Multiprocess Welding
Power Source
Issued October 2007 • Index No. DC/18.83
Lightweight, aerospace-grade aluminum case
offers protection with the benefit of reduced weight.
Power Management Technology allows for any input voltage hook-up (208 – 575 V) with no manual linking required, providing convenience in any job setting. Ideal solution for dirty or unreliable input power.
Lift-Arc
allows TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten.
Adaptive Hot Start
increases the output amperage at the start of a weld if necessary, eliminating electrode sticking.
Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance, and outstanding MIG weld performance.
Fan-On-Demand
cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.
The Power of Blue®.
Wind Tunnel Technology™protects electrical
components and PC boards from contamination.

XMT 350 VS
Line voltage compensation keeps welding output
constant even if input power varies by +/-10%. XMT 350 models further expand line voltage compensation on 460 VAC to an amazing +37%, -59%.
Process selector switch reduces the number of control setup combi nations without reducing any features.
Large, dual digital meters are easy to view and are presettable to ease setting weld output.
The XMT 350 Series is packed with features to meet the most demanding welding needs.

Additional Features
Low OCV Stick — A built-in, selectable feature, that reduces the Stick mode open-circuit voltage (OCV) to nearly 15 volts when the welding power source is not in use. Eliminates the need for add-on voltage reducers.
Note: VS model is available only with Tweco-style weld cable disconnects. Tweco cable connectors are not supplied with the unit and must be ordered separately.
Optional 115 VAC auxiliary power is not available on VS model.
Pulsed MIG (GMAW-P) capability is not available on VS model.
Additional Features
Auto Remote Sense™enables unit to
automatically use remote control if connected to remote control receptacle.
Low OCV Stick — A built-in, selectable feature, that reduces the Stick mode open-circuit voltage (OCV) to nearly 15 volts when the welding power source is not in use. Eliminates the need for add-on voltage reducers.
Dinse International-style weld disconnects
provide high-quality weld cable connections. Dinse and Tweco connectors are available. When Dinse connectors are specified, two connectors are supplied with the unit.
Optional 115 VAC auxiliary power provides 10 amps of circuit-breaker-protected power for water circulators, etc.
Pulsed MIG (GMAW-P) capabilities with optional Optima
control reduces spatter and distortion, allows better out-of-position puddle control, and provides potential reduction of fume particle emission.

Optional 115 VAC auxiliary power provides 10 amps of circuit-breaker-protected power for water circulators, etc.
SharpArc controls welding arc cone width in Pulsed MIG (GMAW-P) welding mode.
If a gas is used other than what is listed on the Pulsed MIG welding program chart (below left), the SharpArc
can be adjusted to help customize your arc to the gas being used.
Lower SharpArc
settings widen the arc cone, increase puddle fluidity and flattens the weld bead.
MPa: M (MIG), P (Pulse), a (Advanced Arc Control). Advanced arc control
enables an improved pulse welding arc. The operator has more control over puddle and bead characteristics using SharpArc
. In addition, the unit provides a more robust and stable arc at very low arc length, reducing heat input, and providing the ability to weld on a wider range of material thickness.
The XMT 350 MPa expands the process capability of an XMT 350 with built-in Pulse MIG operation. See the table below for the wide range of Pulsed MIG (GMAW-P) welding applications the XMT 350 MPa can handle.
The simple, powerful XMT 350 MPa can handle almost any portable welding application.
