Hobart Welding Products has introduced the Trek 180, a self-contained, battery-powered MIG welding package for true off-the-grid welding.

The portable 52lb Trek delivers heavy-duty weld power to fabricate or repair 24SWG up to 1/4in (6.3mm) mild steel in a single pass.

Two internal batteries enable the Trek to achieve a 100 per cent charge in 90min or a 20min, 80 per cent quick charge from a standard 115V wall outlet or within a vehicle, using an automotive power inverter.

The Trek 180 is designed to meet the demands of MRO professionals who require arc performance in a portable package.

It is designed to operate while plugged in or completely cordless and its detachable power cord plugs into standard 115V receptacles.

The Trek 180 can be charged inside a vehicle with an automotive power inverter (400W continuous).

While charging, Hobart’s Autopower technology automatically scans the available input charging power as not to over stress low-capacity devices such as automotive inverters.

Two internal, high-performance, sealed lead-acid batteries provide the energy storage needed for welding in remote applications.

The batteries feature Thin Plate Pure Lead (TPPL) technology, allowing the Trek to achieve a 20min, 80 per cent quick charge or full charge in approximately 90min.

When fully charged, the unit delivers approximately 100in of continuous weld bead using 0.030in (0.8mm) diameter flux-cored wire on 1/8in (3.2mm) mild steel.

Unlike other battery welders, battery power is monitored continuously to provide consistent welding voltage, regardless of the charge level.

The Trek’s low-battery shutdown feature disables the welder when the battery runs low, protecting the life of the battery and quality of weld output.

On battery power alone, the Trek 180 offers a rated output of 120A, 17V DC at 20 per cent duty cycle.

When plugged into standard 115V power, the unit is capable of delivering 180A.

The Trek’s 12A power draw allows good performance when using cheap or low-quality extension cords.

A removable storage bag secures all the Trek’s cables, MIG gun, work clamp and removable power cord with additional room for extra wire, contact tips and welding gloves.

The bag can be detached, allowing the unit to slide under a seat of a truck, or strapped down.

Inverter-based technology enables Hobart’s Trek 180 to control arc characteristics thousands of times faster than conventional transformer technology, according to the company.

As a result, the unit provides positive arc starts without popping and minimal spatter while welding.

The Trek 180 features a durable built-in wire feeder with a quick-release tension lever.

Accepting 4in spools of 0.023-0.035in (0.6-0.9mm) wire, its cast aluminum dual-groove drive rolls can be configured for a smooth or knurled feeding performance.

Its infinite voltage and wire feed control provides a broader operating window for each wire, allowing operators to quickly fine-tune the welding arc for their desired output on different materials and thicknesses.

LED diagnostic lights on the front of the unit provide quick information on temperature, charging and battery status.

Trek 180’s case is made from impact-resistant plastic.

Hobart engineers comprehensively tested the trek for reliability in extreme environments and situations.
