New Tweco Numbered Series MIG Gun Offers Superior Toughness

ST. LOUIS, —Tweco, a Victor Technologies brand, today launched the Tweco Classic Number 4 MIG gun, an enhancement of the legendary Tweco Number 4, one of the most popular guns in the world and referred to as, “the MIG Gun that Built America.”

Enhancements to the Tweco Classic include higher impact resistant materials, an interlocking handle design for superior toughness, an angled trigger for a more comfortable pull and refined, modernized lines. The Tweco Classic 4 is an air-cooled MIG gun with a rating of 400 amps at 60% duty cycle.

“I like the Tweco Classic handle because it's flatter,” says Jeremy Holloway, a welder/fitter with Bellingham Metal Works, Bellingham, Mass. “Skinny handles you have to squeeze a lot more - it puts a lot of stress on your hand. This gun is nice because you barely have to move your finger to pull the trigger.”

BMW Project Manager Robert Stow, Jr. also likes the gun’s heavy-duty construction. “The Tweco guns are excellent for our shop,” says Stow (view video). “Our guys are pretty rough on the equipment, and Tweco guns stand up. They’re very durable. I’m only going to make money in this company if we’re producing parts.”

New Series

The Tweco Classic 4 is the first in a new series of air-cooled guns that will roll out later in 2013. The other products are: the Tweco Classic 2 (rated at 200 amps @ 60% duty cycle), the Tweco Classic 3 (300 amps @ 60% duty cycle), the Tweco Classic 5 (500 amps @ 60% duty cycle) and the Tweco Classic 6 (600 amps @ 60% duty cycle).

“The Tweco Classic Series will carry on the tradition of the Tweco No. Series platform, which has stood the test of time since its introduction at the AWS Welding Show in 1969,” says David Wilton, Vice President, Brand Management - Welding Products, Victor Technologies. “Millions of welders will be familiar with the way the paddle-style handle of a Tweco Classic gun fits into their hand and enables them to manipulate the arc. With these upgrades, they’ll be able to enjoy its heavy-duty, industrial-grade performance for years to come.”

One of those millions of welders is Abdul Kahn, a South African who immigrated to America in 1969 and became a classic success story by learning to MIG weld with a Tweco gun in his hand. When Kahn saw the pre-production model of the Tweco Classic 4 at FABTECH 2012, he took a few minutes to share his story (view video).
