Hobart Arc Welding Machine LX 235 AC

- Repair or replace cracked cables

Touching live electrical parts can cause fatal shocks or severe burns.; The electrode and work circuit is electrically live whenever the output is on.; The input power circuit and machine internal circuits are also live when power is on.; In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live.; Incorrectly installed or improperly grounded equipment is a hazard.

- Do not touch live electrical parts.

- Wear dry, hole-free insulating gloves and body protection.

- Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground.

- Do not use AC output in damp areas, if movement is confined, or if there is a danger of falling.

Turn Off welding power source and disconnect input power.

4. Transformer And Shunt (Located Inside Unit)

- Insert crank handle onto shunt shaft protruding through front panel and turn crank handle to adjust shunt to the proper vale of "X", depending on model (see detail of transformer and shunt.

Turn Off welding power source and disconnect input power.

Note: Do not grease screw threads on shunt block.

- Apply light coating of high-temperature grease to shaded areas of both shunt blocks. Turn amperage control handle to spread grease evenly.

- If shunt block vibrates and becomes noisy, tighten adjustment screws 1/4 turn.; - Install wrapper, turn On unit, and check for shunt noise. Repeat procedure until noise stops. Do not overtighten. Call your nearest Factory Authorized Service Agent if noise continues.

Note: Install wrapper before turning On power.
