Operation

Description

The Forney 190 MIG welder is designed for use on jobs involving maintenance and fabrication. It is
ideal for applications such as farming, automotive, and repairs. This transformer-based machine is
powered from 230V current and produces up to 190A output. The acceptable wire diameters for use
on this machine include .024", .030", and .035". The spool sizes compatible with this machine are
4" and 8" and should be loading clockwise, so the wire feeds from the top into the wire feeing system.
This machine can weld materials up to 1/4" in thickness.
Units may be used with the standard torch.

Welder Controls

1. Main ON/OFF switch and welding voltage adjustment
2. Wire feed adjustment knob:
To increase the wire speed, turn the potentiometer clockwise; to decrease the wire speed, turn
it counter-clockwise. The same procedure decreases the values on the welding parameters. Turn
knob slowly.
3. Ground Clamp
4. MIG Torch/Gun

Thermal Overload Protection

WARNING: If the duty cycle of the welder is exceeded, a thermostat will automatically cut
the power to prevent the machine from overheating. If this should happen do not unplug the
machine while it cools down. The thermostat will automatically reset itself and you can continue
welding. The thermostat is a protective safety device and no harm will normally be done to the
welder unless it is frequently over-loaded, in which case it may eventually become damaged.
