-iron, basic (except for 100P), stainless
steel. (They are over-voltage protected when used on power generators (230 V +- 15%)
POWER SUPPLY – START UP
• This machine is delivered with a 16A plug type EEC7/7. The machine must be plugged on a 230 V (50-60Hz)
socket with earth. The absorbed effective current (I1eff) is shown on the machine, for maximal using
conditions. Check that the power supply and its protection (fuse and/or circuit-breaker) is compatible with the
necessary current during use. In some countries, the change of plug can be necessary to allow a use at
maximal conditions. For the 130P in intensive use, preferably select a 25 A plug. For the 160P in intensive use,
preferably select a 25 A plug. For the 200P in intensive use, preferably select a 32 A plug. The charger must be
installed so that the mains plug is accessible.
• To start the equipment, turn on the potentiometer to the desired current position, the power indicator lights
then. Put the potentiometer on "O" for standby mode.
• Connect the earth clamp and electrode-holder cables in the quick-plugs. Respect the polarities indicated on the
electrode packaging.
•
This Class A equipment is not intended for use in residential locations where the electrical power is provided by
the public low-voltage supply system
compatibility in those locations, due to conducted as well as radiated disturbances.
•
These machines are in accordance with the standard EN61000-3-11 if
impedance Zmax at the interface point of the user's supply
This equipment does not comply with IEC 61000-3-12. If it is connected to a public low voltage
system, it is the responsibility of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if necessary, that the equipment may be
connected.
• Do not use the machine in an area containing metallic conducting dust.
ELECTRODE WELDING (MMA MODE)
• Apply the usual welding rules.
• Leave the machine connected to the supply after welding in order to let it cool down.
• Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min according
to external temperature.
• Your machine is equipped with 3 specific functions to Inverters :
The Hot Start increases the current at the beginning of the welding.
The Arc Force increases the current in order to avoid the sticking when electrode enters in melted
metal.
The Anti Sticking allows you to easily withdraw your electrode without damaging it in case of sticking.
The machines described have an output characteristic of 'constant current' type. The duty cycle are indicated in
the table below according to EN60974-1 Norm.

Note: the running hot tests have been carried out at atmosphere temperature and duty cycle has been
determined at 40°C by simulation.
TIG WELDING
This machine can be used in TIG mode with a scratch ignition
There may be potential difficulties in ensuring electromagnetic
