Frequently Asked Questions - GIS 140 Güde

What type of welding does this device support?

This device supports MMA welding (stick welding). It is designed for the thermal assembly of ferrous metals by melting edges and adding filler material.

How to adjust the welding current?

The welding current is adjusted using a rotary knob on the front panel. The adjustment range is 20 A to 140 A.

What is the maximum thickness of metal that can be welded?

The maximum weldable metal thickness is approximately 7 mm in a single pass, with a suitable electrode.

Which electrodes to use with the GIS 140?

Use electrodes with a diameter between 1.0 and 4.0 mm depending on the metal thickness and the chosen current.

What safety precautions to take before use?

Wear a welding helmet, protective gloves, an apron and safety shoes. Make sure the device is plugged into an outlet with a 30 mA differential circuit breaker.

What to do if the electric arc goes out during welding?

Check the contact of the ground clamp and the electrode. Clean the welding area to remove paint, rust or dirt.

Why does the device stop after prolonged use?

This is normal: the welding machine is equipped with a thermal protection that triggers in case of overheating. Let it cool down for a few minutes before resuming.

How to clean and maintain the device?

Always unplug the device before cleaning. Use a damp cloth (no solvents) and a soft brush for the ventilation openings. Lubricate moving metal parts with oil.

What is the required input power?

The device requires a power supply of 230 V ~ 50-60 Hz and a 16 A time-delay fuse. Use an extension cord with a minimum cross-section of 1.5 mm² and a maximum length of 5 m.

Where to find spare parts and after-sales service?

Visit the website www.guede.com (Service section) or contact customer service. Have the serial number, order number and year of manufacture (on the nameplate) ready.

Safety instructions

WARNING! Electric shock! There is a risk of an injury caused by electric shock!

Operation is only allowed with a safety switch against stray current (RCD max. stray current of 30mA ).

IP21 protection degree of the welder. The welder must not be exposed to rain and moisture when being operated or stored.

Check the voltage. Technical data given on the type label must correspond with electric network voltage.

Insert the plug of the electrical cable in a socket of suitable shape, voltage and frequency complying with current regulations.

Use extension cables with a maximum length of 5 meters and with a cable cross-section of not less than 1.5mm² Use of extension cables of different length and cross-section and also of adapters and multiple sockets should be avoided.

Check the cable and/or socket for damages before the appliance putting into operation.

Defective cable or plug may cause electric shock. Do not pull the service cable to pull the plug out of

socket.

Do not expose yourself or other persons without protection to electric arc or hot metal. Spraying welding pearls may cause burns.

A suitable welding shield, protective clothes and protective gloves to be worn at all times.

Long-term inhalation of welding gases may be harmful to your health.

Work with an exhaust system or in well ventilated spaces. Avoid direct inhalation of gases.

Contact with the hose bundle nozzle and the material being processed may cause burns. Special welding gloves to be worn at all times.

Let the hose bundle nozzle and the material being processed cool down after being operated.

Long-term working with the appliance may damage hearing. Hearing protection to be used at all times.

Make sure the welding smoke is exhausted or the place of welding ventilated well.

Hot slag and sparks may cause fire or explosion. Never use the appliance in a flammable environment.

Wood, sawdust, "varnishes", petrol, kerosine, natural gas, acetylene, propane and similar flammable materials must be removed from the place of work and the surrounding area or protected against sparks flying away.

To extinguish fire, a suitable fire extinguisher must be made ready nearby.

No welding or cutting on closed vessels and pipes.

No welding or cutting on vessels and pipes if they are open, containing materials able to explode due to heat or moisture or able to cause other dangerous reactions.

Never use the welder to defrost frozen pipes.

Before putting into operation, a qualified electrician must check whether electric safety measures required are in place. Any national regulations in this regard must be complied with.

Protect the circuit with slow-acting fuses of an appropriate size and a mains breaker switch.

Class A (IEC 60974-10):

If you intend to use the apparatus in residential surroundings supplied by the low voltage mains supply, an electromagnetic filter may be required to suppress electrical disturbance to a level where they will no longer be a nuisance to the user.

The apparatus may be used in industrial or other areas where power is not supplied by municipal LV mains.

Class A apparatus are not intended for use in resi

dental areas where power is supplied via municipal LV mains, since unfavourable power conditions may cause interference.
