Thank you for choosing our product! In order to take the most of your welder, please read the following instructions carefully:
These Inverter's machines are portable, air cooled and made to weld electrode and TIG Lift in direct current (DC). It allows
welding with rutiles, basic, stainless steel, cast iron electrodes. In TIG, it allows to weld most of metals except aluminium and
alloys. It is protected for a use on electric generators (230V /+- 15%).
POWER SUPPLY – START UP
• The machines delivered with a 230V socket /16A plug type EEC7/7 must be plugged on a 230 V (50-60Hz) 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 intensive use, preferably select a 20 A plug for
the single phase products from 160A. The welder must be installed so that the mains plug is accessible.
• The start-up is done by pressing the ON / STAND BY.
• The device turns into protection mode if the power supply tension is over 265V for the single phase models (the screen
displays ). Once in protection mode, you have to unplug the device and plug it back on a socket delivering the correct
tension.
• These are A-class devices. They are designed to be used in an industrial or professional environment. In a different
environment, it can be difficult to ensure electromagnetic compatibility, due to conducted disturbances as well as radiation.
• JBDCmi IMS 170 is in accordance with the standard EN61000-3-11 if
the interface point of the user's supply
• These machines are not in accordance with the standard CEI 61000-3-12. Before connecting the unit to the public low
voltage network, the user must be sure that he is permitted to connect them.
• 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
(adjustable mode, see below) increases the current at the beginning of the welding.
The Arc Force
(adjustable mode, see below) 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.
Selection of MMA Mode and intensity setting :
- Select the MMA position  with the selector.
- Adjust the wished current (display ) using the key .
Hot Start & Arc Force adjustments
Advice : low Hot Start : for thin metal sheets – high Hot Start for metals that are difficult to weld
