In this pdf the Chart graphically shows the importance of Electrode maintenance. This is not only important from the quality of the weld, which is of the first importance, but also the extra load added to the welding machine and equipment. Read the data on the chart, you can then draw your own conclusions.

All welding department supervisors, plant safety officers and other personnel whose responsibilities include plant safety and/or installation, operation and maintenance of resistance welding equipment must take care to thoroughly familiarize themselves with all applicable codes, regulations and standards regarding the safe installation, use and maintenance of such equipment

Fabricators who are concerned with producing consistent quality welds should understand that electrode force, weld time duration and weld current intensity are closely related and a change in one parameter will affect the others. Increasing only the current without adequate weld force could result in severe expulsion or weld splash. A change in force without corresponding changes in current and weld time can also result in poor welds.

Multiple Guns For Efficient Resistance Spot Welding

Sheetmetal fabricators increase productivity and cut welding costs with series-type multiple-gun resistance welding machines.

The distance current travels to make resistance-spot welds determines the amount of impedance, resistance to current flow in the circuit. The longer the current path, the higher the impedance or power loss, in the circuit. In multiple-direct spot-welding machines, which use weld guns with large throats, current paths are long; setups have high impedances that require large transformers. Throat depth on these machines is typically 24 to 36 inches. The deeper the throat, the higher the power loss and the larger and more costly the transformer.

Using Dedicated Resistance Welders To Cut Costs

The need for lower cost production methods is not exclusive to high volume sheet metal fabricators. Unfortunately, many low volume fabricators have perceived multiple welders as costly and some resistance welder OEM’s as oriented primarily to the needs of high volume automotive and appliance manufacturers. In reality, RWC can also respond to the needs of low and medium volume fabricators with affordable multiple gun welders.

The fundamental difference between a remote transformer cable gun and an integral self contained portable spotwelder is the location, size and KVA ratings of the transformer needed to weld similar gauges of metal [illustration 1 & 2]. These differences can have a significant impact on the installation and operating costs of the selected equipment.

There are wire fabrication machinery alternatives to the European suppliers! RWC Bethlehem, PA of represents and supports Goldenspot Industries of Taiwan r ight here in North America! Instead of a Posi Wedler or Versa Welder for your wire fabrication utomation, consider the GoldenSpot SAAF dual layer mutli head welder in AC or MFDC. Impeccable Value speed! and twice the speed!

Several years ago, UNITROL received a panic call from a company that used a large number of our SOLUTION resistance welding controls. After two serious accidents within a six-month time period, OSHA gave them 45 days to either implement a system that would prevent pinch-point accidents on their spot welders or shut that department down. Since every part produced went through the spot welding department, this would effectively close their company, laying off over 1,000 workers.

TYPES OF WELDERS: SOFT TOUCH can be used with all types of metals on press welders, rocker-arm welders, portable gun welders, and hanging gun welders doing spot, projection and seam welding.

FULLY PASSIVE: There are no operator adjustments. Even if electrode height or travel is changed, the SOFT TOUCH system continues to function without any operator changes. In fact, there is nothing for the operator to adjust.
