Hobart H100S4 MIG gun for light fabrication

The Hobart 284546 is an air-cooled MIG gun rated at 100 A with a 100 percent duty cycle. It accepts solid or flux-cored wire from .030 to .035 in. The 10 ft cable and rear connection suit Hobart-compatible feeders in automotive and general workshop use.

Rotatable neck and standard trigger change daily

A 60-degree rotatable neck tube lets the operator adjust the angle without tools. The straight handle and standard trigger keep the grip familiar for repetitive welds. These features reduce wrist strain during long passes on thin sheet metal.

Air-cooled construction

The air-cooled design avoids water lines, so there are no leaks or coolant changes. M-Series contact tips are widely available and swap quickly. The gun handles both flux-cored and MIG processes without hardware changes.

Questions about this item

How often will the M-Series contact tip need replacing when running .035 wire at 100 A?

The M-Series tip is a wear part; replacement frequency depends on wire feed speed, duty cycle and spatter levels, so inspect it each spool change and swap when the bore wears oversize.

What stops the 100 A air-cooled gun from running continuously at full output?

The 100 % duty cycle rating means the gun is designed for continuous 100 A operation without a thermal limit, provided ambient temperature and cable layout allow adequate air cooling.

How hot does the handle get during an all-day 100 A production shift?

The air-cooled design dissipates heat through the 10 ft cable and neck tube; the straight handle stays warm but remains within safe touch limits at the rated 100 % duty cycle.
