Gun holders torch support GH 20.

A series of gun holders for increasing the operating life of welding guns. They can be mounted on a welding machine, transport unit, or welding table. Kemppi has launched a series of gun holders to increase the durability of welding guns. The holders are primarily meant to be mounted on the welding machines, but depending on the model, they can also be mounted on transport units or welding tables. GH gun holders can be mounted to all Kemppi MIG/TIG welding machines.

Kemppi Fastmig M Series Parts FAQs

Spares for a modular MIG welder and its wire feeder and water cooler, and how to match and fit them safely.

Is it safe to open a MIG power source to fit a circuit card or capacitor card?

Only a competent person should do it. Welding power sources contain mains voltage and, in inverter designs, capacitors that can hold a charge after the machine is switched off. Switch off, disconnect the mains supply and follow the maker's service instructions for waiting and discharging before touching any internal part.

Use a qualified electrician for electrical repairs and testing, and never use damaged or faulty equipment. The HSE has also reported a fatal shock where welding equipment was not switched off. The wait time and discharge method depend on the machine, so check the service manual.

How can I tell if a gas solenoid valve is the cause of a shielding gas problem?

Check the simple things first. Plugged gas ports, a ruptured hose, incorrect flow or a clogged nozzle can all let air into the weld and cause porosity, according to a welding consumables maker's troubleshooting guide. A faulty solenoid is another listed cause.

Signs of a failing valve include no gas when the trigger is pulled, gas that will not stop or flow that is weak or irregular. A common check is to confirm gas reaches the torch end, then work back through the hose and fittings to the valve. If the valve is suspect, have it tested and replaced by a competent person, matching the coil voltage and fittings of the original.

What wears out in the wire feeder, and what should I check before replacing electronics?

Mechanical parts wear far more often than electronics. Worn, wrong-size or badly tensioned drive rolls, a worn or kinked liner and a worn contact tip are frequent causes of erratic feeding, and welding consumable makers advise checking the rolls and tip before the liner, which is more work to replace.

If the rolls do not turn at all when the trigger is pulled, look for a fault in the connections, trigger or control leads. Too much roll tension can deform the wire and damage the liner and tip. Only after the mechanical side is ruled out is a feeder card or motor likely to be the cause.

What do I need to know about water cooler parts and coolant?

A water cooler circulates coolant through the torch and hoses, so its pump, tank, filter and hoses all need to be sound. Use the coolant type the maker specifies and change it on the maker's schedule. Many makers advise against plain tap water because minerals can scale up and restrict flow, but check your manual.

Check regularly for leaks. A trade guide to welding equipment says leaks at the torch need immediate attention because of the risk of electric shock. Switch off and isolate the machine before working on the cooler, and use a competent person for pump or electrical repairs.
