Welding Guns/Torches
A welding gun directs the wire to the joint, transfers the welding current to the wire and provides the gas for shielding the arc and weldpool. For light duty work, air-cooled guns rely on the shielding gas passing through the body to cool the nozzle and have a limited current-carrying capacity. Water-cooled guns are preferred for high current levels, especially at high duty cycles. In electric welding, the torch conducts electric current to the electrode and carries the shielding gas to the arc zone of the welding arc. In gas welding, the torch adjusts the mixture of gases and guides the welding flame. Torches may be moved along the edges being welded by hand or automatically.
How to Prevent Common Causes of Poor Weld Wire Feeding
Identifying the culprit can be complicated. Luckily, premature consumables failure, burnbacks, and bird-nesting are often easily resolved – so you’ll soon be welding again.

Every extra part wrung from the same piece of raw and remnant material is money in your pocket. Here’s how to significantly increase earnings.
Take a close look at the impact of welding consumables on your overall operation, not just the purchase price. Here are some key tips on how to properly select, install and maintain consumables and troubleshoot problems when they arise – and, better yet, how to prevent them in the first place.
Preventive maintenance on peripherals such as reamers with anti-spatter sprayers and wire cutters is part of the routine care of a weld cell. The time and cost to maintain them properly is small compared to the improvements they provide to the bottom line through higher weld quality, minimal rework and improved productivity.
The problem may be as simple as a loose contact tip or something more complex, like incorrect TCP. Understanding the steps for proper troubleshooting helps narrow down potential causes, prevents replacement of components that don’t need replacing, and quickly gets you back to producing quality parts.
Three Tweco-brand welding guns from ESAB offer comfortable high-performance operation when working with large-diameter cored, solid, and aluminum wire and long-reach applications.
CenterLine introduces two SoftMount inverted-nut gun configurations for a high-speed fastener welding system that streamlines the process from operator load to finished part, providing higher throughput than standard welding solutions.
Fronius’ welding torches for manual Tungsten Inert Gas welding (TIG) can be customized to suit the welder’s personal preferences as well as the welding task at hand. Their modular design offers a range of sustainable and cost-effective options.
