Developed using customer feedback, the GXe MIG/MAG welding torches feature a structure that enhances durability, improves welding characteristics, and ensures optimal balance for greater control and comfort, even in the most challenging environment. A 6-month warranty backs ins performance, underscoring its reliability and cost-efficient.
Series 5 with Euro Connector and hose package.
Answers for buyers of air-cooled and water-cooled MIG/MAG torches with a Euro connector and a hose package: choosing, coolant, set-up and care.
Air-cooled torches use the surrounding air and the shielding gas to carry heat away. They need no cooler or extra hoses, so they are simpler to set up, maintain and move, which suits field work. Their cables are heavier and less flexible at higher currents.Water-cooled torches circulate coolant through a cooler, which gives a lighter, more flexible cable for the same current and is the usual choice for sustained high-current work, though it adds equipment and upkeep. Decide on your typical current and how long you weld at it, and check the rating at your duty cycle.
Use a coolant made for welding torches and follow the cooler maker's instructions. Many makers advise against plain tap water: its conductivity can cause electrochemical corrosion that damages the torch and other equipment, and minerals can leave scale in the hoses. Check your cooler and torch manuals before using anything else.Check the coolant regularly and replace it if it is contaminated, because particles can clog the cooling channels. Some makers also give a conductivity limit for the coolant, so check the manuals for how often to test it and what to replace it with.
Check that the torch is securely connected, that the hose package and torch neck show no damage, bends or impact marks, and that the coolant level is adequate. Make sure the liner suits the wire material and diameter you are about to use.Allow time for the coolant to fill the system before you weld at high current, and look for leaks at the hose connections. If the cooler gives a flow or temperature warning, stop welding and find the cause before carrying on.
Lay it out loosely and avoid sharp bends, crushing and pulling. Tight bends raise friction on the wire and wear the liner faster, and a crushed or kinked hose can restrict gas flow or coolant flow.Choose a length that suits the job, because a package that is too short is strained and one that is much too long adds wear and drag. Do not run trolleys or vehicles over it, and do not use it to pull the torch around. Check it for cuts and kinks as part of your pre-use inspection.
At high current the front end of the torch runs hotter and sees more spatter and heat, so the nozzle, contact tip and diffuser wear sooner. An overloaded torch will overheat the nozzle in particular, so use a torch whose rating is suited to your current and duty cycle.Keep the nozzle clear of spatter, keep every front-end part tight, and replace worn parts promptly. For abrasive wires or heavy loads, ask your supplier or the maker about harder contact tip materials.
Look at the tip rather than counting hours. Replace it when the bore has worn oval, is clogged, or the tip is discoloured from overheating. A worn tip often shows up as a wandering arc, extra spatter or burnback.Fit the correct bore for the wire diameter, tighten it firmly with a suitable tool so it seats flat on the holder, and blow out the wire path with compressed air when you change it. There is no need to change a tip that is still in good condition just because it has been in use for a while.
