DESCRIPTION
The MP140 consists of a combina-
tion MIG welding power source and
wire feed unit, a MIG torch with 10
foot cable, a ten foot work (ground)
cable with ground clamp, a fifteen
foot power input cable, a gas
regulator/flowmeter, a torch ac-
cessory kit, and a built-in cylin-
der rack and industrial wheel kit.
Welder controls are simple and
clearly marked. The output voltage
is controlled by a six position tap
switch, providing six voltage se-
lections. Voltages can be moni-
tored by the voltmeter on the
control panel. Wire feed speed is
controlled by the wire speed poten-
tiometer.
An OPTIONAL SPOT/STITCH WELD
(SSTP-2)control module with ad-
justable timer circuit provides
Consumable MIG Spot Welding or
Stitch Welding capabilities of
light gauge steel.
