Precision Arc Performance:
• Patented Micro-Start II™ Technology delivers extremely stable low
amperage starting, welding and cratering for both AC and DC
welding.
• Selectable welding modes such as high frequency, scratch start, and
Touch Start TIG
®
.
• High duty cycles–375 amps at 40% duty cycle.
• Widest welding range in its class 2-420 amps for both AC and DC.
• Advanced Control Panel. TIG pulser allows you to control heat input
for any weld.
• Standard power factor correction capacitors lower input currents
when welding at higher output.
• Excellent stick welder–even with Fleetweld
®
5P (E6010) with new
Automatic Hot Start™ and Auto Adaptive Arc Force™ controls.
Simple Controls – Easy to Use:
• Redesigned controls are simple and well-spaced for effortless setting
changes.
• Hidden menu button features 7 programmable parameters without
cluttering the control panel.
• New and Improved AC Auto Balance
®
has been readjusted to have
more penetration and improved bead appearance.
• Spot On Timer provides adjustable arc for consistent spot welds.

applications.
• Built-in storage compartment for torch consumables.
• Water-cooled torch connections with no adapters required–side
mounted, out of the way, and well protected.
• Neat/organized cable management with integrated torch holster.
Superb Quality:
• Fan-As-Needed™ (F.A.N.) prevents overheating. F.A.N. reduces power
consumption noise, motor wear and dust in the machine.
• CSA C/US certified.
