Fan-On-Demand

™

which operates

only when needed. This feature

reduces noise, energy use and the

amount of contaminants pulled

through machine.

Lift-Arc

™

allows TIG starting without

the use of high-frequency. Starts the

arc without contaminating the weld

with tungsten.

Process selector switch automatically

sets contactor requirements, elim -

inating confusion caused by several

switch combinations and making this

machine very “operator-friendly.”

Enhanced environmental protection.

All critical components housed in

protective enclosures.

Help codes help troubleshoot and

service power source. Help codes are

displayed on the volt/amp meters.

Reduces the time needed to get the

machine back into service.

DC multiprocess capability

provides versatility and

outstanding arc performance

in CV (MIG) and CC (Stick,

TIG, CAC-A).

Inductance/DIG control with

presettable digital display to

optimize MIG/Stick

performance.

Internal digital voltage control

(DVC) enables operator to

preset weld voltage in the

CV mode prior to welding.

Line voltage compensation

ensures consistent weld

performance by keeping

output power constant even if

primary input power varies by

±10 percent.

Power efficient for exceptional

value and return on your

investment.

115 VAC duplex receptacle

provides 15 amps of auxiliary

power.

Thermal overload protection

helps prevent machine damage

if the duty cycle is exceeded or

airflow is blocked.
