Brief Description - JESS Welding Jackle MIG 296 Betriebsanleitung

1. Brief description

The welding units MIG 296 / 326 / 406 / 506 have been developed for industry use. This is why their equipment
and the way of functioning have been designed for professional use.
Solid construction
The power source is housed in a solid sheet steel casing with large wheels making it easy to move. Switches
and control elements are accommodated in a separate, dust-free room.
The compact, easily exchangeable control box is available in 2 versions:
MS 15-5
standard version including the control functions: wire feed rate,
wire burnback time, wire creep-in, two-cycle/four-cycle switch, wire feed guide.
Regulation of weld grade and choke
A coarse-adjustment switch (MIG 326 / 406 / 506) and a 12-grade fine-adjustment switch allow 24-grade
regulation of welding intensity.
Two selectable choke versions to match the applied welding voltage and wire diameter.
Wire feed system with four-roller drive
Cooling of power source by fan
The gas-cooled model of the MIG 296/326 provides thermostatically controlled cooling. The power source is
cooled by a low-noise fan. In case of thermal overload, a built-in thermoswitch cuts off the welding-current.
When the welding unit is started cold, the fan is not in operation.
Only when the power source gets heated by the welding operation does the thermostat switch on the fan, and
off again when the power source has cooled down.
Only in the MIG 406W/506W the fan operates always for the water cooling system.
Central connecting socket
The master connecting socket allows rapid coupling and decoupling of the torch.
Welding under increased electrical hazard
The unit may be used for welding operations under increased electrical hazard according to European Standard
EN 60 974-1.
Easy to service
thanks to accessible and maintenance-friendly arrangement. With a few deft movements, the complete control
box can be exchanged.
Circulating water-cooling for cooling the torch (Option)
Water-cooled torch:
The torch is cooled by a bulit-in low-noise, pump operated, water-cooling system. The water tank should be kept
almost full. After changing the torch or hose sections, check water level in the tank.
Low-water switch:
If the cooling water pressure drops, a manometric switch cuts off the mains contactor. Welding wire will still
being conveyed, but there is no current flow.
The unit will be operable again when normal working pressure has been restored in the cooling system.
