tools-yeildWhen the GMA welding arc becomes erratic, should the operator adjust the power source? Not necessarily. If the voltage and wire feed speed values currently used previously worked well, and if the correct shielding gas and flow rates have been selected, worn components are likely at the root of the problem.

Liners, tips and other gun components need routine inspection to ensure consistent GMAW performance. Good maintenance also prevents rework, eliminates unplanned downtime and maximizes gun life. The following maintenance practices apply to most brands of guns. Before working on a gun, review the operator’s manual and follow appropriate safety precautions to prevent burns or electric shock.

Cleaning Liners
Erratic GMA performance occurs when excessive friction causes the electrode stick or slip. When wire feed speed slows, yet voltage remains constant, the electrode will melt back from the weld puddle more quickly and produce an erratic arc. One of the most common culprits is a gun liner that has become clogged with wire shavings and other particulates.

Operators everywhere should get in the habit of blowing out the liner with compressed air when installing a new spool of wire. For GMAW systems with a high arc-on time, operators might consider blowing out the liner more frequently (experience will dictate the need).

How rapidly a liner clogs varies greatly. Over-tensioning the drive rolls on flux cored electrodes can clog a liner quickly. Electrodes exposed to the elements, especially humidity and salt air, can quickly clog a liner, as can a poor quality electrode. Different electrode manufacturers use different drawing compounds and substances to coat and finish the electrode. As a result, some clog liners faster than others — sometimes in half a spool or less. To keep liners cleaner longer, consider installing cleaning pads during the next scheduled maintenance. Use good cleaning pads and secure them properly, otherwise bits of the pad may end up clogging the liner.

For a clearer indication of particulate volume inside the gun liner, place a sheet of paper or cardboard under the gun to provide better contrast. If the arc is erratic and blowing out the liner reveals only small amounts of particulate, the liner is worn and should be replaced. For example, in the Tweco test lab, using a leading brand of 1/16-in. diameter ER70 S-6 electrode, applying these guidelines, we most frequently replace the liner after two 60-lb. spools.

Replacing Liners
blowing_out_linerTo replace a liner, remove the old liner, lay the new liner next to it on the floor and cut the new liner to the exact same length. A liner that is too short can interfere with feeding performance and lead to an erratic arc. Further, if a void exists between the liner and the diffuser, it could create a spot that traps the wire and leads to a bird nest.

When trimming the new liner, use sharp, premium quality side cutters. To produce a clean cut, place the cup side of cutters against the liner and orient the cutters so that they cut against the curl of the liner. Cutting with the curl tends to produce a burr on the inside edge of the liner, where it could drag against the wire. Never use dull cutters or whelpers to trim a liner. Rather than cleanly cut through the tough piano wire used for liners, they will most likely deform the liner and/or spread out the coils.

Never use a cutting disc (e.g., RotoZip® or similar tool), as it can leave a sharp edge that drags against the electrode and creates shavings. Should the cut liner have a burr, use a hand file to remove it. Otherwise, discard it and try again.

trim_linerAs with any mechanical system, don’t use excessive force when installing a new liner. If the liner hangs up, twist it in a counter clockwise direction so as not to uncoil the liner. If the liner doesn’t fit, the liner could be too long (in which case, trim it) or it could be bent. If the liner is bent, discard it, as a bent liner can promote erratic feeding.

Some gun models use small screws to keep the liner from twisting. Do not remove or discard those screws. First, if the liner twists independently from the gun cable, it can increase or decrease the length of liner relative to the length of the gun cable. Second, an absent screw may permit shielding gas to escape through the hole instead of coming out the diffuser, which may lead to insufficient gas coverage or excessive gas flow to compensate for lost gas.
consumables_drawerSpatter and Tips, Nozzles And Diffusers
The GMA process, especially short circuit transfer, inherently produces spatter.

A percentage of operators inherently feel compelled to knock spatter off by banging the gun on the welding table or work piece. Banging the gun doesn’t do much to remove spatter, but it’s a great way to loosen component connections at the front of the gun. Don’t bang the gun!

With Mike Balboni putting his 3-in-1 welders to the test on a daily basis, Victor Technologies asked him to test

the new Tweco Fusion series of light-duty MIG guns. He immediately recognized some of the gun’s unique features

Fusion Gun

 

“Simplicity of design. That’s what’s going to set these guys

apart from everybody else,” he says (view video).

 

Northeast Welding 3These guns now come standard on all 3-in-1 welders, and they feature Tweco’s new Velocity MIG consumables platform.

The non-threaded, “drop-in” style contact tip eliminates the need to use vice-grips, welpers or other tools to remove the tip,

even if the wire burns back and fuses inside the tip. The Velocity™ consumables design integrates the gas diffuser into the

conductor tube. This creates an improved all-copper conductor

path that provides better electrical conductivity and transfers heat

more efficiently away from the tip. As a result, the arc becomes

more stable and predictable.

The design also eliminates the insulator found on other MIG guns. Balboni says that insulators often become loose and worn, causing the nozzle to fall off in the middle of a job. The Tweco Fusion gun has eliminated that weak point, “so these guns will never hang on the wall. They will always be in operation.”

Co-branding strategy reinforces Victor® as leading the advancement of cutting and gas control solutions.

Victor Technologies today announced that it has realigned its brand portfolio to position Victor® as the lead brand for cutting and gas control products. “With all cutting processes unified under the Victor brand — and a combined 200+ years of technology advancements — we offer the most advanced array of cutting solutions in the market,” says Martin Quinn, CEO, Victor Technologies.

The company’s line-up now consists of:

  •  Victor Thermal Dynamics®, which encompasses manual and automated plasma cutting systems.
  •  Victor TurboTorch®, which includes air-fuel products for brazing and soldering.
  •  Victor Arcair®, which represents manual and automated gouging systems.
  •  Oxy-fuel cutting and gas control equipment remains branded as Victor.

The Victor announcement is part of the company’s strategy to leverage the strength of its diverse brand portfolio and enhance its position as an innovative provider of cutting, welding and gas control solutions. Visitors at the industry’s premier event, FABTECH (Las Vegas, November 12 – 14), saw examples of the new branding that included updated brand marks and new product packaging.

Victor Technologies demonstrated their commitment to design and manufacture innovative new products with the showcasing of the Victor Thermal Dynamics iCNC® XT Controller, added through the acquisition of Robotronic Oy and ProMotion Controls earlier this year. The iCNC XT brings intelligence to the cutting table and enhances Victor Thermal Dynamics position as a comprehensive solutions provider in automated plasma cutting. The “intelligence” inside the iCNC XT enables the end user to optimize cut quality and speed at a lower cost per cut, regardless of their plasma cutting and programming experience.
