Patented Micro-Start™ II Technology delivers extremely stable low amperage starting, welding and cratering for AC and DC welding. FREE TIG Pulser – Optimal heat input control results in reduced warping and burnthrough on thin materials and improved appearance. Excellent Stick Welder – even with Fleetweld® 5P (E6010). AC Auto Balance® automatically sets the optimal cleaning vs. penetration levels for great looking aluminum welds. 115 volt auxiliary power receptacles with 20 amp service reliably powers water coolers or other tools (208/230V model only, all other models 6 amps). Standard torch parts storage compartment and cable hanger keeps you organized. 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.

A CLOSER LOOK “Set It/See It” Pulse Control — Results Make attractive and consistent welds! Better control of heat input in the weld, resulting in: What Is It? • Reduced warping and burnthrough on thin materials. Pulse welding systems vary weld current between peak (high heat) and background current (low heat) levels. Adjusting the pulse frequency controls the level of heat input applied to the weld relative to the weld travel speed. For the Precision TIG® 225, pulse frequency can be varied from 0.1 to 20 pulses per second. • Smaller heat-affected zone. • Smaller bead profile without compromising...
