OBLIGATIONS TO THE CUSTOMER :

OBLIGATIONS TO THE CUSTOMER Advanced equipment assuring OEM quality repairs The Collision Repair Industry has an obligation to correctly repair the customer's vehicle. Collision Repairs must be performed using: Recommended or tested procedures from vehicle makers, I-CAR and other research and testing organizations

HIGH STRENGTH STEELS:

HIGH STRENGTH STEELS With the advent of high-strength steels and coated metals used in vehicles MIG (Metal Inert Gas) welding was the only repair method available.

HIGH STRENGHT STEELS:

HIGH STRENGHT STEELS The downside is MIG welding creates: excessive heat that affects the properties of the metal surrounding the area and also requires additional labor to drill and perform the weld, then grind and prep the weld for paint

OEM WELDING:

OEM WELDING Squeeze-type resistance spot welding, (STRSW) is the main welding method performed by robots by the vehicle makers. To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

(STRSW Squeeze Type Resistance Spot Welding):

(STRSW Squeeze Type Resistance Spot Welding) Significant advances in engineering of STRSW and technology (structural adhesives) have now enabled repair facilities to duplicate the OEM weld. Not only performs the same but significantly increases productivity and efficiency of the repair process and maintains the integrity of the metal.

STRSW ADVANTAGES

ADVANTAGES TO SPOT WELDING:

ADVANTAGES TO SPOT WELDING Since the process is the same, collision repair spot welds have an OEM weld appearance and there is no need to dress the weld. Additionally, removing a panel that has been replaced using spot welds is similar to removing the original panel. To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

The Three stages of STRSW:

The Three stages of STRSW Squeeze Time Occurs when the electrode tips close against the panels to be welded. Current Flow Creates the weld, last for only a fraction of a second. Hold Time Allows the weld to solidify by holding for a couple of seconds after the current is turned off.

Machine Settings:

Machine Settings Current Provides the heat to the weld, the thicker the metal, the higher the current required Weld Time Adjust the time that current passes through the joint, must be balanced with current Pressure The electrode force, measured at the electrodes including: Squeeze time, before the current is on Active force, when the current is on Holding force, when the current is off To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

STRSW machine are either liquid-cooled or air-cooled :

STRSW machine are either liquid-cooled or air-cooled Liquid-cooled systems use a 50/50 mixture of conventional coolant and water More efficient than air-cooled machines because the electrode tips do not get hot as quickly Air-cooled systems Use the same compressed air source as the inlet pressure for the electrode arms to constantly pump air into the electrode tip holders and connecting cables

TWO COMMON SPOT WELDING ARMS:

TWO COMMON SPOT WELDING ARMS G-CLAMP piston type uses a stationary arm and piston arm that moves towards the stationary arm. With this clamp there is less reduction in tip pressure when longer arms are used. To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

C STYLE WELDING CLAMPS:

C STYLE WELDING CLAMPS A wider variety of arms allow access to more of the car body, but When the length of the arm is doubled, the force at the electrode tip is reduced by 1/3 or more. To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

What will a STRSW do for Me?:

What will a STRSW do for Me? Provide your technicians with equipment that will increase productivity Industry tests under actual shop conditions show that resistance spot welding is on average 45% faster than MIG plug welding and as strong or stronger To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

What will a STRSW do for Me?:

What will a STRSW do for Me? Spot welding produces a higher quality repair than does plug welding, when replacing body panels. The finished product looks more “factory like”. There is less diminished value. Increase Customer Satisfaction To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503

Which Machine is Right for my Shop?:

Which Machine is Right for my Shop? You need to buy as much power as you can possibly afford. Buying on price alone or buying a welder with too little power will not help increase productivity and customer satisfaction, nor is it likely to satisfy the OEM requirements. Selecting the right machine will depend upon the types of jobs to be done, the available electrical power, and your shop’s revenues.

POWER REQUIREMENTS:

Not only must there be adequate power available in a repair facility, there must also be adequate power available where the spot welder will be used. The best equipment can not perform correctly if the source voltage is inadequate. POWER REQUIREMENTS To purchase AMH CompuSpot Products Call Pro Line Systems Int'l Inc. 305-793-9503
